I have been in the solar industry for 15 years. Throughout that time, I've designed and installed for residential and commercial customers alike. I love saving people money, adding real value to peoples homes and helping create a greener future.
Understanding how a Solar feed-in tariff (FIT) can save you money is crucial to maximising your solar system and getting the best deals from electricity retailers. More Australian homes than ever before have installed solar panels, however very few people know what feed-in tariff rate they have with their electricity plans.
There are a number of solar bonus schemes in place across states and territories in order to encourage the switch to renewable energy. Solar feed-in tariff schemes – sometimes known as solar buyback schemes – essentially allow those with a solar power system to sell their excess solar power.
By sending the solar energy back into the electricity grid, your electricity retailers purchase it for a minimum feed-in tariff rate. These amount can vary greatly, depending on how many kilowatt hours (kWh) you produce, whether you have time varying tariffs, your retailer and your state.
If you don’t know how many cents per kWh you’re receiving, you want to reduce your electricity bills or you were confused about anything mentioned above, this article is for you. Below we will cover all of the basics. We will explain what a feed-in tariff is, compare the rates per state and retailer, and let you know some of the important variables to consider.
What is a Feed-in Tariff?
Simply put, a tariff is a payment imposed on an import or export. In this case, it is a payment from your retailer for the electricity that your solar system exports, or ‘feeds’, into the public grid. These tariffs have been used to incentivise clean energy and encourage homeowners to become positive contributors to the electricity grid.
Solar feed-in tariffs are viewed around the world as one of the most effective means of shifting energy consumption habits. Federal and State Governments throughout many developed countries have begun to implement these tariffs. We all know that money is a powerful motivator. As it turns out, using financial incentives may work to change attitudes towards sustainability.
Do you want to reduce your carbon footprint? Limit your dependence on the grid? Or simply earn money from your home or commercial solar system? Feed-in tariffs can help you achieve those goals.
Single Rate Tariffs & Time-Varying Tariffs (VIC)
Each year in Victoria, the rates of feed-in tariffs are determined by the Essential Services Commission (ESC). The ESC judges the value of solar energy by its market, environmental and social value.
“For the financial year beginning 1 July 2019, customers on the current minimum feed-in tariff will continue to receive a single-rate minimum feed-in tariff or a time-varying feed-in tariff. Electricity retailers may offer one or both of these feed-in tariffs to customers.”
These rates remain in place in Victoria until 30 June, 2020 when the ESC will reevaluate for the following financial year.
Retailers can give owners of a solar system the choice between a single rate, or time-varying tariff. They must offer at least the minimum tariff rate.
Feed-in tariffs from 1 July 2019 to 30 June 2020 (VIC)
The single rate minimum feed-in tariff is 12 cents/kilowatt hour. This applies regardless of the time that the energy is exported.
The time varying minimum feed-in tariff is between 9.9 cents and 14.6 cents/kilowatt hour. The rate you receive depends on the time of day that you export the electricity.
Solar Feed-in Tariff Rates per State | The Best and Worst
We have compared the rates of solar feed-in tariffs across each of the different states and the different energy providers. We have looked at the minimum rate and maximum rates that they offer in order to help you determine the best rate and energy provider for you.
Retailers offer varying rates depending on the plan you have with them. Retailers will change their rates each year, so it’s important to use this list as a guide and not a definitive pricelist. We have excluded retailers who offer rates of 0, as many of them do. The Feed-in tariff rates in each state are shown as cents per kilowatt-hours of electricity fed back to the grid.

Renewable energy has permanently altered the energy industry. In recent years we have seen unmatched growth in solar energy technology. Solar products are now more powerful, more efficient and more durable than ever before. A decade ago it was unfathomable that a large Australian company could be powered entirely by solar power. Now companies that aren’t powered by a solar pv system are at risk of becoming outdated and obsolete.Companies that use more than 1,500kWhs (kilowatt hours) of energy each day should install a 500kW solar system (500 kilowatts). If you are a large business with high energy bills then you are failing in two key ways, environmentally and financially. Your carbon footprint is as massive as your electricity bill. This is bad for your public image, bad for your profits and bad for the environment. All of these things can be solved by making the switch to solar.
The influx of new manufacturers and new products to the renewable energy market has meant that there is more choice than ever before. It also means that there is a wide disparity in the quality and price of available options. In this comprehensive guide to 500 kW commercial solar systems we will answer the most important questions:
What is the cost of a 500kW solar system?
What rebates & subsidies can I access for a 500kW solar system?
How much roof space is required for 500kW solar panels?
How much electricity will a 500kW system generate?
What value will a 500kW solar system bring my business?
How long is the payback period for a 500kW solar installation?
How do I improve the Return On Investment for my solar arrays?
What is the cost of a 500kW solar PV system?
The Changing Solar Market
Prices have fallen dramatically for commercial solar installations in the last few years. This means that many of the online price guides have become outdated and misleading. There are also more options to customise your system than ever before. Each component of your solar system can be catered to your budget and energy efficiency goals.
As such, it is important to get a personalised quote that includes your specific requirements and location in the calculation.
Solar Product Prices
Prices for a commercial 500kW solar installation start around $600,000 excluding GST. This price will depend heavily on your location and the type of components you choose for your system.
For higher quality components system prices will be $700,000 – $800,000 excluding GST.
Rebate
Commercial solar installations over 100kW in size are eligible for Large-scale Generation Certificates (LGCs).
This type of government rebate is distinct from Small-scale Technology Certificates (STCs). Instead of an upfront rebate amount offered at the time of purchase, LGCs are awarded annually based on the amount of solar energy your system produces.
While LGCs can be harder to quantify, they can provide a significant subsidy to the cost of your system over its lifetime.
How much roof space is needed for 500kW solar panels?
One of the key requirements for installing a commercial 500kW solar system is a lot of roof space. Exactly how much space you require will depend on the type of panels you choose. Most panels are 1.6 metres x 1 metre in size. The number that you’ll need to power your system will depend on the strength of the panels you select. Most are between 275 watts and 350 watts.
Below we have provided the rough calculations for the most common types of solar panels to give you an idea of the amount of surface area you’ll need to fit your system.
Roof space needed to power a 500kW solar PV system with:
275-watt panels would require 1,819 solar panels = approximately 2,910 m2
300-watt panels would require 1,667 solar panels = approximately 2,667 m2
350-watt panels would require 1,429 solar panels = approximately 2,286 m2
How much electricity will a 500kW solar pv system generate?
The amount of solar electricity that your 500kW system will generate will depend on the time of year and your location. Both of these factors determine the amount of solar irradiation that your panels will be exposed to. Summer will have longer days with higher solar irradiation levels compared to Winter. Likewise, Queensland will have higher levels of irradiation than Tasmania.
For an idea of the daily energy generation for a 500kW system, we have provided average production figures for each of the states.
State

How much value can a 500kW solar pv system bring my business?
Installing a 500kW solar system will bring a huge amount of value to your business. The reduction in your carbon footprint combined with the improved sustainability and public image are invaluable benefits.
On top of these intangible assets, the reduction in your energy bill will drastically reduce your company’s expenses. Most 500kW solar systems that have been appropriately fitted will save their business between $90,000 and $180,000 in electricity bills each year.
What is the payback period for a 500kW solar pv system?
One of the most crucial measurements in the value of a commercial solar system is its payback period. This is the amount of time it takes for your system to pay for itself. Through reduced energy bills, feed-in tariffs and LGCs, your solar system will eventually completely pay off the initial investment. After this period, the savings generated by your solar system are pure profit for your business.
The payback period is dependent on the initial cost of your installation, the quality of your components, the amount you pay for electricity and the amount of energy your system generates. Generally speaking, most 500kW systems will complete their payback period within 4 – 6 years.
How can I improve the Return on Investment for my 500kW solar system?
If you want to make the most out of your solar system, there are a number ways you can increase the ROI over the long term. Below we have listed three key areas to think about if you want to increase the value of your investment. For more information, visit our website for detailed articles on each of the following topics.
Solar Inverters
The solar inverter is the heart of the solar system. Inverters convert the energy from the solar panels into the electrical current used by your appliances. The higher the quality of your inverter, the higher the efficiency of this conversion. Investing in an inverter with high efficiency and a great warranty is the best way to boost your ROI and safeguard your investment.
Feed-in Tariff Rates (minimum feed-in tariff & time varying tariff)
The electricity that you generate that you do not use gets fed back into the grid. Each energy provider has different rates that they pay for the electricity you provide them. They also have different ways of measuring this rate. Some use a minimum tariff rate, while others vary their rate depending on the time of day. Doing your research to ensure you are getting the best rate from your provider.
Solar Battery Storage
For those who would rather not send their electricity back into the grid, solar batteries are your answer. These allow you to store your excess electricity for use at a later time. Batteries help businesses self-consume more of the energy they consume, which provides far better returns that feed-in tariffs.

Large commercial solar power systems are the secret to many Australian businesses cutting their expenses and boosting their profits. Switching your business to solar provides a range of financial, environmental and marketing benefits. The falling cost of solar installations combined with the changing energy market means that there has never been a better time to invest in commercial solar.Installing a 200kW solar system (200 kilowatt solar system) is an investment that will reduce your energy expenses over the long term. High quality 200kW systems have an expected lifespan of 25 years to 30 years. Once your solar power system has completed its payback period, your solar panels will continue to generate electricity and profit for your company.
Before you invest in a commercial solar panel system, it is important to do your research. In recent years many new manufacturers and products have entered the solar market. This has led to a rise in the amount of choices available and falling costs. However, it also means there are more products than ever that do not meet industry standards and should be avoided.
How much does a 200kW solar PV system cost?
What affects the cost of solar installations?
The cost of your commercial solar installation will vary depending on a number of variables. The state you’re in and the quality of the components you choose are major factors. Then there are the installation elements. These include the tilt of the panels necessary for your roof, the location of the inverter, the length of the cable needed and the type of roof.
For a general guide to the prices of solar installations, we have provided the starting prices for 200kW solar installations in each state.
Solar Product Prices
State
Solar PV System Cost
Queensland
$260,000 – $280,000
South Australia
$260,000 – $280,000
Western Australia
$260,000 – $280,000
New South Wales
$260,000 – $280,000
ACT
$260,000 – $280,000
Victoria
$270,000 – $290,000
Tasmania
$285,000 – $305,000
Rebate
Solar installations over 100kW in size are eligible to receive Large-scale Generation Certificates (LGCs). These LGCs are a part of the government’s Renewable Energy Target and thus are a form of rebate. This type of solar subsidy differs from STCs in that they are awarded over the lifetime of the system rather than an upfront discount. LGCs are given each year based off the amount of solar energy your system generated.
Estimates are hard to provide for the exact amount that a 200kW solar system can earn through LGCs. This is because the value of LGCs fluctuates and the amount of certificates that your system earns each year will vary depending on the amount of energy it produces.
How much roof space is needed for 200kW solar panels?
The amount of space you will need to install your solar arrays for your 200kW system will depend on a number of factors. These include the type of solar panels you choose, the space available on your roof and the way that your installer sets up the panels.
First you will need to understand the size of a solar panel. As far as its dimensions, generally speaking most solar panels are 1.6 metres x 1 metre. Then you will need to figure out how many panels you’ll need to power your 200kW system. Most solar panels are between 275 watts and 350 watts in power.
Below we have provided approximate calculations of surface area needed for the most common types of solar panels.
Roof space needed to power a 200kW solar PV system with:
275-watt panels would require 728 solar panels = approximately 1,164 m2
300-watt panels would require 667 solar panels = approximately 1,067 m2
350-watt panels would require 572 solar panels = approximately 915 m2
How much electricity will a 200kW solar pv system generate?
A 200kW system can produce somewhere between 150,000kWh (kilowatt hours) and 310,000kWh each year. This works out to be around 410kWh – 850kWh per day. This figure will largely depend on your geographic location and the quality of components in your system.
Systems located in areas with low solar irradiation levels should expect to be at the lower end of this spectrum. This includes states like Tasmania and Victoria.
Systems in states with higher solar irradiation, like Queensland and New South Wales, will generate levels closer to 800kWh/day to 850kWh/day.
How much value can a 200kW solar pv system bring my business?
On average, businesses in Australia with commercial solar installations of 200kW in size can expect annual energy savings between $30,000 and $60,000.
This figure will depend on the electricity rate you pay with your energy provider and the amount of solar energy that you self-consume. Companies that predominantly self consume the solar energy they generate could significantly outperform this estimate.
What is the payback period for a 200kW solar pv system?
The payback period of your solar installation is the amount of time it takes for the savings your system creates to cover the initial investment. After your solar panels have paid for themselves, all of the savings they create are net profit for your business.
This payback period will be determined by the amount you paid upfront, where you are located and the quality of the components in your system. Further factors such as your feed-in tariff (FIT) rate and the amount of energy you self-consume will also dictate the length of this period.
On average, Australian businesses that have been appropriately fitted for a 200kW commercial solar system will complete their payback period in 4 to 5 years.
How can I improve the Return on Investment (ROI) for my 200kW solar system?
There are many steps that you can take to maximise the ROI for your commercial solar system. Below we have listed three of the most effective means of increasing the value of your solar system.
For more information on any of the following topics, check out our other articles to go into more depth. To speak with an expert, contact our specialists on 1300 076 527 or through our website.
Solar Inverters
The solar inverter is one of the most important components of the solar system. The inverter is responsible for converting the energy produced by your solar panels into electricity that can be used by your business. The higher the quality of your inverter, the higher the efficiency of this conversion and the more electricity you’ll reap from your system.
Solar Battery Storage
Storing your excess electricity through a solar battery is a smart investment for any company. This process allows you to keep more of your energy for self-consumption rather than feeding it back into the grid. Self-consumption has the highest ROI for your electricity and thus will increase the value of your system in the long term.
Feed-in Tariff Rates (minimum feed-in tariff & time varying tariff)
If you don’t have a solar battery then it is important to understand your feed-in tariff rates. Each energy provider has different rates and means of measuring, whether that’s through a minimum rate or a time-varying rate. Check out our tariff article for more information.

Installing a 100 kilowatt commercial solar power system is the perfect way to cut your electricity bills, reduce your carbon footprint and boost your profits. The falling cost of solar products has resulted in many Australian businesses making the switch to solar energy. Taking advantage of clean energy is a great way to improve your brand in the modern economy. It shows business savvy to embrace forward-thinking energy solutions.
A 100 kilowatt solar photovoltaic system (100 kW solar pv system) is ideal for medium to large sized businesses with high energy costs. Installing solar can be extremely cost effective. Federal government and state government solar rebates help to reduce the upfront installation cost. 100kW systems have payback periods of just a few years, which is nothing compared to the 25 year lifespan of the system.
Power bills are a huge burden for large businesses. Australia wide, electricity costs have been rising significantly in recent years. Installing solar for businesses allows companies to turn this problem into an asset. Through energy cost reduction and electricity tariffs, your solar arrays will quickly pass their payback period and become highly profitable over the long term.

The Changing Solar Market
In recent years solar technology has improved and more manufacturers have entered the market. This has resulted in prices falling and product choices increasing. Businesses looking to install commercial solar are now able to customise their systems to suit their needs. Finding a balance between commercial solar costs and energy efficiency is easier than ever before. For this reason it can be difficult to find an accurate estimate on the price of a commercial solar system. The range of prices has become so broad due to the number of ways you can customise your system. From the inverter and solar battery options, to the number of cells and type of technology in your solar panels. Prices also differ depending on which state you live in and the rebates available to you.

Rebates (STCs & LGCs)
The amount of money you can save through government rebates are based on where in Australia you live. The Renewable Energy Council (REC) split the country into four zones based on the levels of solar irradiation in those areas.Those zones are each offered different levels of subsidies for the purchase of solar products.
The level of subsidy you receive is also dependent on which rebate you are eligible for. There are two distinct types of rebate.
Small-scale Technology Certificates (STCs) are available for purchases of solar systems that are under 100kW in size. These certificates are given as an up front rebate based on your solar system size.
Large-scale Generation Certificates (LGCs) are awarded to solar systems that are 100kW or larger. These certificates are not awarded upfront as they are with the STCs. Instead they are awarded annually based on the amount of energy your system generates. As such the amount you recieve is provided over the lifetime of your system rather than a single upfront payment.
The amount of certificates you receive per kilowatt varies in different zones. The value of certificates also fluctuates, making it difficult to provide you with an exact estimate.
As an example, in Melbourne you will receive roughly 14 STCs for every kilowatt of energy installed. Where the price of certificates is $35, this would result in a $49,000 upfront discount for a 99kW System. Installing a 99.9kW system would make you eligible for STCs rather than LGCs. In many cases STCs have a greater ROI than the large-scale rebate.
How much roof space is needed for 100kW commercial solar panels?
The amount of roof space that you will require will depend on the exact dimensions of the solar arrays that you choose. Lower quality panels with less efficiency will require more panels to generate 100kW. Higher quality panels will require less panels and therefore less space. Two key components to calculating the roof space required are the power of the panels and the size of the panels:
Most types of solar panels will be between 275 watts and 350 watts
Most panels are approximately 1.6 metres x 1 metre
Roof space needed to power a 100kW solar PV system with:
For an idea of the amount of roof space you will require for solar panels to power a 100kW solar system we have provided a guide below. These are approximate estimates based on the most common panel types. For an exact estimate of the roof space required for your commercial solar installation, contact our specialists on 1300076527.
275-watt panels would require 364 solar panels = approximately 582 m2
300-watt panels would require 334 solar panels = approximately 534 m2
350-watt panels would require 286 solar panels = approximately 458 m2
How much electricity will a 100kW solar pv system generate?
The amount of electricity that your commercial 100kw solar pv system can generate is based on the quality of the components in your system and the amount of solar irradiation it is exposed to.
As such, a 100kW solar system in Brisbane will generate more solar energy than the same system would in Hobart. A 100kW system with a high quality inverter and panels will produce more electricity than a 100kW system with lower quality components in the same location.
Generally speaking you can expect your 100kW commercial solar system to generate around 150,000kWh (kilowatt hours) of energy each year. This works out to be 411kWh per day. This average takes into consideration the differences across locations and types of systems. You could therefore expect to produce more than this with high quality components and in areas of high solar irradiation.
How much value can a 100kW solar pv system bring my business?
A 100kW solar system is sure to save your company costs on energy bills while adding value in your sustainability profile and public image. In terms of quantifying your Return On Investment (ROI), that will depend on a number of factors.
How much you pay for electricity and the amount of electricity your business uses are two key considerations. You must also consider how much you paid upfront and how much of the costs you had subsidised by a government rebate. Some rebates can cover up to 45% of the initial price.
Most businesses with 100kW solar systems report annual savings between $20,000 and $50,000.
What is the payback period for a 100kW solar pv system?
The “payback period” of your solar installation is the amount of time it will take for your system to pay for itself. Through your reduced energy bills and tariffs earned from feeding excess energy back into the grid, your solar production will eventually cover the upfront costs of the system. Once you have completed this period, all of the energy produced by your system can be regarded as direct profit for your business.
With the aforementioned factors like rebates, energy prices and component quality taken into consideration, most 100kW commercial solar installations will complete their payback period within 3 to 5 years.
How can I improve the Return on Investment for my 100kW solar system?
There are many ways to improve the ROI of your system. Ensuring your system is appropriately sized for your energy usage is the most important step. After this, you can boost the efficiency of your solar system by choosing high quality components.
Finally there is the choice of what you do with the electricity you generate. Self-consumption has the highest value, as this way you are reducing the costs of buying electricity from an energy provider. If you are producing too much electricity to consume, you should then weigh up the value of either feeding that back into the grid for a tariff, or storing it with a solar battery.
Solar Inverters
Solar inverters are the part of your system that converts the energy you receive from the sun into usable A/C electricity for your home or business. The better your inverter, the higher the efficiency of this conversion. It’s always best to get a high quality inverter with a reliable warranty.
Solar Battery Storage
Storing your excess electricity is a great means of boosting your ROI. Rather than relying on the tariff rates offered by your energy provider, batteries allow you to retain your electricity for use at your convenience.
Feed-in Tariff Rates (minimum feed-in tariff & time varying tariff)
If you don’t have a solar battery, you should ensure you are getting good rates of tariffs from your energy provider. For more information on FITs, including minimum feed-in tariffs and time varying tariffs, check out our page on feed in tariffs.

How much roof space is needed for 50kW solar panels?
The amount of roof space you have plays a crucial role in your selection of solar panels. Those with ample roof space have the luxury of choosing the panels that best suit their budget and efficiency goals. However, if your roof space is limited then you may need to buy more powerful panels to make the most of the space you have.
While some manufacturers and types of panels will differ slightly in dimensions, generally speaking the measurements of most solar panels are 1.6 metres x 1 metre. Most panels range between 275 watts and 350 watts. This leaves a decent amount of options in finding the perfect type of panels to suit your budget, goals and roof space.
Roof space needed to power a 50kW solar PV system with:
Below we have provided a guide to the surface area required for some of the most common panel sizes available on the solar market today. The calculations provided are rough estimates of the amount of roof space that would be needed to generate 50 kilowatts.
275-watt panels would require 182 solar panels = approximately 291.2m2
300-watt panels would require 167 solar panels = approximately 267.2m2
350-watt panels would require 143 solar panels = approximately 228.8m2
How much electricity will a 50kW solar pv system generate?
The amount of electricity that your 50kW commercial solar system will generate will depend on a variety of important factors. First and foremost is your geographic location. Where you are situated in the country will determine the amount of solar irradiation that your panels are exposed to. For this reason businesses in the Northern Territory and Queensland can expect to produce more solar energy than those in South Australia or Tasmania.
The time of year is another key consideration. Clearly you can expect to reap more electricity from your solar panels during summer than you will during winter. Longer days and less cloud coverage will all result in higher amounts of electricity produced.
Finally there are the numerous smaller factors that contribute to your overall power generation. The quality of the components in your system, such as the panels themselves and the inverter you choose will affect the efficiency of the system. Then there are the installation factors like the angle of the panels and whether they have been placed under any partial shading.
For these reasons we can not provide an exact figure on the amount of electricity that your 50kW solar system will generate. Instead we can provide you with an average that will give you an approximate average of what your solar system could produce each day.
For systems located in lower-yield locations such as Tasmania or South Australia, you can expect an average of 180-200kWh (kilowatt hours) per day. For higher-yield states like Queensland and Western Australia this goes up to 200-220kWh/day.
How much value can a 50kW solar pv system bring my business?
50 kilowatt solar power systems are suitable for medium to large sized businesses with energy usage under 500kW per day. Investing in this type of solar product will make you eligible for the government’s Small-scale Technology Certificate (STC) rebate. This will entitle you to a subsidy on the upfront cost of the system and will ultimately result in a greater return on your investment.
Offsetting 200kWh of electricity each day will dramatically cut your energy expenditure. This will result in cuts to your overhead costs and an increase in your net profits. Businesses with 50kW solar pv systems on average across Australia report energy bill savings of approximately $16,000 annually.
What is the payback period for a 50kW solar pv system?
Through offsetting your energy bill with solar energy and the tariffs paid from feeding electricity back into the grid, your system will eventually pay for itself. Once it has completed this payback period, your investment will become a positive cash-flow product for your business.
The average time for 50kW commercial solar systems to complete this payback period is 4 – 5 years. This will depend on the rate you pay for electricity, the rates of tariffs you receive from your energy provider and the amount you self-consume.
How can I improve the Return on Investment for my 50kW solar system?
There are many ways that you can boost the efficiency of your system and improve the Return on Investment (ROI). Below we have provided four such measures to improve the energy production of your system and the ultimate value of your investment. For more information on any of these concepts, visit our library of articles on our website.
Solar Rebates & Subsidies
State and federal government rebate programs are designed to incentivise the purchase of solar products for personal and commercial use. These subsidies can massively discount the upfront cost of your system, reducing the payback period and improving your overall returns.
Solar Inverters
The quality of your solar inverter will determine the efficiency of your system. Inverters are responsible for converting the energy generated by your panels into the energy you use everyday. The better your inverter, the more electricity you will reap from the solar you generate.
Solar Battery Storage
Solar battery storage is the best means of increasing the amount of solar electricity that you self-consume. Using the energy you generate yourself offers the highest value and thus the greatest returns. Instead of feeding excess energy back into the grid, you can hold onto it for consumption at your convenience.
Feed-in Tariff Rates (minimum feed-in tariff & time varying tariff)
If you don’t have a solar battery and you don’t consume 100% of the energy you generate, it’s important to understand your feed-in tariff (FIT) rates. Different energy providers have vastly different rates and means of measuring the energy you feed back into the grid. Do your due diligence and check out our article on FIT rates.

If you’re still paying full price on electricity bills for your business then you’re losing money. Commercial solar is the way that Australian businesses are harnessing renewable energy to lower expenses and boost profits. A 20 kilowatt solar pv system (20 kW) is ideal for small to medium sized businesses.
A 20kW system will produce enough solar energy to power your business, payoff the system cost and become a profitable investment in just a few years. Before you rush out to create your own solar farm, you should understand the role of each of the components of a commercial pv system. This is important to understanding how to get the most value out of your solar power system.
System prices vary greatly depending on the state you’re in, the manufacturer of the product and the solar installer you choose. For this reason you should choose an installer that has been pre-vetted by the Clean Energy Council (CEC) for quality assurance.
20kW Commercial Solar FAQs
It is important to do your research and have a good understanding of the renewable energy product market before making an investment into commercial solar. This is made difficult by all the conflicting information online. To make things simpler, we’ve created this comprehensive buyer’s guide to 20 kW solar pv systems for businesses.
In this guide we will answer your most frequently asked questions about 20 kW solar systems:
What is the cost of a 20 kw commercial solar PV system?
How much roof space is needed for 20 kW solar panels?
How much electricity will a 20kW solar pv system generate?

What is the cost of a 20kW solar PV system?
The Changing Solar Market
There has never been a better time to make the switch to solar energy for your business. The last decade has seen the price of commercial solar installations fall dramatically. As solar costs have been plunging, the power of solar technology has been rising exponentially.
Solar pv systems are far more powerful, efficient and durable now than we could have imagined a decade ago. Solar panels lasting longer and generating more electricity all translates to more value for your solar investment.
The cost of solar PV systems vary significantly depending on a number of factors. Location is one of these influencing factors. The state you’re in will determine the starting price of solar products. In order to reach the national renewable energy targets, the government created rebates in order to incentivise the use of solar products.
The size of these subsidies is based on the amount of solar radiation in different parts of the country. For these reasons the prices vary for solar systems around the nation.
Solar Product Prices
Prices for solar products also depend on the quality of product you choose, the manufacturer who produces them and the solar installer who fits them for you. Installation costs can then fluctuate based on the type and condition of your roof, the demand for installation at the time and the quality of panels being fitted.
Each of the above elements factor into the cost of solar systems. For this reason you will not find highly specific prices for solar products and installation that will be tailored for you. A rough guide for the cost of a 20kW solar PV system in Australia is anywhere between $20,000 – $35,000.

How much roof space is needed for 20kW solar panels?
The amount of roof space you will need will be dependent on the type of solar panels that you power your system with, the angle of your roof and other factors like the layout and condition of your roof. However as a general rule, the surface area of the average solar panel is 1.6 metres x 1 metre.
The more powerful the solar panels you choose, the more efficient they are and therefore the less you will need to generate 20 kilowatts. Solar panels generally range between 275 watts and 350 watts per panel. For a rough idea of the amount of roof space you will need to fit solar panels to your business, we have provided calculations for the most common types of panels.
Roof space needed to power a 20kW solar PV system with:
275-watt panels would require 73 solar panels = approximately 117 m2
300-watt panels would require 67 solar panels = approximately 108m2
350-watt panels would require 58 solar panels = approximately 93m2
How much electricity will a 20kW solar pv system generate?
The amount of electricity produced by a 20kW system is influenced by your location and the time of year. Where you live in the country to a large extent dictates the amount of solar irradiation that your panels will have access to.
Evidence of this can be seen in the average solar production across our capital cities. Hobart has the lowest rates of production while Darwin has the highest. This is a clear result of their geographic location.
Further factors like the angle of the panels and whether there is any shade over the roof will have an effect on the production rates. For this reason it is vital to use experienced, CEC-accredited installers who know how to maximise the efficiency of your system.
Broadly speaking, throughout the year across Australia a 20kW solar system will generate somewhere between 60 kilowatt hours (kWh) and 90kWh.
Businesses in most parts of the country can expect their 20 kW commercial solar PV system to produce approximately 80kWh per day.
How much value can a 20kW solar pv system bring my business?
The amount of savings that your business could reap from the installation of a 20kW solar pv system will depend on the amount you pay for electricity and the amount of electricity that you use.
Most installations of 20kw solar for businesses self-consume 80-85% of the electricity they generate. These commercial installations report savings around $8,000 annually. This figure comes from a combination of reduced electricity costs from using solar and the discounts offered by energy providers through feed-in tariffs (FIT).
Therefore businesses who self-consume more than this amount, or with great FIT rates have the potential to save even more.For information on the rates of feed in tariffs across the different states and the minimum tariffs available, read our article on feed-in tariffs .
What is the payback period for a 20kW solar pv system?
Completing the payback period of your commercial 20 kw solar system is a key milestone in your path to bringing profit to your business through renewable energy. Once the savings your solar system has brought you outweigh the upfront costs, you can enjoy many years of sustainable savings thanks to your initial investment.
The average payback period for commercial 20kw solar pv systems in Australia is between 3 and 5 years. When you take into consideration the 25-30 year lifespan of a quality solar pv system, this leaves you with 20-25 years of positive cash flow to your business.
How can I improve the Return on Investment for my 20kW solar system?
There are numerous ways to boost the efficiency and value of your system to ensure you’re getting the highest return on your investment. Ensuring you buy quality components with reliable warranties is one way to protect your investments. Each of the following elements can help you to stretch your solar dollar further.
Solar Rebates & Subsidies
Ensuring you take advantage of the federal and state rebates on offer is a simple way to lower the upfront cost of your system and shorten the payback period. Speak with our specialists or visit our rebate page to learn more.
Solar Inverters
High quality solar inverters are the key to improving the efficiency of power conversion within your system. The better your inverter, the more electricity you will reap from the solar energy you generate.
Solar Battery Storage
Solar battery storage is a smart investment for those who want to maximise their investment by self-consuming most of their energy. Self-consumption has the highest rate of return, so rather than feeding the excess back into the grid, hold onto it for a rainy day.
Feed-in Tariff Rates (minimum feed-in tariff & time varying tariff)
If you are going to send your excess electricity back into the grid, make sure you’re getting a good rate for it. Check out our feed-in tariff page or give us a call to learn more.

Size & Specs of a 9.9kw Solar System
The size and specifications of your solar system will depend on the type of solar panels that you use. Solar panels are in most cases 1.6m x 1m in size. Most panels installed these days are between 415 watts and 440 watts.
How much roof space do you need for a 10kW system?
To generate 10 kilowatts of solar energy using 60-cell panels of 440 watts would require 23 solar panels. This would therefore require 57.6m2 in roof space and generate 9,900 watts (making it a 9.9kW system).
For systems with 60-cell panels of 415 watts you would need 24 panels. This requires 52.8m2 of roof space and generates 9,900 watts of solar energy (also making this a 9.9kW system).
Using 72-cell panels of 350 watts would require 28 solar panels. This would need 44.8m2 of roof space and generate 9,800 watts (making this a 9.8kW system).
From these examples you can see that there are a lot of answers to the question of how much roof space you will need for a 10kW solar system. Broadly speaking a 10kW system will need between 23 and 28 solar panels. This will require between 44m2 and 58m2.
Who is the 9.9kW System Right For?
Generating up to 10kW of solar electricity isn’t necessary for everyone. Small houses or houses with low energy usage should definitely be looking at smaller system sizes. However, for large homes with high energy usage and big appliances this may be the perfect investment for you.
If your electricity bill is in the realm of $800, then 10 kilowatts of solar power could end up saving you a fortune. Home additions like reverse cycle air conditioning, pools, home automation and pool pumps can all drive your electricity bill sky high.
Small businesses are another prime contender for 10kW solar systems. Consistently high energy usage throughout the day means that you could be making maximum savings by offsetting those costs through solar energy.
9.9kW Solar PV System Value For Money
To get the most value for money from your solar system you will want to be self-consuming most of the power that you generate. Sending excess electricity back into the grid can reduce your energy bill and save you money. However, the rate for feed-in tariffs is less than what you pay for electricity from the grid. This means that you will get a greater return from your system if you are consuming the majority of the power that you generate.
While you will start saving money from the moment you have your 10kW solar system installed, the true value for your money will come after the payback period. This is the time it takes for your system to pay for itself through the savings that it generates in your energy bill. The average payback period for 10 kilowatt systems is around 4 years.
The amount of time it takes for your system to complete this period will depend on where you live as that will dictate the amount of sun you receive and the amount you paid for upfront costs.
You can expect your system to efficiently work for 25-30 years. This means that you can hope for 20-25 years of your system providing you with direct profit through your greatly reduced energy bills.

Increase the value of your investment
Solar Rebates
Government subsidies and state rebate initiatives can drastically lower the upfront cost of your 10kW solar system. Not only does this make solar energy more affordable, but it reduces the payback period of your device. This means that your system can become profitable sooner, giving you a greater return on investment and improving the overall value of your system.
For more information on subsidies available to you, check out our article on rebates .
Feed-in Tariffs
The rate of feed-in tariffs that you receive will depend on which state you’re in, which energy provider you choose and which plan you’re on. The amount you can save from the electricity you send to the grid will also depend on whether you choose a time-varying tariff or a fixed rate. For information on the rates of feed in tariffs across the different states and the minimum tariffs available, read our article on feed-in tariffs .
Solar Inverters
The quality of your inverter will determine the level of efficiency of your solar system as a whole. Inverters determine the efficiency in converting the solar power into usable electricity. One of the best ways to increase the value of your system and improve your ROI is to purchase a top end inverter from a reliable manufacturer.
Any home or business that is looking at investing in a 10kw solar system should be thinking about a solar battery storage device too. Solar storage capacity can ensure that your investment is safeguarded and that no energy is lost. Rather than relying on lower rates of feed-in tariffs, batteries allow you to store your electricity. This means that you can use more of your electricity for self-consumption, which has the highest value and return on investment.

Anyone looking for a cost effective way to lower their electricity bill should be considering a solar energy system installation. A solar power system is a means of accessing renewable energy while also reducing your carbon footprint and your expenses.
Your system can start to make you money once it has paid off the initial cost of the installation. There are a number of ways that your home solar panels can complete this payback period. Feed in tariffs, government rebates and reductions in your electricity bill all contribute to your return on investment (ROI).
Many homes that have already installed solar panels will be using 5kw solar systems with 5kw inverters. However, as technology has improved and prices have dropped, getting a larger system size has become more accessible. 6.6kw solar systems (often referred to simply as a 6kw solar system) have become one of the most popular options for powering the home.
6.6kw of solar has become preferable due to the extra energy you can generate for your home without much extra expense. This size system will generally consist of 24 panels. Luckily you will not need to increase your inverter capacity, as 5kw inverters are compatible with the 6.6 kilowatt solar panels.
In this article we will cover everything you need to know about a 6.6 kw solar system including Price of 6.6kW Solar System. We will look at the price of 6.6kw solar system, size, value for money, solar battery storage and inverters.
Price of 6.6 kw Solar System
The falling price of solar products has meant that the technology available for Australian homes has been getting more and more powerful. While 5 kilowatt solar panels used to be the norm, homeowners have now got access to the significantly larger 6.6kw systems without having to overstretch their budget.
Not all 6.6 kilowatt solar systems are made equally. This means that reputable manufacturers will charge a premium on their products because they are made from higher quality materials that are built to last. You will find a wide array of different prices online due to the range in quality and reliability of the manufacturers and their products.
Prices will also differ slightly between states, so it’s important to get an accurate quote for your specific location. For an idea of Price of 6.6kW solar system we have provided a price guide below for systems including installation, warranty and support.

Size & Specs of a 6.6kw Solar System
The size and specifications of solar panels have been constantly changing as the technology is improved and updated. Unlike many other pieces of modern technology however, smaller is not always better. The amount of surface area on solar panels is obviously essential to the amount of energy that can be obtained.
Choosing the right solar panels for your home and energy needs is vital to maximising the efficiency of your system with the amount of roof space you have available. These systems will tend to use between 250 watt (W) and 400W modules. Broadly speaking, 6.6 kilowatt solar systems will require approximately 22 to 24 panels. The system will therefore require a decent amount of roof space.
Each solar panel is roughly 1.7m x 1m in size. This means a system consisting of 24 panels will require 41m2.
Value For Money From 6.6 Kilowatts
The 6.6 kw solar panels have become more popular due to the increased energy output and value for money compared to the 5 kw solar panels. The bigger systems are not only cheaper than they were a few years ago, they also give owners access to a larger government rebate. The larger kilowatt hour (kWh) potential of the system means a larger discount, increasing the value for money and the ROI.
The lower cost per watt of the solar system is a massive benefit of the upsized system. Federal solar rebates differ between states. You can expect a discount of somewhere between a quarter and a third of the price of your initial investment. For more information on the rebates available to you, contact our specialists today.
Solar Energy Battery Storage
The lowering cost and improving technology of solar battery storage is another key reason that 6 kw solar systems are so popular. The larger solar system produces more energy, which for smaller homes may not always be used. However, with the addition of solar battery storage, this excess electricity can be retained and used when it is needed.
Owners of solar technology love the addition of a solar battery as it gives them independence from the grid. Grid outages and low levels of sunlight are no longer an issue once you have a backup source that can power your home with the excess solar energy you have created throughout the week or month.
Investing in a bigger solar system no longer requires you to spend more on your inverter. This is because with a 6.6 kw solar system you can still use a 5 kw inverter. The 5kw inverters are much more common, making them cheaper and more widely approved for grid connection (almost every network has them pre-approved).
The Clean Energy Council (CEC) guidelines allow for a solar power system to be oversized by 133%. This means that the 6.6kw system is perfectly legitimate and compatible with a 5kw inverter. The oversized system is popular due to the greater energy yield and value for money.

With the financial incentive of the Federal and State Governments’ solar rebates, Australian households are installing rooftop solar panels and home solar power systems at an unprecedented level.
These high subsidy levels – offered in the form of Small-scale Technology Certificates (STCs); Large-Scale Generation Certificates (LGCs); SA Home Battery Scheme for South Australians; and the Solar Victoria Rebate for Victorians – are gradually decreasing in value. It is therefore important for anyone considering the switch to renewable energy to understand the financial incentives, rebates and subsidy schemes available to make installing a solar system as affordable as possible.
Solar panels, home battery systems and feed-in tariffs all help to reduce the cost of your electricity bills. While this can provide a huge return on investment over the 25 year lifetime of your solar device, the upfront installation costs are prohibitively steep for many Australians. That’s why we have created this simple guide to solar rebates, to make sense of the various government financial incentives and options to make the switch to solar as easy and accessible as possible.
This comprehensive guide to solar rebates will discuss:
The Solar Credits Program | Renewable Energy Certificates (RECs)
South Australian Home Battery Scheme | State Rebate
ACT Next Generation Energy Storage Grants Scheme | State Rebate
The Solar Credits Program | Renewable Energy Certificates (RECs)
Technically this scheme is not a rebate, the government’s Solar Credits program aims to help Australia reach its Renewable Energy Target by creating a marketplace for renewable energy certificates (RECs). This program rewards renewable energy production with certificates (RECs) which can be sold on an open market. Companies that produce high volumes of fossil fuel will then purchase these certificates to increase their clean energy generation. RECs come in two forms: STCs for systems under 100 kilowatts (kW) and LGCs for systems over 100kW.
The price of these certificates fluctuate with the market, but generally sit around $30-$40 each. This scheme will gradually decrease in value over the next decade until 2030. This means that the best time to take advantage of the government rebate scheme is now, as you will gain the highest subsidy and return on your investment.
Small-scale Technology Certificates | Federal Rebate
Small-scale Technology Certificates, or STCs, are a Federal Government subsidy scheme available for purchases of solar systems under 100kW in size. These certificates are rewarded based on the amount of kilowatt hours (kWh) of electricity that your system is expected to generate. The certificates can then be sold on the market by you, or an accredited solar installer on your behalf. This then provides a discount on the upfront installation costs of your system.
The amount of STCs available to you depends on the size of the system you purchase, when you purchase it and where you live. Australia has been divided into 4 zones that determine the amount of renewable energy certificates that you are eligible for. Your postcode will determine which zone you fall under and therefore the size of rebate available to you.
Broadly, the zones are as follows:
Zone 1 – Northern parts of the Northern Territory and Queensland
Zone 2 – Central Australia and northern parts of Western Australia
Zone 3 – Western Australia, Queensland, New South Wales and South Australia
Zone 4 – Tasmania and Victoria
To give you an idea of the potential rebate available for household solar systems, we’ve provided a rough guide. For a more precise estimate based on your location, you can find an STC calculator here.

Large-scale Generation Certificates | Federal Rebate
LGCs, or Large-scale Generation Certificates, are awarded to new purchases of solar systems that are over 100kW in size. Unlike STCs, LGCs are awarded on an ongoing basis and are based off the actual power generation of your device. This means that they are not awarded as an upfront discount on your solar installation. Instead, a monitoring device will track the output of your system which you will use to apply for your certificates each year.
More information on LGCs and the calculation of their value can be found at the government’s Clean Energy Regulator website.
Victorian Solar Scheme | State Rebate
The Victorian Solar Scheme is offering a rebate up to $1,888 for the purchase of new solar panel (PV) system installations (as of December 2019). In addition to this rebate, the Victorian state government offers an interest-free loan equivalent to the size of your rebate, which can be paid back over 4 years.
To be eligible for this rebate, you must meet the following criteria:
You are the owner-occupier of the property
You have a combined household taxable income of less than $180,000 per year
You are in an existing property, valued at under $3 million
You do not have an existing solar PV system

Comparing prices for solar panel costs can be a difficult task with the amount of online shops and price comparison websites advertising different panel prices for their solar power systems. That’s why we’ve created this simple guide that compares prices to give you a clear answer on the cost of each of the major solar panel brands.
This total cost can be reduced with the help of the Federal Government’s solar rebates, which can offer discounts on the solar installation costs based on the number of STCs (Small-scale Technology Certificates) that your system earns. For a more precise esalignnonetimate based on your location, you can find an STC calculator here. If you would like to learn more about the Government’s renewable energy subsidy scheme, have a look at our article on Solar Rebates.
The Best Three Solar Panels to Install
1. EGing
With over 17 years worth of experience and an elite-level Research and Development team, EGing PV stands amongst the top-level performers in all of China in terms of solar panel manufacturing and production. Their vertically integrated business model allows them to have the best solar panels while maintaining a great price for consumers.
Their EG-415 is the flagship of their solar panels and is recognized as one of the most efficient panels in the world. The 415W uses a multi-busbar technology pattern, which decreases the resistance loss between your solar panels and your solar inverter unit.
Its solar panel modules can achieve 21.22% efficiency, while having textured solar cell surfaces which allows for great performance, even in low-light or shaded areas. This is due to their half-cell technology. The half-cells can gather more photons even if the panel is partially shaded, which means that you will not lose efficiency if there is something blocking a portion of, our panels. The half-cut cells work in unison with the multi-busbar, which brings about lower resistance levels with higher power output.
Their warranties include a 20-year product warranty on all their panels, with a 25-year linear power warranty as well. Take a deeper dive into the EGing panels with our EGing Solar Panel review.

This solar panel cost comparison table provides a clear view of the range of prices between the major solar energy brands and the price jump between the different sized solar systems.
One notable price difference is between systems with a basic inverter and a premium inverter. Inverters convert the DC electricity created by your solar panels into usable AC electricity that can power your home and everything in it. The higher the quality of your inverter, the greater the efficiency of the conversion. This means that your inverter plays a large role in the amount of electricity you can get out of your panels. The premium inverters have a steeper upfront cost, however over the lifetime of your solar panels this can result in a greater return on investment.
