Criteria for shortlisting the best solar panels in Australia for 2022

Most people want solar panels that are going to produce as much electricity as possible, for as long as possible – and at a reasonable price.

That means that the most important selection criteria will include panel efficiency, warranties and value for money. Also important is the ability of the manufacturer to honour the warranty over the longer term as well as panel durability, given the harshness of the Australian climate.

We’ll go through each of the selection criteria in turn to explain why it’s important.  Keep reading to get a good understanding of what to look for in a quality solar panel.

  1. Solar panel efficiency

Some industry pundits are dismissive of the importance of panel efficiency as a measure of quality. We disagree. Solar panel efficiency is important. It measures the amount of sunlight that solar panels absorb and convert to electricity. Given that the sole purpose of solar panels is to produce electricity, what could be more important than the rate at which they convert sunlight to power?

A few years ago, the typical efficiency rate for solar power was around 15 per cent. Now, better quality panels are 20 per cent efficient or more. Who wouldn’t prefer to have a panel that produces the higher amount of power?  It’s a no brainer!

Higher efficiency panels produce more free solar electricity per square meter of roof space.  With the trend towards the all-electric home, battery storage and electric vehicles, it makes economic sense to maximize the power generation potential of your rooftop by purchasing the highest efficiency panels you can afford.

Of course, high efficiency panels tend to come at a higher cost. It’s worth working out the difference in power generation output over a 25-year period. The extra power may well be worth the extra money.  Get in touch as this is something we can advise on.

  1. Warranties

Whilst the most important warranty with any solar panels system is the inverter warranty, it still pays to get the best solar panels warranty your money can buy.  Solar panels come with two different types of warranty from the manufacturer:

  • Solar panel product warranty
    • This warranty protects you from manufacturing defects. The industry minimum you should expect is 10 years; the best solar panels now have 25 years product warranty.
  • Solar panel performance warranty
    • This guarantees the amount of solar power that the panel will produce after 25 years, compared to its original output. Whilst this warranty is notoriously tricky to claim on, it provides a useful measure of the durability of the panel. The industry average is a minimum of 80% performance after 25 years. The best solar panels will have a performance warranty of 90% or more.

 

  1. Bloomberg Tier 1 rating

Warranties are only worth their salt if the manufacturer is still in business. That’s where the Bloomberg Tier 1 rating helps.  It provides a measure of the bankability and financial strength of the solar panel manufacturer. Given that solar panel warranties are for up to 25 years, it makes sense to choose panels from a manufacturer who’s likely to be around for the long-term to honour their warranties.

  1. Degradation rate

Degradation rate is the statistic you’ll find in the performance warranty section of the panels datasheet.  As mentioned above, the degradation rate states the percentage loss in power output from the solar panels at the end of 25 years compared to their day 1 output.

The best solar panels will have the lowest degradation rate. Whilst the percentage point difference between panel brands may be quite small, over a 25-year period the difference in power generation can add up. It pays to choose a panel with the lowest degradation rate you can afford.

  1. Performance in extreme heat

A lot of people think that hot sunny days are ideal for solar panels.  The truth is that solar panels need sunlight to work and the optimal operating temperature for panels is 25 degrees Celsius.

When temperatures soar, the rate at which solar panels generate electricity drops.  The question is by how much.

All solar panels will have a datasheet statistic called ‘a temperature coefficient of Pmax rating’. This tells you how much the panel’s efficiency is reduced by for each degree increase in the panel’s temperature over 25 degrees Celcius.

It’s important to note that this statistic relates to the temperature of the panel, not the surrounding air temperature. On hot days, the panel temperature will almost always be higher than the ambient air temperature making it quite possible for a panel to heat up to 50 degrees Celsius or more. In fact, a solar panel is usually 25 degrees hotter than the ambient temperature.

The bottom line is you want a panel with a Pmax rating that’s as close to zero as possible. Getting a panel with a low Pmax rating is particularly important if you live in one of the hotter climate zones in Australia.

  1. Price

The highest efficiency solar panels such as Sunpower or LG come at a price premium which is reflected in their extended warranties and impressive performance statistics.  If you’ve got the budget, purchasing Sunpower panels or another premium panel brand with a 25-year product warranty is well worthwhile. You’ll get fabulous solar power production with zero hassle for at least 25 years.

However, if budget is a consideration, there are excellent lower price panels – like Jinko – which will generate plenty of reliable solar power for your home over the warrantied period. These panels are produced to a high level of quality by manufacturers with customer support offices in Australia.

  1. Australian support office

This criterion is an absolute ‘must’ for anyone buying solar panels.  Whilst your solar retailer should be your first of call for a warranty claim on your solar panels system, you want a back-up plan in case they go out of business.  And that back-up plan should be to select a solar panel manufacturer that has a well-established customer support office in Australia – not some mickey-mouse office address that’s just for tax purposes.  This can be tricky to evaluate, so talk to us to get the lowdown on the quality of customer service provided by the different solar panel manufacturers on your shortlist.

Other criteria

Depending on your property and requirements, you may have other criteria for solar panel selection.  Probably one of the most common is finding a system that can handle partial shading. If that’s the case, it’s worth considering a SolarEdge optimizer with the Sunpower Performance 3 panels.   Sunpower Performance 3 panels use patented shingle technology; this means only the affected area of the solar panel stops working – not the whole panel.  It’s cool technology and worth a look!
