Sunpower was created in the heart of the technology world in Silicon Valley, California in the year 1985. Ever since then, they have crafted and established themselves as one of the most reputable solar technology companies in the world. As a testament to that fact, they are amongst the longest continuing solar companies in the world, reaching their 40th year anniversary in 5 years.
Their longevity doesn’t just stem from their manufacturing of durable solar panels and energy systems, but rather – their constant development of new, innovative solar technologies. As such, their patented Maxeon Solar Technology can produce 75% more power over the first 25 years in comparison to your run-of-the-mill solar panel.
By using solid copper foundations behind their solar cells, they have ensured a material that is flexible while being durable, rather than the brittle silicon solar cells that other companies use. Due to this, your Sunpower solar panels last longer, while being able to trap more energy and sunlight to be absorbed.
It’s not just the ingenuity of the design that makes Sunpower solar panels so successful either – with their sleek black, gridless design, they make your rooftop look more streamlined and less gaudy in comparison to other solar panels. Now that we’re talking about solar panels, let’s go ahead and talk about Sunpower’s 370W Performance 3 panels versus their very own 395W Maxeon 3 panels.
SunPower is one of the leading solar panel producers in the world – and has been in business for more than 35 years. In that time – SunPower has procured over 3.5 billion solar cells, 35 million solar panels, and a panel return rate of 0.005%.
First, let’s talk about the 370W Performance 3 Panel. In comparison to its predecessors and other solar panels, it is a completely black solar panel – which will give a seamless look on top of your home. It’s beautiful, elegant, and most importantly – will absorb a huge amount of sunlight.
It has a product warranty of 25 years – which is a remarkable pursuit, as other solar panel manufacturers would only have a warranty of 10 to 15 years on their panels, if not less. This shows how much SunPower believes in the durability of the 370W Performance 3.
On top of that – there is a performance warranty for the 370W Performance 3 as well. Its performance warranty is at 87.2% – which means that even after the 25-year product warranty, it will still achieve at least 87.2% of its maximum efficiency. You’ll be getting the most out of the panel, and the most out of the energy it will transform for you.
The 370W Performance 3 also has “shingled cells.” This is a patented technology from SunPower.
The shingled cells allow you to still absorb sunlight even if one or more portions of the panels are covered in shade or low-light situations. This means that even if some parts of panels are covered by anything – it will still produce a tremendous amount of power.
Secondly, the 395W Maxeon 3. The Maxeon 3 have the same solar cells as those used by NASA on their spacecraft and space stations. It has the highest quality of solar cells on the market – and the panels themselves are protected by the very same 25-year product warranty that the Performance 3 panel has.
In terms of durability and flexibility – SunPower also has the patented technology of using copper backing for their solar cells. Regular solar cells on the market are brittle and are very easily broken. The Maxeon 3 solar cells are flexible, durable – and will last longer than traditional solar cells on the market.
Furthermore, there is a performance warranty on the Maxeon 3 panels as well. The performance warranty garners 92% efficiency, which means that after the 25-year warranty, the panel is guaranteed to be at 92% absorption efficiency. Again, you’ll be getting the absolute most out of any SunPower panel – but even more so with the Maxeon 3.
The Maxeon 3 also has an integrated Enphase Inverter.
Integrated Enphase Inverters prevent the loss of power from a singular solar panel being caught in shade or low light situations – which allows for the whole system to still flourish even during low-light seasons or within shaded areas. In essence, there is an inverter for every panel, which means that the transition from DC (Direct Current) power to AC (Alternative Current) power is at the highest efficiency.
If you’re looking for great, highly efficient, and durable solar panels – the Maxeon 3 and the Performance 3 will give all three of those attributes in spades. If you’re also looking for great warranties – the Maxeon 3 and Performance 3 both have a 25-year product warranty as well.
The technology used by the MAXEON 5 is the same solar cells that are used upon NASA spaceships and space stations – another key achievement of SunPower’s elite Research and Development team.
The MAXEON 5 is the flagship solar panel for SunPower – and is a 415W panel. Amongst other things, the product warranty for the MAXEON 5 is 25 years.
This bold warranty is another key testament to how much SunPower believes in its solar cell technology and panel durability. Whereas other competitors look to have their warranties from the 10 to 15-year range.
Speaking of warranties – the performance warranty of the MAXEON 5 is 92%. This means that after 25 years – the MAXEON 5 will continue to produce at least 92% of its original efficiency. The industry standard for drop-offs in energy efficiency is 81%. That is key for long-term solar energy users. The longer you have lower-grade panels on your home, the less that you are going to get from them in terms of energy transition efficiency. By switching to the MAXEON 5 – you get the most bang for your buck, all while paying less for energy over the long term.
The MAXEON 5 is at the top of its class, in terms of durability, reliability, and overall production power.
But that’s only the beginning. Many things make the MAXEON 5 so unique – one of those things is its integrated Enphase Inverter. An integrated Enphase Inverter means that there are inverters within every solar panel for your solar energy system. This prevents the loss of power from a singular solar panel being caught in shade – which allows for the whole system to still flourish even during low-light seasons.
Rather than using a traditional string inverter – the integrated Enphase Inverter directly converts sunshine from DC (Direct Current) power to AC (Alternative Current) power straight from the panel itself. This allows your solar energy system to be more efficient, aesthetically pleasing while having no loss in power from your panels to your home.
Additionally, you have a 25-year warranty on the Enphase Inverter – and as we have said earlier, the solar panels also have a 25-year warranty as well. These two components will certainly last you a long time and will have the durability to power your home for years on end.
The Enphase Inverters are located behind the solar panels and have a space between them and the solar panel for airflow. It takes a simple cable connection between each Enphase Inverter to create an overarching solar power energy system.
If you’re looking for quality, efficiency, and a great warranty – look no further than SunPower’s 415W MAXEON 5.

Most solar panel manufacturers entering the Australian market, first setup their distribution channels and worry about customer service later. This has led to many unhappy customers who are left trying to contact Chinese head offices to claim on their 10-year product warranty.
Relying on your solar installer is not always an option as we’ve seen many residential solar installers (including the large ones) go out of business well within the lifetime of the systems they are installing.
