First 400 Watt home solar panel
Maxeon solar panels are designed to be different, and proven to be better across more than 1 billion Maxeon cells and 30 million Maxeon panels, even in the harshest of conditions. Conventional solar cells lose power over time because of corrosion and breakage. The unique design of Maxeon solar cells eliminates 86% of the reasons that conventional cells fail1Wohlgemuth, J. “Reliability of PV Systems.” Proceedings of SPIE, 2008. So your SunPower panels - and savings - continue to deliver. Year, after year, after year.
SunPower recently released the Maxeon 3, the first 400 Watt home solar panel, breaking our own record.
As the most efficient solar panel in the industry for more than 10 years1Based on datasheet review of websites of top 20 manufacturers per IHS, as of May, 2019., Maxeon generates more power from the same roof than conventional panels. A SunPower Maxeon system delivers up to 35% more energy from the same space over the first 25 years.2SunPower 400 W, 22.6% efficient, compared to a Conventional Panel on same-sized arrays (310 W mono PERC, 19% efficient, approx. 1.64 m²)
Invest with confidence, knowing that SunPower® Maxeon® panel quality is proven. In actual field testing across 8 years and 800,000 panels at 264 sites, Maxeon solar panels demonstrated the lowest degradation rates in the industry,1Dirk Jordan et al, Robust PV Degradation Methodology and Application, March 2018 https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=8233204In partnership with the National Renewable Energy Laboratory (NREL), the U.S. Department of Energy’s primary national laboratory for renewable energy and energy efficiency research and development, SunPower developed a robust method to calculate solar panel degradation which is something all solar panels experience, but at varying rates. When this method was applied to eight years of energy performance data from 264 SunPower solar systems operating at various locations worldwide, it proved that SunPower panels degrade at a median rate of 0.2 percent per year: 70 percent less than the annual degradation rate for Conventional Panels.almost 4x stronger reliability than conventional panels. Maxeon panels are also backed by our industry-leading warranty.2Based on Jan, 2019 review of warranties on manufacturer websites for top 20 manufacturers per IHS 2018.

Frequently Asked Questions
How do SunPower Maxeon solar panels differ from Conventional Panels?
SunPower Maxeon panels deliver more bill savings and greater peace of mind than Conventional Solar Panels1“Conventional Panel” is a panel made with Conventional Cells. “Conventional Cells” are silicon cells that have many thin metal lines on the front and interconnect ribbons soldered along the front and back..
Maxeon solar panels deliver more bill savings by generating the most solar power and long-term solar energy in a given amount of roof space. Maxeon panels lead the solar industry in panel efficiency. That means they generate more power in the same space than all other panels on the market. In fact, our new Maxeon 3 panel is the first 400 watt solar panel in European and Australian home solar. In the same space, most Conventional Panels are rated for 280 watts – 310 watts. You would need 20 or more Conventional Panels to surpass the power generated by just 15 SunPower Maxeon panels in the same space.
Over time, the Maxeon advantage grows, because Maxeon panels also have the lowest degradation rate in the solar industry. While most Conventional Panels tend to degrade around 0.75%/year, our Maxeon have proven to degrade at less than one-third of that rate, or about 0.2%/year2SunPower® Maxeon® panels demonstrate 0.2%/yr annual power degradation. A robust method to calculate solar panel degradation, developed in collaboration with NREL, was applied to 230MW spread across 149 sites, 560 inverters, and 800,000+ panels. Jordan, D. et. al. “Robust PV Degradation Methodology and Application.” PVSC 2019 pre-print. To translate into real results – that means a SunPower Maxeon panel delivers 25% more energy in its first year of operation. In year 25, our advantage grows to about 45% more energy, for an average of 35% more energy during the first 25 years3SunPower 400 W, 22.6% efficient, compared to a Conventional Panel (310 W mono PERC, 19% efficient, approx. 1.64 m²).
Maxeon also delivers greater peace of mind. Our panels have earned the trust of experts by being more reliable and durable, and are backed by our industry-leading Complete Confidence Warranty. Not only is this warranty stronger, but unlike most conventional warranties, it is based on actual field testing data. For example, the Maxeon power warranty promises no more than a 0.25%/ year power drop – the strongest power warranty in solar4Based on Jan, 2019 review of warranties on manufacturer websites for top 20 manufacturers per IHS 2018. This is backed by a study of more than 230MW across 149 actual global sites using a methodology developed in collaboration with NREL. We also know from actual field data that only 0.005% or 1 in 20,000 SunPower panels have been returned under warranty5"A Comparative Study: SunPower DC Solar Module Warranty Claim Rate vs. Conventional Panels." SunPower Corporation. 2019.
Lastly, we build Maxeon panels with our customers in mind, which means higher sustainability standards and more elegant design aesthetics than Conventional Panels. SunPower has pioneered sustainability efforts in solar manufacturing, with our Maxeon panels leading the way. SunPower is the first solar company to earn the prestigious Cradle to Cradle Certified™ designation for its direct current (DC) Maxeon panels demonstrating the products' quality based on rankings of material health, material reutilization, renewable energy use, water stewardship, and social fairness.
SunPower is also the first and only solar manufacturer to disclose its panel ingredients through the Declare label – which we have done for all Maxeon 2 and 3 panels. In January 2019, a SunPower plant was re-certified by NSF Sustainability as Zero Waste to Landfill – we remain the only solar panel manufacturer to achieve this. The certification means that this facility diverts more than 99% of its waste, with 1% or less going to landfills. Finally, we have maintained our commitment to SunPower’s Global Takeback and Recycling Program Policy.
The back-contact cell design of Maxeon panels also delivers an uncluttered and elegant design aesthetic – and our panels are available in black and white backsheets. This has made Maxeon the panel of choice for architects and designers.
How do SunPower® Performance solar panels differ from SunPower® Maxeon® panel technology?
SunPower Performance solar panels utilize high efficiency mono PERC cells to deliver higher reliability and efficiency than Conventional Cells. For more information on Performance Panels, visit the performance panels page.
The Maxeon® panel advantage begins with its cell. The Maxeon cell is fundamentally different design from any other cell on the market, starting with a solid copper foundation that is unique in the solar industry.
In contrast, what appears to be metal on the front and back of a Conventional Cell is actually conductive paste made of tiny bits of silver and aluminum baked onto the silicon wafer. In fact, the process of making those cells is very similar to screen-printing a design on a tee-shirt: you create a template, wipe the paint across the template and then remove the template to leave the paint where you want it on the tee-shirt, and then bake the tee-shirt to cure the paint onto the fabric. A similar screen-printing process is used to apply the thin lines of metal paste on the front, and the full-coverage metal paste on the back, to create a Conventional Solar Cell. Unlike the strength of the solid copper foundation of the SunPower cell, the metal paste of the Conventional Cell offers almost no strength to the thin silicon wafer. This fundamental design difference creates the weakness you can find through basic laboratory testing.
What is the typical performance advantage gained from using SunPower Maxeon® panels?
A SunPower Maxeon solar panel delivers 25% more energy than a Conventional Panel in its first year of operation. In year 25, the difference would grow to about 45% more energy, for an average of 35% more energy during the first 25 years1SunPower 400 W, 22.6% efficient, compared to a Conventional Panel (310 W mono PERC, 19% efficient, approx. 1.64 m²). SunPower predicts its Maxeon solar panels will have a useful life of more than 40 years2SunPower Module 40-year Useful Life. SunPower whitepaper. 2013.
How much do SunPower Maxeon® panels cost?
With solar, as with many things, “you get what you pay for.” Not all solar systems are alike. The quality of the technology matters in the long run. The durability, reliability and efficiency of solar panels can vary widely by manufacturer. If you settle for Conventional Panels that might cost less out-of-pocket, you can expect to see average (or below average) results and less savings over time.
A higher quality panel like SunPower Maxeon might cost a little more up front, but you will see more predictable performance in the long run. SunPower Maxeon panels generate more energy, last longer, are backed by a stronger warranty, and are produced more sustainably than Conventional Panels. This means Maxeon panels will offset more of your electricity bill, saving you more, and do so with the peace of mind you expect from a top-quality product.
