High Efficiency Solar Panels SolarStratos

Fundamentally different,
and better

SunPower Maxeon solar panels are designed to be different, and proven to be better across more than five cell generations, 3.5 billion cells and 30 million panels, even in the harshest of conditions. Conventional solar cells lose power over time because of corrosion and breakage. The unique design of SunPower 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.

Maximum power

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 Jan, 2020. , SunPower Maxeon panels generate more power from the same roof than conventional panels, delivering up to 35% more energy from the same space over the first 25 years.2SunPower 450 W, 22.2% efficient, compared to a Conventional Panel on same-sized arrays (370 W mono PERC, 19% efficient, approx. 2 m²)

And more power means more savings.

Meet SunPower Maxeon Cells

No grid lines

SunPower Maxeon cells use back-contact conductivity, eliminating unsightly metal gridlines, and enabling them to absorb more sunlight.

 

Solid metal backing

Metal adds massive strength to each cell, helping it resist corrosion from the elements, while making the entire panel more durable.

 

Thick connectors

Expanding and contracting from daily temperature swings are no problem with our built-in strain relief and thick, triple-redundant connectors.

Frequently Asked Questions

How do SunPower Maxeon solar panels differ from Conventional Panels?

SunPower Maxeon panels provide 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..

SunPower Maxeon panels lead the solar industry in panel efficiency and deliver more bill savings by generating the most solar power and long-term solar energy in a given amount of roof space. That means they generate more power in the same space than all other panels on the market. In fact, the SunPower Maxeon 3 panel was the first 400 watt solar panel in European and Australian home solar, where most Conventional Panels are rated for 280 – 310 watts.

Over time, the advantage grows, because SunPower Maxeon panels also have the lowest degradation rate in the solar industry. While most Conventional Panels tend to degrade around 0.75%/year, SunPower Maxeon panels have proven to degrade at less than one-third of that rate, or about 0.2%/year2Jordan, et al, “Robust PV Degradation Methodology Application” PVSC 2018 and “Compendium of Photovoltaic Degradation Rates” PiP 2016.. To translate into real results – that means a SunPower Maxeon panel delivers up to 25% more energy in its first year of operation. In year 25, that advantage grows to about 45% more energy, for an average of 35% more energy during the first 25 years3SunPower 450 W, 22.2% efficient, compared to a Conventional Panel on same-sized arrays (370 W mono PERC, 19% efficient, approx. 2 m²).

SunPower Maxeon panels also deliver greater peace of mind, having earned the trust of experts by being more reliable and durable—and 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 power warranty promises no more than a 0.25%/ year power drop – the strongest power warranty in solar4Based on Oct. 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 Maxeon panels have been returned under warranty5"A Comparative Study: SunPower DC Solar Module Warranty Claim Rate vs. Conventional Panels." SunPower Corporation. 2019.Lastly, SunPower Maxeon panels are built with our customers in mind, which means higher sustainability standards and more elegant design aesthetics than Conventional Panels. SunPower Maxeon panels have pioneered sustainability efforts in solar manufacturing, and have been recognized with the prestigious Cradle to Cradle Certified™ designation for direct current (DC) panels. The Cradle to Cradle designation demonstrates the products' quality based on rankings of material health, material reutilization, renewable energy use, water stewardship, and social fairness.

SunPower Maxeon panels were also the first and only solar panel to disclose its ingredients through the Declare label – available for all Maxeon 2 and 3 panels. In March 2020, our Mexicali, Mexico manufacturing facility was re-certified by NSF Sustainability as Zero Waste to Landfill – and remains the only solar panel manufacturing facility to achieve this. The certification means that this facility diverts more than 99% of its waste, with 1% or less going to landfills.

The back-contact cell design of SunPower Maxeon panels also delivers an uncluttered and elegant design aesthetic – with panels available in black and white backsheets. This has made SunPower Maxeon panels 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 SunPower Maxeon panel advantage begins with its cell. The SunPower Maxeon cell is a 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 Maxeon 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 up to 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 450 W, 22.2% efficient, compared to a Conventional Panel on same-sized arrays (370 W mono PERC, 19% efficient, approx. 2 m²) 2 SunPower Module 40-year Useful Life. SunPower whitepaper. 2013. SunPower Maxeon solar panels are predicted to 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 SunPower 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.
