Founded in 1985, Silicon Valley – SunPower is a company with more than three decades of experience innovating in technology, designing and manufacturing the best solar products and solutions worldwide. We’re invested in creating a strong dealer network that delivers solar solutions that help home and business owners save money and live more sustainability – providing a cleaner brighter future for tomorrow.
Our solar panels produce 60% more energy in lesser space than any other conventional solar panel. We’re so confident in the quality of our products, we back them up with our Complete Confidence Warranty, a 25-year warranty for product and performance, all serviced by one company, providing unambiguous coverage. We back up our warranty with rock solid reliability and conservative accounting, providing peace of mind that your investment is covered.
SunPower has a team of highly trained, safety-focused, product and sales experts who exist to help you become better at anything solar. We believe that as we invest in you or your company, we will grow a more sustainable business model.
Rounding out top reasons to work with SunPower is the peace of mind consumers and dealers get when they choose SunPower, one of the largest residential solar brands in the United States and the No. 1 U.S. Commercial Solar Provider. We’ve seen a lot in our almost 35 years in business and have more than 1,000 global patents to prove our commitment to investing and innovating in the solar industry. With a Global footprint, we have powered homes to entire city power plants.
SunPower expects its modules (panels) have a useful life of more than 40-years. This is made possible through fundamental design differences which provide robust protection against real-world stresses. These differences are discussed in the context of comparative experimental data. In addition, SunPower’s physics-based model, PVLife, provides the expected change in performance over time from major degradation and failure modes. Collectively, these data suggest that a 40-year life is realistic useful life for SunPower modules.
Robust State-of-the-Art Technology
SunPower panels are manufactures made of robust shingled cells and advanced encapsulant which are highly resistant to thermal stresses, humidity, and PID. Our panels are operable between temperatures ranging from -40°C – +85°C
The unique parallel circuitry mitigates hotspots and increases energy production in shade or soiling. We use thin screen-printed metal lines in comparison to conventional soldered ribbons along the length of the cell – one of the major failure modes of using traditional cells has been designed out of the panel. Minimal whitespace and no ribbons maximize its efficiency, in return lowering balance of systems costs and increasing the cell flexibility. Our cells are connected across their length, creating many redundant paths for electricity, and no single point of failure; limiting power loss from cracks.
SunPower takes a holistic design view for its modules materials, selecting top quality materials from a select list of extensively qualified partners, delivering world class reliability.
SunPower Performance Series Panels use a unique bussing design to limit power loss from shade when used in landscape, maximizing production during morning and evening row-to-row shading (or dirty conditions).
This also permits closer row spacing, increasing energy density on the roof and lowering installation costs.
Complete Confidence Warranty
The Only Solar Warranty To Cover Your Complete System For 25 Years
SunPower Corporation is so confident in the quality of our products, we back them up with our Complete Confidence Warranty, a 25-year warranty for product and performance, all serviced by one company, providing unambiguous coverage. We back up our warranty with rock solid reliability and conservative accounting, providing peace of mind that your investment is covered.
Sunpower P3 Commercial Series Panels
Sunpower P3 Commercial Series Panels are the highest efficiency commercial solar panels with efficiency up to 20.1% – highest among all commercial solar panels in the world. They have enhanced active area and mono PERC cells which optimize the power density, while lowering system costs.
These panels provide up to 27% more energy in the same space over 25 years. Their unique parallel circuitry maximizes energy production during morning and evening row-to-row shading, or when panels become soiled.
