We are relentless in our quest to bring the most innovative and highest quality solar solutions to every market, and to do it all sustainably No other solar company offers such a complete package MORE INNOVATIVE 500+ PATENTS Our quest to bring the abundance of the sun to as many households and businesses drives us to continually innovate HIGHEST EFFICIENCY SunPower makes the highest efficiency solar panels you can buy for your roof 7 SunPower panels deliver 38% more power than a Conventional Panel 8 Highest energy production 1 30% more energy under real-world conditions compared to a Conventional Panel 2 High year one performance delivers 7-9% more energy per rated watt 3 This advantage increases over time, producing 20% more energy over the first 25 years to meet your needs 4 Delivers excellent performance in real world conditions, such as high temperatures, clouds and low light 4,5 SunPower panels maintain their energy production much better than conventional panels in partly-shaded conditions 6 HIGHEST PRODUCTION 1 1% more energy than E-Series, which was most energy per rated watt out of 151 panels tested. Photon International, Feb 2013. 2 PVEvolution Labs “SunPower Shading Study,” Feb 2013. Compared to a Conventional Panel (240W, 15% efficient, approx. 1.6 m2) 3 Typically 7-9% more energy per watt. BEW/DNV Engineering “Sunpower Yield Report” Jan 2013 4 SunPower 0.25%/yr degradation vs. 1.0%/yr conv. panel. Campeau, Z. et al “SunPower Test Report” NREL, Q1-2015 5 “SunPower Module 40-Year Useful Life” SunPower white paper, May 2015. Useful life is 99 out of 100 panels operating at more than 70% of rated power. 6 PVEvolution Labs “SunPower Shading Study,” Feb 2013. Compared to a Conventional Panel (240W, 15% efficient, approx. 1.6 m2) 7 Highest of over 3,200 silicon solar panels, Photon Module Survey, Feb 2014. 8 SunPower 345W panel vs. Conventional Panel (250W, 15.3% efficient, approx. 1.6 m2)
