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 20134 SunPower 0.25%/yr degradation vs. 1.0%/yr conv. panel. Campeau, Z. et al “SunPower Test Report” NREL, Q1-20155 “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)

Unmatched reliability 9

SunPower offers the best Combined Power and Product Warranty
