What to expect when investing in SunPower Panels?

SunPower holds the record for the highest efficiency silicon solar panel, which means you can create more power, on smaller roof spaces, with fewer panels (or leave more roof space free for future expansion).
Industry Leading Warranty
SunPower pioneered the solar industry with the first 25-year combined Power and Product Warranty. Unlike most solar warranties that cover just the panels, SunPower’s warranty also covers transport and labour costs to uninstall and re-install the panels. This makes Sunpower one of the safest, long-term solar power investments.
