First opening their doors in Silicon Valley, California way back in 1985, SunPower have gained a reputation as one of the most experienced and long-established solar technology companies active today.
Not only do they hold the record for most efficient solar modules, they’ve also laid claim to over 200 patents for solar technology, staking their claim as a world leader in residential, commercial and even utility-scale solar power production.
They are proud to back their products, and do so confidently with a 25-year product and power warranty. So, in the unlikely case that something does go wrong, they are happy to assist by repairing or replacing faulty panels as necessary in the very rare case of non-performance. However, this is rarely an issue, as their panels are renowned for being some of the most robust and hardy panels available on the market.
