25-YEAR LIFETIME WARRANTY
The Most Complete Warranty in Solar, Guaranteed.
1 Solar holds the world record for the highest efficiency solar panels, with output production guaranteed at 92% of original production in year 25, compared to 80% for conventional panels. Our monitoring ensures that in the unlikely event a panel under-performs, we diagnose any issue, then service the panel for free.
1 Solar panels are designed in America and built to last, with an unbeatable 25-Year Lifetime Warranty covering 100% of repair or replacement costs including labor and shipping, no questions asked. However, as only 1-in-20,000 1 Solar panels fail, you'll probably never have to use it.
1 Solar can guarantee the quality of our workmanship because we do not subcontract any step of the installation. We have an in-house staff of NABCEP-certified installation crews and licensed elecricians, along with a full-time service department, enabling us to offer the most complete warranty in the industry.
