1. Module Warranty: 25-year limited warranty of 85% power output; 12-year limited warranty of 93% power output; 5-year limited warranty of
materials and workmanship. See your local representative for full terms of these warranties.
2. This data represents the performance of typical BP modules, and are based on measurements made in accordance with ASTM E1036
corrected to SRC (STC.)
3. During the stabilization process that occurs during the first few months of deployment, module power may decrease by approx. 1% from
typical P
