260 Watt Shade-Tolerant Flexible Solar Panel – SunPower A+ Grade 24.4% Efficiency
Take your off-grid power to the next level with the 260W Shade-Tolerant Flexible Solar Panel, built with premium SunPower A+ grade Maxeon cells (24.4% efficiency) for the highest performance in the industry. Designed for marine, RV, and van applications, this powerful panel ensures maximum output - even in shaded conditions.
Unlike standard panels, the 260W design is divided into four independent quadrants, so if one section is shaded by a mast, boom, or rooftop fixture, the other three keep generating full power. This makes it an ideal choice for sailboats, yachts, camper vans, RVs, and off-grid systems where shadows are unavoidable. Video on them Here.
Engineered for durability and flexibility, this semi-flexible solar panel is perfect for canvas biminis, dodgers, van roofs, and curved surfaces. For best results, mount between support bars to prevent stress on the solar cells.
