325 Watt Shade Tolerant Flexible Solar Panel with Polycarbonate & J-Mount Brackets - Sunpower A+ Grade 24.4% Efficient Cells

325 Watt Shade Tolerant Flexible Solar Panel with Polycarbonate & J-Mount Brackets - Sunpower A+ Grade 24.4% Efficient Cells Take your off-grid power further with the 325W Shade-Tolerant Flexible Solar Panel, built with premium SunPower A+ grade Maxeon cells delivering up to 24.4% efficiency - among the highest in the industry. Designed specifically for marine and van applications, this panel provides exceptional output even in challenging, partially shaded environments. Unlike conventional panels, this 325W design is engineered with a multi-section cell layout that helps maintain power production when part of the panel is shaded. Whether it’s a mast, boom, AC unit, or roof vent casting a shadow, the panel continues generating power where others would drop off significantly. Video on them here. Built for real-world installations, this semi-flexible panel conforms to gentle curves, making it ideal for: Biminis and dodgers Van roofs Boat decks and cabin tops Curved surfaces The low-profile, lightweight construction reduces wind resistance and eliminates the need for bulky mounting hardware, perfect for clean, efficient installs. Installation Note: For best performance and longevity, mount the panel on a stable surface or between support bars to prevent stress on the solar cells. ✅ Solar panel kit includes: PV solar panel module Sheet of twin wall polycarbonate backing Two J channel mounting extrusions Owner’s Manual 📦 Ships Next Day UPS Ground from Denver or Michigan.
