180 Watt Walkable Semi-Rigid Solar Panel - Sunpower A+ Grade 24.4% Efficient Cells

Deliver reliable, high-output solar power with the 180 Watt Walkable Semi-Rigid Solar Panel, designed for marine and RV off-grid applications where space, performance, and durability matter most.
Engineered with SunPower A+ Grade monocrystalline solar cells (24.4% efficiency), this panel delivers superior performance even in partial shade and extreme heat. Its new lightweight fiberglass backing plate design is 3mm thinner than standard walkable panels (4mm vs 7mm), allowing for better heat dissipation and efficiency in hot climates.
Built to withstand the harsh marine environment, this rugged, semi-rigid solar panel can be safely walked on when properly mounted — ideal for boat decks, van roofs, and camper racks. The included Poly and J brackets make installation fast and secure, while the white background reduces heat absorption and maintains a clean, professional look.
Whether you’re cruising the ocean or traveling off-grid in your van, this high-efficiency 180W SunPower panel ensures consistent, quiet, and renewable power wherever you go.
