Key benefits conversion efficiency: Monocrystalline silicon cells convert 19.8% to 21% of sunlight into electricity, delivering reliable power for off grid and mobile applications. Prevents battery drain: The junction box includes a builtin diode to block reverse current and prevent battery discharge at night. Flexible mounting: The panel bends up to 30 degrees for installation on curved or uneven surfaces, expanding placement options. Lightweight and durable: At 2.5 mm thickness and made from advanced polymer materials, the panel is easy to carry and resistant to heat, UV exposure, water, rain, snow, and extreme temperatures. Complete connectivity and protection: Each panel features six copper mounting holes (10 mm diameter), a 0.9 m waterproof positive and negative photovoltaic connector, a 1 m extension cord, a 2in1 plug, and a 40 A solar controller to protect the battery during charging. Features and specifications Cell type: Monocrystalline silicon Conversion efficiency: 19.8% to 21% Flexibility: Up to 30 degrees bend Thickness: 2.5 mm Mounting: Six copper grommet holes, 10 mm diameter Connectors and cables: 0.9 m waterproof PV positive and negative connector, 1 m extension cord, 2in1 plug Controller: 40 A solar controller included Materials: Advanced polymer construction for lightweight durability Environmental tolerance: Heat resistant, UV resistant, water resistant, able to withstand rain, snow, and extreme temperatures Junction box: Builtin diode to prevent reverse charging and battery leakage Why this panel solves common problems Converts sunlight efficiently to reduce dependence on shore power or generators when camping, boating, or traveling. Flexible design allows mounting on curved surfaces where rigid panels will not fit. Robust materials and waterproof connectors minimize maintenance and extend service life in outdoor conditions. Integrated diode and included 40 A controller help maintain battery health by preventing reverse discharge and regulating charging. Typical applications Marine use: Install on sailboat or yacht decks and cabin roofs to keep house batteries charged for navigation electronics, lighting, and pumps. Camping and RV: Mount on tent canopies, camper roofs, or awnings to power lights, small appliances, and battery systems while off grid. Vehicle and small property installations: Attach to car roofs, tiny houses, garden sheds, or remote outbuildings for supplemental power where space and weight are limited. Installation notes Mounting options include adhesive and screws; grommets at the corners make it simple to secure with bolts or straps. Use the included 0.9 m waterproof connector, 1 m extension cord, and 2in1 plug for straightforward wiring to the 40 A controller and battery. Ensure the panel is positioned to receive maximum sunlight and avoid prolonged shading for performance.
