【Excellent performance】: Using high-quality monocrystalline silicon cells, covering the high reflectivity ETFE layer, the conversion rate is high, as long as there is sunlight, it can continue to supply power. High-efficiency monocrystalline silicon solar cells provide good performance even in low light conditions. 【Waterproof and High Temperature Resistance】: The solar panel can still work after rain and can withstand extreme wind and snow loads of 2400 Pa and 5400 Pa. Waterproof, high temperature resistant and easy to clean. Flexible solar panels that can be bent up to 30 degrees. 【High Quality Material】: Using the latest component packaging technology, it is thinner, lighter, softer and more durable. Multi-layer laminations improve battery performance and provide longer service life. The panel has a 6-hole design, which can be fixed on different types of surfaces and has better compatibility. 【Function】: Solar panels can convert light energy into electrical energy, which can effectively deal with problems such as power shortage and power failure. Using solar panels is a great option for places where electricity is unavailable or out of reach. 【Scope of application】: This solar panel is recommended to be used with the controller and battery. Perfect for RVs, boats, sails, yachts, trucks, cars, coaches, cabins, RVs, tents, trailers, golf carts or any other uneven surface.
