BEIJIAYI 1000W Solar Panel Kit 2PCS 500W, Flexible Solar Panel Off Grid System 18V Photovoltaic Monocrystalline Module, with Dual USB Ports

【Material】Solar panels use ETFE. ETFE material has higher light transmittance and longer service life than ordinary materials. ETFE material guarantees optimum performance day in and day out. The backplane adopts TPT, which has good heat dissipation, waterproof, high temperature resistance and easy cleaning. [Safe and efficient] The conversion rate of monocrystalline silicon solar panels can reach 19.8%~21%. The junction box has a built-in diode, which can reverse charge the battery to prevent leakage at night. It can effectively convert light energy into electric energy, realize safe power supply, energy saving and environmental protection. It also performs well in extreme lighting conditions. 【High conversion efficiency, can also be used in low light environment】This solar panel adopts monocrystalline silicon, which can achieve high power generation efficiency of more than 21%. Ordinary solar chargers are less efficient at generating electricity in low-light environments. This solar panel uses a unique material to generate electricity even at night or in low-light environments. 【You will get】2pcs flexible solar panel 500W 18V 40A solar controller, 2m cable with PV connector, 1m cable with alligator clip, 2-in-1 adapter, user manual and friendly customer service. 【Semi-Flexible】Plastic back panel can be bent up to a maximum of 30 degree arc and can be installed on RV, boat, cabin, tent, car, truck, trailer or any other uneven surface. With good walkability, it is suitable for areas without electricity and inconvenient urban traffic., Weight: 4.40924524 Pounds, Manufacturer: BEIJIAYI
