1. conversion efficiency, can also be used in low light conditions: This solar panel uses monocrystalline silicon, which can achieve a power generation efficiency of over 21%. Ordinary solar chargers are less efficient at generating power in low light environments. This solar panel uses a unique material that can generate power even at night or in low light conditions. 2. Durability: This solar charger offers a safety factor. Built in anti diodes automatically detect connected devices and charge quickly with current. This prevents overheating, over current, and overcharging. 3. Flexibility: As it is semi flexible, the panel is flexible and can be bent. It can be bent up to 30 degrees. Can be installed on curved surfaces! 4. Waterproof/corrosion resistant: The surface of the solar panel is made of tempered glass, and the frame is made of aluminum. Thanks to the use of waterproof and corrosion resistant materials, it is resistant to disasters such as temperatures, strong wind, and snow. Continuous and stable power generation even in harsh environments.
