Problems solved by technology

[0008] Existing solar power panels, after a period of use, are easily corroded by bad weather such as rain, dust, etc., affecting power generation efficiency, reducing service life, and increasing maintenance costs
Through the retrieval of existing patent documents, it is found that the utility model patent of CN201420538506 discloses a solar panel coating device, which is to put the solar panel into the paste polyvinyl chloride resin liquid for coating; however, its light transmission is not good , affecting the power generation efficiency
[0009] In addition, the sun’s light is strongest at noon, and the power generation effect is the best in theory, but in actual use, the sun’s light will also bring about a temperature rise, and the temperature rise is not good for photovoltaic power generation, and the voltage will drop accordingly. At the same time, the resistance in the circuit will increase, which will also affect the current and cause the hot spot effect
