Long term exposure to outdoor environments, such as dust, debris, and bird droppings, can inevitably adhere to the surface of solar panels, blocking their absorption of sunlight and resulting in a decrease in their power generation efficiency.

So it is important to develop a maintenance habit for solar panels and regularly clean the surface of dust and debris.

The specific methods can be referred to as follows：

Firstly, in terms of time, cleaning should be carried out when the light is weak. Generally, cleaning of solar panels should be carried out when the sunlight conditions are not good, such as in the morning or evening;

Secondly, before cleaning the solar panel, it is necessary to check whether there is any damage to the solar panel, as well as whether its connecting wires and related components are damaged or adhered, in order to prevent electric shock accidents;

Thirdly, do not use hard and sharp tools or corrosive solvents or alkaline organic solvents to wipe the solar panel. Try to choose soft tools such as sponges, cotton towels, etc. to prevent scratches and corrosion of the solar panel;

Fourth: Pay attention to the cleanliness of the details, especially the entire solar panel, especially the corners where dirt is prone to accumulate, to avoid the formation of load resistance caused by local shading, which affects power generation efficiency;

Fifth: Regularly inspect screws for corrosion and rust. If there is unstable installation due to prolonged exposure to wind, sun, or rain, it is necessary to replace them in a timely manner to ensure secure installation.
