After the installation of a solar energy storage and generation system, it is inevitable that there will be such situations: dust, fallen leaves, bird droppings, etc. Piled up on the module surface, it has a great impact on the energy generation of the solar energy storage and generation system. Therefore, it is necessary to regularly clean the solar panels of the solar energy storage and generation system. According to industry statistics, regular cleaning of photovoltaic solar panels can effectively increase electricity generation by about 8% per year.

So, how to clean photovoltaic solar panels? How often is it appropriate to clean them? What are the tools for cleaning photovoltaic boards? , Follow the roof solar energy storage and generation system of the solar energy storage and generation system Xiaobian to understand it!

At present, owners of solar panels of family solar energy storage and generation systems can clean them by themselves. If there is no special situation, there is no need to spend money to find a professional maintenance team.

Tools for cleaning solar panels are also common, such as high-pressure water guns, soft brushes, cotton mops, etc. These tools are low in cost and easy to use.

When cleaning, if there is only a small amount of dust on the surface of the solar panel, just use a high-pressure water gun to flush it.

If there are particles such as sand and soil on the surface, use a high-pressure water gun to flush it off, then use a soft brush to brush it off to avoid particles sticking to the electric board.

If there are sticky pollutants such as bird droppings and oil stains on the surface, wipe them off with a clean cloth, rinse with glass water, and then rinse them off with a water gun.

It should be noted that when using a high-pressure water gun, pay attention to the pressure of the water gun. Too high water pressure may damage the solar panel.

What should be paid attention to when cleaning solar panels?

(1) It is better to choose to clean in the early morning, evening or night, avoiding high temperature periods such as noon, so as not to damage the solar panel.

(2) When cleaning, pay attention to avoid using hard and sharp objects to directly contact the solar panel.

(3) Do not step on the solar panel, bracket and other components, which may damage the power station and affect the service life.

According to the current industry operation and maintenance experience, in winter and other snow and rain seasons, it can be cleaned once a month (such as snow should be cleaned in time), and other months can be cleaned twice a month. For wind and sand areas, it depends on the specific situation.

Note: Try not to use soapy water when cleaning components. Generally, when we use soap to wash our hands, our hands will leave a thin film. Similarly, after washing the components with soap, a thin film or residue will be left on the surface of the photovoltaic components, which will promote the faster attachment and accumulation of dust, etc., affecting the power generation of the power station. In addition, it is not easy to use other corrosive cleaning agents.
