With the widespread use of solar panel cleaning brushes and photovoltaic cleaning robots, many people know that photovoltaic equipment needs to be cleaned regularly. Do you know why the cleaning of photovoltaic equipment is so important?

For long-running photovoltaic power generation systems, the impact of panel dust on it should not be underestimated. The dust on the surface of the panel has the function of reflecting, scattering and absorbing solar radiation, which will reduce the transmittance of the sun, resulting in a decrease in the solar radiation received by the panel, and the output power will also decrease. Its effect is proportional to the cumulative thickness of the dust.

In addition to affecting the solar radiation absorption of the panel, dust also affects the photovoltaic module, which becomes the thermal insulation layer of the module, the service life of the junction box and the solar panel. When the junction box and the battery panel are in a high temperature state for a long time, it is easy to produce a high temperature of more than 100 degrees, and it will cause a short circuit in the serious.

In addition to the impact of dust on photovoltaic equipment, glass panels are also susceptible to acid and alkali corrosion products. In some areas with acidic rainfall, photovoltaic glass panels are easily corroded by rain and form corrosion marks on the surface. The glass panel corroded by rainwater is prone to diffuse reflection, which affects the spread uniformity of solar radiation. Therefore, it is very important to clean the solar panels regularly to reduce losses.
