Dust adheres to the surface of the panel and can shield, absorb and reflect light, and the shielding effect on the light is the most important effect. The dust particles absorb and shield light in a reflecting mode, absorption of the photovoltaic cell panel to light is affected, and therefore photovoltaic power generation efficiency is affected. Research shows that dust is deposited on the light receiving surface of the battery panel assembly, so that the light transmittance of the surface of the battery panel is reduced; secondly, the incident angle of part of the light rays is changed, and the light rays are unevenly transmitted in the glass cover plate. Studies have shown that under the same conditions, the output power of a cleaned cell plate assembly is at least 5% higher than that of a deposited ash assembly, and the higher the deposited ash amount, the greater the reduction in the output performance of the assembly.

Research shows that the temperature of the solar cell rises by 1 ℃ and the output power drops by about 0.5%. And under the long-term sunshine, the temperature rise speed of the covered part is far higher than that of the uncovered part, so that the temperature is too high and burning-out dark spots occur.
