Description

Technical Field

[0002] Photovoltaic panels, also known as solar panels, are devices that use the photoelectric effect to convert solar energy directly into electrical energy. They are mainly composed of semiconductor materials such as silicon. The core function of photovoltaic panels is to convert sunlight energy into electrical energy for daily life or industrial use. The design and manufacture of photovoltaic panels involve a variety of materials and technologies, including but not limited to glass, EVA, TPT backplanes and aluminum alloy frames. Photovoltaic panel cleaning is crucial to ensuring the efficiency of photovoltaic power generation systems. During the operation of photovoltaic panels, dust, dirt and other impurities will gradually accumulate on their surfaces. The presence of these substances will block sunlight from directly shining on the photovoltaic panels, reducing the transmittance and power generation efficiency of the photovoltaic panels. Studies have shown that if there is 5% dirt on the surface of the photovoltaic panel, its power generation efficiency may drop by as much as 20%. In addition, long-term accumulation of dirt may also cause damage to the photovoltaic panel material and shorten its service life.
