Photovoltaic panel module cleaning is an important part of maintaining and improving the efficiency of solar power generation, and the following is my summary of the precautions for photovoltaic panel module cleaning:
Frequency selection: According to the actual situation and environmental conditions of the photovoltaic panel module, select the appropriate cleaning frequency. In general, if the PV panel modules are exposed to a highly polluted environment, such as an industrial area or desert area, it is recommended to clean them once a month; In relatively clean areas, such as rural or peri-urban areas, it is sufficient to clean them once a quarter.
Cleaning water quality: When cleaning photovoltaic panel modules, use purified or deionized water, and avoid water sources containing sediments, salts or other chemicals. This can reduce the corrosion of the surface of the PV panel module by the cleaning residue and improve the cleaning effect.
Cleaning tools: Choose appropriate tools for cleaning, such as soft sponges or fine-bristled brushes, to avoid scratches or damage to the surface of the PV panel components. At the same time, the cleaning tools should be replaced regularly to avoid secondary pollution of the photovoltaic panel components caused by impurities accumulated on the surface of the tools.
Cleaning method: When cleaning photovoltaic panel modules, it should be carried out in a gentle way to avoid excessive force. You can first wet it with a soft cloth or sponge, gently wipe the surface of the PV panel module, and then use cleaning water to wash it thoroughly. During the cleaning process, care should be taken to avoid cleaning water entering the junction box or other sealing parts of the photovoltaic panel module to prevent the occurrence of electrical faults.
Cleaning time: In order to avoid the rapid evaporation of water at high temperatures, it is recommended to choose to wash in the morning or evening. This ensures that the cleaning water fully wets the surface of the PV panel module and improves the cleaning effect.
Safety measures: When cleaning photovoltaic panel modules, it is important to pay attention to personal safety. Avoid washing at heights to avoid accidental falls. At the same time, it is necessary to ensure that the electrical part will not be touched during the cleaning process to prevent electric shock accidents.
In summary, PV panel module cleaning is an important step to maintain the efficiency of solar power generation. The correct selection of cleaning frequency, cleaning water quality and cleaning tools, and the use of appropriate cleaning methods and time can effectively improve the cleaning effect of photovoltaic panel components, so as to ensure the stable operation and efficient power generation of the solar power generation system.
