1. Cleaning of photovoltaic modules varies depending on different regions and different weather conditions.
1. In areas where it rains a lot, cleaning is usually not necessary. When it rains, it will have automatic cleaning effect, such as in Jiangsu, Zhejiang and Shanghai.
2. In areas with less rain, it is recommended to clean once a month during non-rainy seasons. In areas with heavy rainfall, the number of cleanings should be increased appropriately depending on the dust accumulated on the ground. sign.
3. At present, most photovoltaic power plants are equipped with the function of online monitoring of power generation. The cleaning time can also be selected based on its monitoring data. been considerably lower recently, cleaning time may be accelerated.
2. Preguarantees for cleaning components:
1. Correct cleaning method: Cleaning time should be carried out after sunset as much as possible. When cleaning, you should try to use compressed air or water to rinse and then wipe it with a lint-free cloth.
2. Precautions for cleaning components: When cleaning, you should try not to use cleaning agents or other cleaning liquids containing active substances such as additives. Make sure not to use relatively hard and rough materials as the components. currently used in China There is an “anti-reflective film” on the front of the glass of most modules. This film will fall off after repeated friction with hard objects. When it falls, it will affect the power generation capacity of the power supply. station and also affect the self-cleaning effect of the module.
