Photovoltaic solar panels primarily generate electricity by absorbing solar energy and converting it into electrical energy. Cleaning as necessary can ensure the surface cleanliness of photovoltaic panels, which is conducive to absorbing as much sunlight as possible, thereby ensuring electricity generation. If components accumulate dust for a long time, not only will power generation be lost, but serious hot spot effects will occur, leading to reduced component life or even damage. Therefore, it is recommended to pay attention to the cleanliness of the components. and clean them appropriately to ensure electricity production.
Develop a reasonable cleaning schedule based on overall local conditions to ensure a scientific and effective cycle cleaning plan to meet efficiency requirements.acity of electricity production.
2. Cleaning must be clean and thorough. If dead corners are left, this can lead to serious consequences such as a “hot spot effect”.
Under normal lighting conditions, battery panels in corners that have not been cleaned will change from power producing units to power consuming units. Shaded photovoltaic cells will become load resistors that do not generate electricity, consuming energy. power generated by the connected batteries, i.e. heat, which is the hot spot effect. This process will worsen the aging of battery panels, reduce power, and in severe cases can cause fires.
3. Use a special cleaning fluid. Some users use regular tap water or well water to wash and clean solar panels. Since water containsIf there are many impurities, these will adhere to the surface of the glass panels of the battery components, thereby reducing the efficiency of solar power generation. Experiments showed that using tap water to wash battery panels would reduce power generation efficiency by more than 1.8% compared to using a special cleaning fluid .
4. Choose the appropriate cleaning tools and methods to increase the life of the battery board. The surface of the solar cells is made of high-strength tempered glass, which also suffers from wear. The lifespan of solar panels is more than 20 years. To ensure normal electricity production, they generally need to be cleaned once or twice a year. month. If the methods and tools used are inappropriate, it is easy to cause wear of the battery surface, affecting the power generation capacityand battery panel life.
5. Solve the problem of cleaning solar photovoltaic power plants in winter and snow season. Battery components cannot be cleaned with water during winter and snow season. In some seasons there is a problem with condensation and freezing of battery panels. Equipment with snow removal, snow removal, ice melting and waterless cleaning functions must be used. .
