What are the maintenance skills for household photovoltaic power plants?
Household photovoltaic power station, also known as household solar power generation system, mainly refers to the solar system installed on the roof of the home. Residential power stations generally have the characteristics of small installed capacity, wide distribution, simple grid connection process, short investment payback period, and high subsidies. The main components of household photovoltaic power plants are: photovoltaic panels, inverters, meters, and solar brackets, among which solar panels and inverters are the core components of the entire system.
1. Maintenance skills of household photovoltaic power plants
1. Users should check and record regularly. Once a problem is found, contact the after-sales service personnel in time.
2. Regularly clean up dust and other sundries. In summer, you should avoid cleaning the panel when the temperature is the highest, so as to avoid damage to the photovoltaic modules due to thermal expansion and contraction. It is recommended to clean solar panels in the early morning or late afternoon when the temperature is cooler.
3. Use a soft and clean cotton cloth or sponge as a cleaning tool. Do not use detergents containing alkali or acid. The frequency of cleaning depends on the situation. If it is in the rainy season, the rain will generally make the surface of the panel cleaner.
4. In areas that are prone to snow in winter, the frequency of cleaning should be increased. It is recommended to clean the panel before the snow is too thick. If there is heavy snow on the panel, use a soft tool to push it away, being careful not to scratch or damage the panel.
5. The distributed photovoltaic power generation system is equipped with a lightning protection device, so there is no need to cut off the power during thunderstorms in summer. However, for the sake of safety, you can also cut off the circuit connection with the photovoltaic module to avoid the danger caused by direct lightning strikes, which cannot be avoided by lightning protection devices.
6. Do not install other household equipment near the power generation system, so as not to damage the system or affect power generation.
Please note:
Do not step on the photovoltaic panel during inspection to avoid damage. It is forbidden to place flammable and explosive dangerous goods near photovoltaic modules. If the following problems occur, please contact a professional to repair the photovoltaic system immediately:
● Photovoltaic modules have broken glass, burned circuits, and obvious color changes.
● The junction box in the photovoltaic module is deformed, cracked, burned or the connection terminal cannot be connected.
2. Maintenance of solar bracket
1. The prefabricated base of the solar support should be placed flat and tidy before installation, and the position should not be moved. All connections of the bracket should be firm and reliable, and all bolts should be fixed correctly.
2. Cracks or peeling off on the surface of the stent coating should be brushed or repaired in time.
3. The grounding device of the solar power generation system should be checked regularly, especially before the annual thunderstorm season, the grounding of the solar power system should be checked to confirm its safety.
The above is the relevant content about the maintenance skills of household photovoltaic power plants shared today. Regular and timely cleaning and maintenance can ensure the normal operation and safe use of household photovoltaic power plants and avoid unnecessary property losses.
