A residential photovoltaic power station mainly consists of four parts: photovoltaic modules (photovoltaic panels), inverters, meter boxes, and mounting brackets. Among them, modules and inverters are the core components of the entire system.
Routine maintenance of residential photovoltaic power stations
1. Users should conduct regular inspections and keep records of these inspections. If any problems are found, they should contact after-sales service personnel immediately.
2. Clean the modules promptly when dust or debris is found. In summer, avoid cleaning during the hottest times of day to prevent damage from thermal expansion and contraction. It is recommended to clean in the early morning or late evening when temperatures are lower. Use soft, clean cotton cloths or sponges for cleaning; never use alkaline or acidic cleaning agents. The frequency of cleaning depends on the situation. During the rainy season, rainwater generally keeps the module surface relatively clean.
3. In areas prone to snow accumulation in winter, cleaning frequency should be increased. It is not recommended to clean only when the snow is too thick. If there is a thick layer of snow on the components, please use a soft tool to push it away, being careful not to scratch the solar panels.
4. Distributed photovoltaic power generation systems are equipped with lightning protection devices, so they do not need to be disconnected during summer thunderstorms. However, for safety reasons, the circuit connection to the photovoltaic modules can be cut off to avoid damage from direct lightning strikes that the lightning protection module cannot eliminate.
5. Do not install range hoods or exhaust fans near the power generation system to avoid damaging the system or affecting power generation.
Maintenance considerations for residential photovoltaic power stations
1. Do not step on the photovoltaic modules during inspection to avoid damage. Flammable and explosive materials must not be placed near the photovoltaic modules. If the following problems are found, please immediately contact a professional or after-sales service for adjustment or replacement of the photovoltaic modules;
(1) Photovoltaic modules exhibit issues such as broken glass, burned backsheets, and noticeable color changes;
(2) The photovoltaic modules have issues such as deformed, cracked, or burned junction boxes, or inability to connect the terminals;
2. Maintenance of the support frame
(1) For photovoltaic brackets installed on prefabricated bases, the prefabricated bases should be placed stably and neatly, and their positions should not be moved. All bracket connections should be firm and reliable, and all bolts should be complete.
(2) If the anti-corrosion and anti-rust coating on the surface of the bracket cracks or peels off, it should be reapplied in time.
(3) The bracket should be properly grounded. In particular, the grounding system should be inspected before the annual rainy season to check whether the connection is firm and the contact is good.
The normal and smooth operation of a residential photovoltaic power station depends on scientific maintenance. Regular and timely cleaning and maintenance are essential to ensure the normal operation and safe use of the station and to avoid unnecessary property losses.
