1. Solar panel cleaning, photoelectric conversion efficiency test and maintenance;
2. Maintenance of steel support;
3. Maintenance of solar inverter;
4. Equipment wiring and grounding inspection;
5. Solar panel cleaning and solar panel maintenance procedures;
6. Check the color of the solar cell of the photovoltaic panel, the wiring connection, the template, the molded glass and the frame for looseness and damage, and clean it regularly for half a month. The relevant situation should be recorded in the maintenance/repair log. If damaged, replace it immediately or plan to replace it;
7. The surface of the photovoltaic panel can be cleaned every time, which can increase the power generation of the system. According to the actual situation of the site, the cleaning frequency can be appropriately increased.
The maintenance content of the steel bracket is mainly to see whether the steel bracket is rusty.
