The maintenance requirements of the solar panel system are not high, but they exist. It not only involves solar photovoltaic panels and solar panel supports, but also solar inverters, cables and batteries when necessary. The maintenance requirements for solar photovoltaic panels are relatively small. There are no "rotating parts", which reduces the maintenance required for solar photovoltaic panels.

          Solar photovoltaic panels are always exposed to the weather. Therefore, it must be checked regularly. The purpose of this inspection is to check the sealing and integrity of the solar photovoltaic panel, whether it is dirty, the tension in the attachment, and the formation of "hot spots".

          A solar inverter is a component that is not as strong as a solar photovoltaic panel. Compared with modules with a shorter life cycle, photovoltaic inverters reflect higher requirements for their maintenance. In addition, the software of the photovoltaic inverter should be updated regularly. The maintenance of the photovoltaic inverter also includes checking the connectors on the DC side and the AC side.

           If the power meter belongs to the equipment operator, it must be calibrated regularly. However, if the power feed meter is the property of the grid operator, maintenance and calibration are within their scope of responsibility.

           The photovoltaic support system is an important safety measure for solar photovoltaic power generation systems. Therefore, its visual inspection should be performed at least every six months. Under high wind loads, the fixing devices or screw connections on the photovoltaic installation system may also loosen, thereby endangering the safety of the entire power plant.
