Solar cell maintenance. The lighting surface of the solar photovoltaic cell array should always be kept clean. If there is dust or other dirt on the daylighting surface, rinse it with clean water first, and then gently wipe off the water stains with a clean gauze. Do not wipe with hard objects or rinse with corrosive solvents.

The junction box of solar modules should be regularly inspected to avoid aging. The packaging and wiring connectors of solar cell components should be inspected quarterly, such as water ingress into the packaging plastic, discoloration of the battery, loose, disconnected, corroded connectors, etc., and should be cleaned in a timely manner.
