Most home solar systems need relatively little routine maintenance, but homeowners should check the inverter display or monitoring app regularly for unusual warnings or a sudden drop in output. Keep panels clear of leaves, branches and heavy dirt, although cleaning may not be necessary after regular rain; use a qualified professional for difficult or roof-based work. Arrange an inspection if you notice cracked panels, loose wiring, water damage or persistent performance problems. A licensed solar electrician can check electrical connections and system safety, while the installer or manufacturer can confirm warranty and servicing requirements.
