Solar panels generally need little maintenance, but check your monitoring app or inverter regularly for sudden drops in generation, warning lights or error messages. Keep panels clear of leaves, branches and heavy dirt; gentle cleaning with water may help, but avoid abrasive products, pressure washers and walking on the roof. Arrange an inspection by a licensed solar electrician if you notice damaged panels, loose wiring, unusual sounds or reduced output that does not have an obvious cause. Follow the manufacturer’s guidance and keep records of servicing for warranty and insurance purposes.
