Most home solar systems need only occasional maintenance, but it is sensible to check the panels, inverter and monitoring app every few months. Look for heavy dirt, leaves, bird droppings, shading, damaged cables or warning lights, and arrange professional cleaning if buildup is affecting sunlight. Do not climb onto the roof or handle electrical components yourself; a licensed solar electrician should inspect faults, unusual performance or storm damage. Keep records of generation and follow the maintenance and warranty guidance from your installer or manufacturer.
