Regular care keeps output near expectation and catches faults early.
Cleaning basics Use soft tools, clean water and cool panels. Avoid abrasives, harsh chemicals and pressure jets. Do not walk on panels. See panel cleaning.
Frequency Dusty dry months need more frequent cleaning. Watch your generation trend; a gradual dip often means soiling.
Inspection checklist - Loose or damaged mounting parts - Cable insulation and connectors - Inverter display or error codes - Shadows from new structures or growth - Bird nesting under panels
Monitoring Compare daily generation against similar clear days. Sudden drops suggest faults and need a repair visit.
Safety DC cables stay live in sunlight. Work near wiring should be done by qualified people. Consider an AMC.
FAQ ### Do panels need servicing each year? A yearly inspection is common practice. ### Does rain clean panels? It helps but may leave streaks; stubborn dirt needs cleaning.
