Most Australian solar systems need little routine maintenance, but check your monitoring app regularly for sudden drops in generation and arrange a professional inspection if faults appear. Keep panels clear of leaves, bird droppings and heavy dust; cleaning may be useful in some locations, but avoid climbing onto the roof or using abrasive products. Have a licensed electrician or accredited solar professional inspect wiring, isolators, mounting and the inverter when needed, particularly after severe weather. Check your installer and panel or inverter warranty terms, as maintenance requirements can vary by system.
