Most Australian solar panels need only occasional maintenance, as rain removes much of the dust and debris. Check the system’s monitoring app regularly and look for unusual drops in generation, visible damage, heavy dirt, leaves or shading from growing trees. If cleaning is needed, use a qualified professional, particularly for panels on a steep or high roof, and avoid walking on the panels. Have electrical faults, loose wiring or inverter warnings assessed by a licensed electrician. Check your installer’s maintenance advice and warranty conditions before arranging work.
