Solar panels are generally low maintenance, but check your monitoring app or inverter display regularly for unusual drops in energy production or fault messages. Keep an eye out for heavy dirt, leaves, bird droppings, shading and visible damage, particularly after storms; cleaning may help when build-up is affecting output. Avoid climbing onto the roof or using harsh chemicals, and have cleaning, electrical checks or repairs carried out by a suitably qualified professional. Follow the maintenance guidance from your installer and contact them or a licensed electrician if the system shows persistent faults.
