What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
What is a BER assessment and do I need one?
