Balgriffin solar panel questions answered
How much do solar panels cost in Balgriffin?

How long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the ESB Networks notification (NC6 form).
What happens to my solar panels if I move house in Balgriffin?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. The SEAI grant does not need to be repaid if you sell. Your installer can transfer monitoring accounts to the new owner.
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.
