Do I need to clean my solar panels?

Can I sell excess solar electricity?

How much electricity will solar panels generate in Mountrath?

Can I get solar panels on an east or west facing roof in Mountrath?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
What is a BER assessment and do I need one?
A Building Energy Rating (BER) assessment is required after installing solar panels to claim the SEAI grant. A BER assessor visits your home and rates its energy efficiency from A1 to G. Solar panels typically improve your BER by 1-2 grades. The assessment costs around €150-€200.
