South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in Ireland.
Can I get solar panels on an east or west facing roof in Coolock?
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.
Do solar panels work in winter in Dublin?
Yes, solar panels generate electricity all year round. While output is lower in winter, Dublin still receives usable daylight hours even in December. Annual generation figures (3,660 kWh for a 4kWp system) already account for seasonal variation.
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.
