What roof direction is best for solar panels in Ballynahinch?
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 the UK.
Can I sell excess solar electricity?
Yes. Under the UK's Smart Export Guarantee (SEG), you can sell surplus electricity at 3-15p/kWh. You need a smart meter and an MCS-certified installation. Your energy supplier pays you for every unit exported to the grid.
Can I get solar panels on an east or west facing roof in Ballynahinch?
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 happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect engineers working on the grid). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
