What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect ESB workers). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
Do solar panels work in winter in Mayo?
Yes, solar panels generate electricity all year round. While output is lower in winter, Mayo still receives usable daylight hours even in December. Annual generation figures (3,364 kWh for a 4kWp system) already account for seasonal variation.
How much electricity will solar panels generate in Ballaghaderreen?
Based on Mayo county data, a 4kWp system in Ballaghaderreen generates approximately 3,364 kWh per year, covering 71% of average household use (4,200 kWh/year). Mayo receives around 1,105 sunshine hours annually.
Can I add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost €3,000-€6,000 and are not yet covered by the SEAI grant.
What roof direction is best for solar panels in Ballaghaderreen?
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.
Is my roof suitable for solar panels in Ballaghaderreen?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
