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.
Do solar panels work in winter in Wexford?
Yes, solar panels generate electricity all year round. While output is lower in winter, Wexford still receives usable daylight hours even in December. Annual generation figures (3,860 kWh for a 4kWp system) already account for seasonal variation.
What size solar system do I need for my home in Fethard-on-Sea?
Most homes in Fethard-on-Sea benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 83% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
How does shading affect solar panels in Fethard-on-Sea?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
