Your solar questions for Dunkerrin
How much do solar panels cost in Dunkerrin?

Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in Ireland. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.
What roof direction is best for solar panels in Dunkerrin?
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.
What size solar system do I need for my home in Dunkerrin?
Most homes in Dunkerrin benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 73% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
How long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the ESB Networks notification (NC6 form).
Is my roof suitable for solar panels in Dunkerrin?
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.
Do solar panels work in winter in Offaly?
Yes, solar panels generate electricity all year round. While output is lower in winter, Offaly still receives usable daylight hours even in December. Annual generation figures (3,524 kWh for a 4kWp system) already account for seasonal variation.
