What Innishannon homeowners ask about solar
How much do solar panels cost in Innishannon?
A 4kWp system in Innishannon typically costs €5,000-€8,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €3,200-€6,200. The system generates approximately 3,628 kWh/year, paying for itself in 4-6 years.
What size solar system do I need for my home in Innishannon?
Most homes in Innishannon benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 79% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
Can I get solar panels on an east or west facing roof in Innishannon?
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.
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).
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.
How does shading affect solar panels in Innishannon?
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.
What is the payback period for solar panels in Innishannon?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €998+ per year plus export income, a typical solar system in Innishannon pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
