Your solar questions for Fermoy
How much do solar panels cost in Fermoy?
A 4kWp system in Fermoy 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.
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 long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
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.
How does shading affect solar panels in Fermoy?
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.
Can I get solar panels on an east or west facing roof in Fermoy?
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 roof direction is best for solar panels in Fermoy?
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.
