Frequently Asked Questions About Solar Panels in Graiguenamanagh
How much do solar panels cost in Graiguenamanagh?
A 4kWp system in Graiguenamanagh 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 3,620 kWh/year, paying for itself in 4-6 years.
Are solar panels worth it in Graiguenamanagh?
Yes. With estimated savings of €946+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Graiguenamanagh pays for itself in 4-6 years and lasts 25+ years.
How does shading affect solar panels in Graiguenamanagh?
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 Microgeneration Support Scheme?
The Microgeneration Support Scheme allows homeowners to sell surplus solar electricity back to the grid at 15-25c/kWh. You need a smart meter (free from ESB Networks) and a grid-connected system. The first €400/year of export income is tax-free.
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 much electricity will solar panels generate in Graiguenamanagh?
Based on Kilkenny county data, a 4kWp system in Graiguenamanagh generates approximately 3,620 kWh per year, covering 75% of average household use (4,200 kWh/year). Kilkenny receives around 1,360 sunshine hours annually.
What roof direction is best for solar panels in Graiguenamanagh?
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.
