Frequently Asked Questions About Solar Panels in Kilkenny City
How much do solar panels cost in Kilkenny City?
A 4kWp system in Kilkenny City 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.
Do solar panels work in winter in Kilkenny?
Yes, solar panels generate electricity all year round. While output is lower in winter, Kilkenny still receives usable daylight hours even in December. Annual generation figures (3,620 kWh for a 4kWp system) already account for seasonal variation.
What size solar system do I need for my home in Kilkenny City?
Most homes in Kilkenny City benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 76% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
What is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most Irish homes, solar PV is the better investment: it's more versatile, qualifies for the SEAI grant, and you can sell excess electricity. Solar thermal only heats water.
Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid. ESB Networks installs smart meters for free. Your installer submits the NC6 form to ESB Networks after installation, which triggers the meter upgrade if needed.
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.
How does shading affect solar panels in Kilkenny City?
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.
