Solar Panel FAQs for Killargue
How much do solar panels cost in Killargue?
A 4kWp system in Killargue 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 3,368 kWh/year, paying for itself in 4-6 years.
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 Killargue?
Based on Leitrim county data, a 4kWp system in Killargue generates approximately 3,368 kWh per year, covering 68% of average household use (4,200 kWh/year). Leitrim receives around 1,150 sunshine hours annually.
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.
What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect ESB workers). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
Do solar panels work in winter in Leitrim?
Yes, solar panels generate electricity all year round. While output is lower in winter, Leitrim still receives usable daylight hours even in December. Annual generation figures (3,368 kWh for a 4kWp system) already account for seasonal variation.
