Common Questions About Going Solar in Mullahoran
How much do solar panels cost in Mullahoran?
A 4kWp system in Mullahoran 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 3,364 kWh/year, paying for itself in 4-6 years.
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.
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 is the payback period for solar panels in Mullahoran?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €899+ per year plus export income, a typical solar system in Mullahoran pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
