Your solar questions for Cornamona
How much do solar panels cost in Cornamona?
A 4kWp system in Cornamona 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 3,544 kWh/year, paying for itself in 4-6 years.
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.
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.
Is my roof suitable for solar panels in Cornamona?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
Are solar panels worth it in Cornamona?
Yes. With estimated savings of €910+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Cornamona pays for itself in 4-6 years and lasts 25+ 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.
What is the payback period for solar panels in Cornamona?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €910+ per year plus export income, a typical solar system in Cornamona pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
