Solar Panel FAQs for Legga
How much do solar panels cost in Legga?
A 4kWp system in Legga 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 3,416 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.
What happens to my solar panels if I move house in Legga?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. The SEAI grant does not need to be repaid if you sell. Your installer can transfer monitoring accounts to the new owner.
How much electricity will solar panels generate in Legga?
Based on Longford county data, a 4kWp system in Legga generates approximately 3,416 kWh per year, covering 71% of average household use (4,200 kWh/year). Longford receives around 1,285 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 size solar system do I need for my home in Legga?
Most homes in Legga benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 71% 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.
