Common Questions About Going Solar in Legan
How much do solar panels cost in Legan?

Can I sell excess solar electricity?
Yes. Under Ireland's Microgeneration Support Scheme, you sell surplus electricity at 15-25c/kWh. You need a smart meter (ESB Networks installs free). The first €400/year of export income is tax-free.
Are solar panels worth it in Legan?
Yes. With estimated savings of €917+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Legan pays for itself in 4-6 years and lasts 25+ years.
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 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.

Most homes in Legan benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 73% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
