Common Questions About Going Solar in Legan
How much do solar panels cost in Legan?
A 4.4 kWp system in Legan typically costs €8,300–€9,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €6,500–€7,200. The system generates approximately 3,416 kWh/year, paying for itself in 4-6 years.
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 €1025+ 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 payback period for solar panels in Legan?
With a net cost of €6,500–€7,200 after the SEAI grant and savings of €1025+ per year plus export income, a typical solar system in Legan pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
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 size solar system do I need for my home in Legan?
Most homes in Legan benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 81% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
Can you go off-grid with solar in Legan?
Fully off-grid setups are rare in Legan. Most homes stay grid-connected and sell surplus back through the Microgeneration Support Scheme. A hybrid inverter with 10-20 kWh of battery storage covers evenings and power cuts, which is what most people searching "off-grid" actually want. A true off-grid system needs a much larger array and battery bank, and you lose the grant-supported export income.
