Solar Panel FAQs for Portsalon
How much do solar panels cost in Portsalon?
A 4kWp system in Portsalon 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 3,268 kWh/year, paying for itself in 4-6 years.
Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid. ESB Networks installs smart meters for free. Your installer submits the NC6 form to ESB Networks after installation, which triggers the meter upgrade if needed.
How do I get the SEAI grant in Portsalon?
Apply online at seai.ie with your MPRN and Eircode. Use an SEAI-registered installer. Do not start work before your Letter of Offer. After installation, complete a BER assessment. The grant is paid to your bank within 4-6 weeks.
Do I need planning permission for solar panels?
Most residential solar installations are exempt from planning permission, provided panels don't project more than 15cm from the roof and don't cover more than 50% of total roof area.
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.
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 Portsalon?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €844+ per year plus export income, a typical solar system in Portsalon pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
