What Longwood homeowners ask about solar
How much do solar panels cost in Longwood?
A 4kWp system in Longwood 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 3,540 kWh/year, paying for itself in 4-6 years.
How does shading affect solar panels in Longwood?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
How do I get the SEAI grant in Longwood?
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.
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.
What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
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.
Are solar panels worth it in Longwood?
Yes. With estimated savings of €930+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Longwood pays for itself in 4-6 years and lasts 25+ years.
