Frequently Asked Questions About Solar Panels in Walsh Island
How much do solar panels cost in Walsh Island?
A 4kWp system in Walsh Island 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 3,524 kWh/year, paying for itself in 4-6 years.
What is a BER assessment and do I need one?
A Building Energy Rating (BER) assessment is required after installing solar panels to claim the SEAI grant. A BER assessor visits your home and rates its energy efficiency from A1 to G. Solar panels typically improve your BER by 1-2 grades. The assessment costs around €150-€200.
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 roof direction is best for solar panels in Walsh Island?
South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in Ireland.
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 Walsh Island?
Yes. With estimated savings of €929+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Walsh Island pays for itself in 4-6 years and lasts 25+ years.
Can I get solar panels on an east or west facing roof in Walsh Island?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
