Frequently Asked Questions About Solar Panels in Annagassan
How much do solar panels cost in Annagassan?
A 4kWp system in Annagassan 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.
Are solar panels worth it in Annagassan?
Yes. With estimated savings of €958+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Annagassan pays for itself in 4-6 years and lasts 25+ years.
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.
What roof direction is best for solar panels in Annagassan?
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.
Can I add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost €3,000-€6,000 and are not yet covered by the SEAI grant.
What is the Microgeneration Support Scheme?
The Microgeneration Support Scheme allows homeowners to sell surplus solar electricity back to the grid at 15-25c/kWh. You need a smart meter (free from ESB Networks) and a grid-connected system. The first €400/year of export income is tax-free.
Is my roof suitable for solar panels in Annagassan?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
