Frequently Asked Questions About Solar Panels in Carrigart
How much do solar panels cost in Carrigart?
A 4kWp system in Carrigart 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 solar panels work in winter in Donegal?
Yes, solar panels generate electricity all year round. While output is lower in winter, Donegal still receives usable daylight hours even in December. Annual generation figures (3,268 kWh for a 4kWp system) already account for seasonal variation.
Can I get solar panels on an east or west facing roof in Carrigart?
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.
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 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.
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 much electricity will solar panels generate in Carrigart?
Based on Donegal county data, a 4kWp system in Carrigart generates approximately 3,268 kWh per year, covering 68% of average household use (4,200 kWh/year). Donegal receives around 1,175 sunshine hours annually.
