Solar Panel FAQs for Arigna
How much do solar panels cost in Arigna?
A 4.4 kWp system in Arigna typically costs €8,300–€9,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €6,500–€7,200. The system generates approximately 3,468 kWh/year, paying for itself in 4-6 years.
What is the payback period for solar panels in Arigna?
With a net cost of €6,500–€7,200 after the SEAI grant and savings of €1040+ per year plus export income, a typical solar system in Arigna pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
Do solar panels work in winter in Roscommon?
Yes, solar panels generate electricity all year round. While output is lower in winter, Roscommon still receives usable daylight hours even in December. Annual generation figures (3,468 kWh for a 4kWp system) already account for seasonal variation.
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 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.
What roof direction is best for solar panels in Arigna?
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 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 you go off-grid with solar in Arigna?
Fully off-grid setups are rare in Arigna. Most homes stay grid-connected and sell surplus back through the Microgeneration Support Scheme. A hybrid inverter with 10-20 kWh of battery storage covers evenings and power cuts, which is what most people searching "off-grid" actually want. A true off-grid system needs a much larger array and battery bank, and you lose the grant-supported export income.
