What Dublin 8 homeowners ask about solar
How much do solar panels cost in Dublin 8?
A 4kWp system in Dublin 8 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 3,660 kWh/year, paying for itself in 4-6 years.
What roof direction is best for solar panels in Dublin 8?
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.
How much electricity will solar panels generate in Dublin 8?
Based on Dublin county data, a 4kWp system in Dublin 8 generates approximately 3,660 kWh per year, covering 76% of average household use (4,200 kWh/year). Dublin receives around 1,500 sunshine hours annually.
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 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 payback period for solar panels in Dublin 8?
With a net cost of €3,200-€6,200 after the SEAI grant and savings of €955+ per year plus export income, a typical solar system in Dublin 8 pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
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.
