Your solar questions for Blackrock
How much do solar panels cost in Blackrock?
A 4kWp system in Blackrock 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.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in Ireland. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.
Can I get solar panels on an east or west facing roof in Blackrock?
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.
How much electricity will solar panels generate in Blackrock?
Based on Louth county data, a 4kWp system in Blackrock generates approximately 3,524 kWh per year, covering 73% of average household use (4,200 kWh/year). Louth receives around 1,315 sunshine hours annually.
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 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.
Are solar panels worth it in Blackrock?
Yes. With estimated savings of €914+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Blackrock pays for itself in 4-6 years and lasts 25+ years.
