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.

Most homes in Peterswell benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 70% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
How do I get the SEAI grant in Peterswell?
Apply online at seai.ie with your MPRN and Eircode. Use an SEAI-registered installer. Do not start work before your Letter of Offer. After installation, complete a BER assessment. The grant is paid to your bank within 4-6 weeks.
How does shading affect solar panels in Peterswell?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
Are solar panels worth it in Peterswell?
Yes. With estimated savings of €881+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Peterswell pays for itself in 4-6 years and lasts 25+ 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.
