Frequently Asked Questions About Solar Panels in Deansgrange
How much do solar panels cost in Deansgrange?
A 4kWp system in Deansgrange 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 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.
Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid. ESB Networks installs smart meters for free. Your installer submits the NC6 form to ESB Networks after installation, which triggers the meter upgrade if needed.
What happens to my solar panels if I move house in Deansgrange?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. The SEAI grant does not need to be repaid if you sell. Your installer can transfer monitoring accounts to the new owner.
How do I get the SEAI grant in Deansgrange?
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.
Can I get solar panels on an east or west facing roof in Deansgrange?
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 long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the ESB Networks notification (NC6 form).
