Frequently Asked Questions About Solar Panels in Donnybrook
How much do solar panels cost in Donnybrook?
A 4kWp system in Donnybrook 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 happens to my solar panels if I move house in Donnybrook?
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.
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.
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 Microgeneration Support Scheme?
The Microgeneration Support Scheme allows homeowners to sell surplus solar electricity back to the grid at 15-25c/kWh. You need a smart meter (free from ESB Networks) and a grid-connected system. The first €400/year of export income is tax-free.
Do I need planning permission for solar panels?
Most residential solar installations are exempt from planning permission, provided panels don't project more than 15cm from the roof and don't cover more than 50% of total roof area.
Do solar panels work in winter in Dublin?
Yes, solar panels generate electricity all year round. While output is lower in winter, Dublin still receives usable daylight hours even in December. Annual generation figures (3,660 kWh for a 4kWp system) already account for seasonal variation.
