Delvin solar panel questions answered
How much do solar panels cost in Delvin?
A 4.4 kWp system in Delvin typically costs €8,300–€9,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €6,500–€7,200. The system generates approximately 3,484 kWh/year, paying for itself in 4-6 years.
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.
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 happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect ESB workers). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
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.
Can you go off-grid with solar in Delvin?
Fully off-grid setups are rare in Delvin. Most homes stay grid-connected and sell surplus back through the Microgeneration Support Scheme. A hybrid inverter with 10-20 kWh of battery storage covers evenings and power cuts, which is what most people searching "off-grid" actually want. A true off-grid system needs a much larger array and battery bank, and you lose the grant-supported export income.
