Solar Panel FAQs for Errill
How much do solar panels cost in Errill?
A 4kWp system in Errill 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 3,552 kWh/year, paying for itself in 4-6 years.
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.
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.
Can I get solar panels on an east or west facing roof in Errill?
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.
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 to my solar panels if I move house in Errill?
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.
What size solar system do I need for my home in Errill?
Most homes in Errill benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 74% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
