Solar in Mayo: 14 questions answered
How much is the SEAI solar panel grant for a home in Mayo?
SEAI pays €700 per kWp for the first 2kWp and €200 per extra kWp up to 4kWp, capped at €1,800 for solar panels.
Can I apply for the SEAI solar grant after the panels are fitted?
No. You must apply to SEAI and have your formal letter of offer in hand before any installation work starts on your roof.
What VAT rate applies to home solar panels in Ireland?
Solar panels supplied and installed on private homes qualify for a 0% VAT rate.
Does my house age matter for the SEAI Solar PV grant?
Yes. To qualify for the SEAI Solar Electricity Grant, the home must have been built and occupied before 2021 and must not have received an SEAI solar PV grant previously.
What is the ESB Networks NC6 form?
The NC6 microgeneration notification form is submitted to ESB Networks by your registered installer at least 20 working days before the system is commissioned so your smart meter can record exported power.
How does the Clean Export Guarantee (CEG) pay for exported electricity?
Your electricity supplier pays a per-kWh microgeneration export tariff for surplus solar power sent to the grid, and the first €400 a year of microgeneration export income is exempt from income tax.
Do solar panels work on east-facing and west-facing roofs in Ireland?
Yes. An east-west split array generates power earlier in the morning and later into the evening, producing roughly 80 to 85% of the annual kWh of a due-south roof.
Do I need a post-works BER assessment to claim the SEAI grant?
Yes. A registered BER assessor must complete and publish a post-works Building Energy Rating certificate before SEAI releases the grant payment.
What is a hybrid inverter and when do I need one?
A hybrid inverter manages both rooftop solar panels and a home battery, whereas a standard string inverter only converts panel DC power to household AC power.
What does a hot water diverter (such as an Eddi) do?
A solar PV diverter monitors surplus generation and sends spare electricity to your immersion heater to heat your hot water cylinder before exporting to the grid.
Do rooftop solar panels require planning permission in Ireland?
Most domestic rooftop solar installations are exempt from planning permission, provided panels stay at least 50 cm inside the roof edge and project no more than 15 cm above a pitched roof.
How long does it take to fit solar panels on a house?
Most domestic installations take 1 to 2 working days for the roof mounting, panel wiring, inverter setup and testing.
Do solar panels still generate electricity on cloudy days?
Yes. Modern monocrystalline panels generate power from diffuse daylight all year round, though winter output in December and January is lower than in May and June.
