The Sustainable Energy Authority of Ireland tops your install with a cash grant. We submit the application, track approval, coordinate BER inspection, and apply the grant to your invoice. You never see a form.
€800/kWp up to €1,800. A 4 kWp install earns the full grant, no portal to learn.
0% VAT on domestic solar. The 2023 government scheme saves another 13.5% off the gross install cost.
BER inspection coordinated. SEAI requires a post-install assessment; we book the inspector and submit the result.
Smart Export Guarantee. Excess power pays you ~€0.21/kWh; we register the meter for you.
In their words
Homeowners and operators on working with MarVal.
"A transformative journey towards sustainability. Our partnership enables guests to enjoy luxurious hospitality knowing their stay is powered by renewable energy."
"144 panels, 19.85 tonnes of CO₂ avoided every year, and a SEAI grant we'd have never figured out on our own. The MarVal team carried it."
"A proven track record in delivering commercial-scale energy technology. From planning through construction and operation, highly organised and efficient."
"A 5-star heritage estate is a tough brief. They designed a 66 kWp install that's almost invisible from the visitor approach. Discreet and effective."
FAQs
The questions most homeowners ask before they call. If yours isn't here, the phone number above gets you a real person.
Do I qualify for the €1,800 SEAI grant?
Most owner-occupied homes built before December 2020 qualify. The home must have an existing BER cert (or get one done as part of the install, we book it). Rental properties currently don't qualify for the residential grant, though landlords have a separate (smaller) scheme. We confirm eligibility on the survey call.
How much will my electricity bill drop?
For an average 3-bed Irish home with a 4 kWp system: roughly €900–€1,400 a year, depending on your usage pattern and how much sun you get. Bills that previously sat around €2,200/yr commonly drop to €1,000–€1,100. We'll model your specific case in the quote.
How long does the install take?
Most domestic installs are 1–2 days on site. Scaffold up day one, panels and inverter live by end of day two. Power switchover is a 10-minute outage. Total time from sign-off to commissioning is typically 4–6 weeks (the longest pole is ESB connection notice).
Will it lift my BER rating?
Almost always, yes, typically by one or two bands. A 4 kWp system often takes a C2-rated home into the B band, which is the threshold most banks use for green mortgage rates. We coordinate the post-install BER assessor as standard.
What happens to extra power I don't use?
It goes back to the grid and your supplier pays you for it under the Smart Export Guarantee, currently around €0.21/kWh. We register your meter on completion so the credits start landing on your next bill.
What if a panel breaks in year 12?
Same number you called for the install. Manufacturer panel warranty is up to 30 years, our workmanship guarantee is 5 years, and our monitoring catches most underperformance before you notice it. No third-party maintenance contract to chase.
Do I need planning permission?
Almost never. As of 2022, domestic rooftop solar is fully exempt from planning permission in Ireland regardless of the system size, provided the panels stay within the roof outline. Protected structures and conservation areas are the exceptions; we'll flag them on the survey.
