Can You Get the SEAI Solar Grant on a Holiday Home?

Yes. A holiday home can claim the full €1,800 SEAI Solar Electricity Grant, and claiming on your own house first does not use it up. SEAI runs its eligibility check against the property's meter number, not against you or where you sleep. Two of the other supports behave differently, though, and nobody tells you at quote stage: if you let the place out short-term you lose the 0% VAT rate, and the €400 tax-free allowance on export income applies only at your sole or main residence, so it never covers a second home.

The Grant: SEAI Checks the House, Not the Householder

SEAI's Solar Electricity Grant page sets out who can apply, and the list is about ownership type rather than occupancy. Eligible applicants are “all homeowners, including private landlords”, owner management companies, and Approved Housing Bodies. There is no clause anywhere requiring the house to be your principal private residence, and no question on the application asking how many nights a year you spend there.

What SEAI does test is the property:

• The home needs an MPRN, the 11-digit meter point reference on your electricity bill.
• It must have been built and occupied before 2021.
• The grant is not open to homes with previous funding for solar PV at that MPRN.

A cottage in Kerry that has been in the family since the 1980s clears all three. So does a bungalow you bought as a bolthole in 2019. A new-build holiday lodge finished in 2022 does not, for the same reason any 2022 house does not. That case is covered in our guide to the solar grant on new builds.

Claiming on Your Main Home Does Not Use Up Your Grant

This is the question people actually ring SEAI about. You put panels on your own house two years ago and took the €1,800. Can you do it again on the second place?

You can. The exclusion SEAI publishes is worded “previous funding for solar PV at this MPRN”. It attaches to the meter, not to your name or your PPSN. Two properties are two MPRNs, so the block from the first never reaches the second. The same logic is why a landlord with four eligible rentals can claim four times, and why a grant claimed by a previous owner of your house still blocks you. Our guide on whether you can get an SEAI grant twice works through the once-per-home rules measure by measure.

Before you commit, spend ten minutes proving the second property is clean: phone the SEAI helpdesk on 01 808 2100 with that MPRN and ask which measures have already been funded there. On a house you did not own from new, this matters more than it does on your own home.

What the Grant Actually Pays

The amounts are the same as for any other eligible home, and the maximum stays at €1,800 for 2026:

The process is identical too: an SEAI-registered company, grant approval in writing before any work starts, eight months from approval to finish the job and file the Declaration of Works, and a post-works BER before SEAI will pay. Allow four to six weeks for the money to land. Our application guide walks through each step.

One practical wrinkle on a house you do not live in: your installer must apply to ESB Networks to connect the system, and SEAI says that alone usually takes at least four weeks, or 20 working days. If you are coordinating access to a property three hours away, build that into the plan rather than discovering it in week seven of eight.

The 0% VAT Depends on Whether You Let It Out

Here is the line almost every solar page in Ireland skips. Since 1 May 2023 the zero rate of VAT applies to the supply and installation of solar panels on private dwellings. Revenue's guidance then lists the buildings that are not private dwellings for this purpose, and the list names hotels, B&Bs, guest houses used for short-term accommodation, and a “holiday home used for short term-accommodation”.

So the answer turns on use, not on the label:

When the zero rate is off the table, the job falls back to the reduced rate, but only if the value of the goods does not exceed two-thirds of the contract. On a solar install the panels, inverter and any battery are usually well past that line, which means the 23% standard rate applies to the whole contract. On a €9,000 job that is roughly €1,700 of VAT you would not otherwise have paid. That is more than the grant is worth.

For a genuinely mixed-use property, Revenue allows apportionment, but the contract and invoice have to say so. In Revenue's own worked example a B&B with 10% of its floor space in private residential use gets the zero rate on 10% of the price, with the balance at the reduced rate subject to the two-thirds rule. If that is your situation, get the split written into the contract before signing, not after.

The €400 Tax-Free Export Allowance Does Not Follow You

Sell surplus electricity to the grid from your own home and the first €400 of profit each year is exempt from income tax, USC and PRSI. That exemption comes from section 216D of the Taxes Consolidation Act 1997, and Revenue's manual is specific about where it applies: to electricity generated by an individual “at his or her sole or main residence”, for their own consumption. Revenue adds that you do not have to own the property, and a rented home counts, but you “must use the property as his or her sole or main residence during the tax year”, and you must be named on the electricity bill.

A holiday home is, by definition, not your sole or main residence. The exemption does not reach it. Every euro of export credit the second property earns is taxable, generally under Case IV, and it should go on your return.

Two things worth knowing before that puts you off:

• The payments still arrive. Losing the exemption does not mean losing the Clean Export Guarantee income. Your supplier still credits you for what you export. It is taxed, not withheld.
• You cannot write off the panels. Revenue allows a deduction for incidental running costs, but explicitly no deduction for the capital cost of buying and installing the system, and no capital allowances.

The exemption is worth €400 a year for each year from 2024 to 2028, and Finance Act 2025 extended the scheme to 31 December 2028. Our full guide to tax on solar export income covers how the exemption works where it does apply.

Does Solar on a Holiday Home Add Up?

Be honest with yourself about the shape of the year. The money in solar comes mostly from electricity you use as you generate it, because avoiding a unit you would have bought is worth far more than exporting it. A house occupied six weeks a year gets that backwards: most of what the roof makes in June and July goes straight out to the grid, and the grid is the lower-value customer.

That is the same reason the tax point above stings. On a second home, export is not the leftover — it is the main return, and it is the part with no allowance sitting in front of it.

Three situations where it still works:

• The place is let, and let often. Occupancy is what fixes the maths. A property let through the summer is consuming at exactly the hours the roof is producing. Weigh that against losing the 0% VAT.
• You are heading for full-time use. If it becomes your main residence later, the €400 exemption starts applying from the year it does, and the grant is worth taking while the house still qualifies on the pre-2021 rule.
• There is a big standing load. Frost protection, a dehumidifier running all winter, a heat pump ticking over to keep a coastal house dry. These run whether anyone is there or not.

Before You Get Quotes on a Second Property

1. Confirm the house was built and occupied before 2021.
2. Ring SEAI on 01 808 2100 with that property's MPRN and confirm no solar PV grant has been paid there.
3. Decide, and be able to state, whether the house is let short-term. That is what sets your VAT rate.
4. Budget for the export income being fully taxable, with no €400 shelter.
5. Get grant approval before anyone starts work, and allow for the ESB Networks connection application usually taking at least 20 working days on its own.
