Housing from Census 2022, as shares of households that answered. Ratings from 25,554 BER certificates for existing Donegal homes built before 2011, leaving out the BERs done for grant claims. Output from the EU's PVGIS satellite record, panels at 35°.

BER ratings in Donegal

A post-works BER is needed to claim the grant, with no set rating to reach. On SEAI's register, 54% of Donegal's existing homes are C or better already, 9th of the 26 counties, and 25% are E, F or G. Panels improve a BER. There's no set rating to reach for the grant, and insulation lifts it further, with its own SEAI grants.

Who can apply in Donegal

73% of households in Co. Donegal own their home, 11th of the 26 counties. The grant goes to the owner, so if you rent, it's the landlord who would apply. 4% live in a flat or apartment, where panels on a shared roof need the management company's agreement.

Owners of homes built and occupied before 2025, with an MPRN. SEAI can't have supported solar PV at that address before, a BER assessor rates the home after the panels go in, and you must use an SEAI-registered solar company and have the grant offer before work starts.

What panels make in Donegal

A south roof in Letterkenny makes about 823 kWh a year for each kWp of panels, 25th of the 26 county towns we checked. So the 2kWp the base grant covers makes about 1,645 kWh a year there: 208 kWh in June and 37 in December.

Grant uptake in Donegal

SEAI's register lists 2,163 BERs done in Co. Donegal in 2025 for grant claims, across all SEAI home grants, not just solar. It's a rough measure of how busy the grant schemes are locally, not a count of solar installs.

The grant, by system size

System	Panels, about	Grant, no battery	Panel grant with a battery	Total with a battery

SEAI's grant rules and its own 2kWp, 3kWp and 4kWp examples. Panel counts above 2kWp scale SEAI's "6/7 panels" for 2kWp; panel sizes vary.

No. Works must not start before you get SEAI's grant offer. Sign with an installer, apply, wait for the offer, then the panels go up. Start first and you lose the grant.

Questions people ask

How much is the solar panel grant in Donegal?

The same as everywhere: €1,400 for 2kWp, up to €1,800 for the panels plus €600 for a battery.

Do homes in Donegal qualify on age?

Almost all do: SEAI's grant is for homes built and occupied before 2025, and Census 2022 counts Donegal's homes up to 2022.

Does my Donegal home need a good BER?

No set rating is needed; a post-works BER records the result. 54% of Donegal's existing homes already rate C or better.

Is this site SEAI?

No. solarpanelgrant.ie is not SEAI or a government body and does not award grants. We pass your request to one SEAI-registered solar installer who covers your area. You apply to SEAI yourself, or the installer helps you; SEAI decides and pays the grant.
