Housing from Census 2022, as shares of households that answered. Ratings from 80,343 BER certificates for existing Cork 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 Cork

A post-works BER is needed to claim the grant, with no set rating to reach. On SEAI's register, 54% of Cork's existing homes are C or better already, 8th of the 26 counties, and 27% 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 Cork

69% of households in Co. Cork own their home, 21st of the 26 counties. The grant goes to the owner, so if you rent, it's the landlord who would apply. 10% 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 Cork

A south roof in Cork makes about 978 kWh a year for each kWp of panels, 3rd of the 26 county towns we checked. So the 2kWp the base grant covers makes about 1,955 kWh a year there: 242 kWh in June and 63 in December.

Grant uptake in Cork

SEAI's register lists 6,966 BERs done in Co. Cork 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 Cork?

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

Do homes in Cork qualify on age?

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

Does my Cork home need a good BER?

No set rating is needed; a post-works BER records the result. 54% of Cork'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.
