Solar panel grant: €1,800, 19% of a typical semi-detached job
SEAI pays €1,800 toward solar panels on a semi-detached house (SEAI, read 7 September 2026). SEAI's median price for that job in the first half of 2026 was €9,500, so the grant covers 19%. It is the same for every type of home. The grant has to be approved before any work starts.

SEAI's grant against SEAI's median price for the job, the first half of 2026. SEAI rule
The solar panels grant covers 19% of a typical semi-D job
Against SEAI’s median costs, grants cover up to 87% of a heat pump and 82% of cavity wall insulation, but 23% of heating controls and 19% of solar panels.
Each bar is the job's median cost for a semi-D (SEAI, January to June 2026); the filled part is the grant on the individual route. Heat pump: €10,500 for the unit, €2,000 for the heating system and, since 29 Sep 2026, a €2,000 boiler scrappage grant: €14,500 of €16,741, or 75% without the scrappage grant, which needs an oil, gas, solid-fuel or storage-heating system removed.

Four things SEAI asks for, in its own words
Our plain version first, then SEAI's sentence as we read it. SEAI decides each application, not us. SEAI rule
The home was built and lived in before 2025 (before 2021 until 6 October 2026). SEAI rule
“The house must have been built and occupied before 2025.”

The home has had no solar panel grant before. SEAI rule
“The grant is not open to homes with previous funding for solar PV at this MPRN.”

The home has an energy rating (BER). SEAI rule
“The Applicant must have a Building Energy Rating (BER) assessment of their home”

The grant is approved before any work starts. SEAI rule
“You must have grant approval in place before you start work.”

Approval takes minutes. Payment takes 4–6 weeks
Every SEAI grant runs the same six steps, and nothing starts before the offer. SEAI rule
Approval takes minutes and payment 4–6 weeks; the wait in between isn't published
SEAI publishes minutes from online application to offer, 30 days to accept, 8 months to finish and claim, and 4–6 weeks to pay. It publishes nothing for the assess, works or claim steps.
The six steps of the do-it-yourself grant route, in order. Under each step is the timing SEAI publishes, or a dashed box where it publishes none; we read every SEAI page, the terms and the homeowner guides on 8 Sep 2026. The 8-month window runs from the offer to the claim (One Stop Shop route: 12 months). Nothing starts before the offer. Work or materials paid for before it lose the grant. The marked step is the one this page is about: apply.
