SEAI solar grants explained (2026)

The SEAI grant is one of the biggest reasons Irish homeowners put panels on the roof, and the figures change, so here is exactly where things stand in 2026.

How much is the SEAI solar grant?

The SEAI Solar Electricity Grant is worth up to €1,800*. It is tiered by the size of the system, measured in kWp: €700 per kWp for the first 2 kWp, then €200 per kWp from 2 to 4 kWp, capped at €1,800.

So 2.5 kWp of panels attracts €1,500, and a 4 kWp system reaches the full €1,800 cap. A 3.5 kWp system, which is about eight panels on a 3-bed semi, attracts €1,700.

Is battery storage grant-aided?

Yes, since 6 October 2026. A separate €600* SEAI battery grant covers a battery of 5kWh or larger, alongside the solar grant on your panels. You can apply for both in one SEAI application, and if you already have panels you can apply for the battery grant on its own. The battery is also the part that lets you use what your roof made in the evening, so most homeowners include one.

*SEAI grants are applied for by the homeowner and approved and paid by SEAI. Eligibility, approval and payment are between you and SEAI, and grant amounts are set by SEAI and can change. We'll make sure the paperwork your grant needs is completed.

Who qualifies?

Your home needs to have been built and occupied before 2025, and every grant must be applied for and approved before any work starts. A BER assessment is needed after the install to draw down the grant, and you will need a valid MPRN, which is your meter’s number, printed on your bill. The grant is one per MPRN, so it follows the property rather than you.

How the grant is paid

You apply to SEAI yourself and get your grant approved before any work starts. SEAI pays the grant to you after the work is done, and we take care of the paperwork your grant needs. Your installation qualifies for the SEAI Solar Electricity Grant.
