SEAI Solar Grant 2026: Everything You Need to Know

What is the SEAI solar PV grant?

The SEAI (Sustainable Energy Authority of Ireland) offers a grant of up to €1,800 for solar photovoltaic (PV) panels for homes. This grant is available through the Better Energy Homes scheme for homes built and occupied before 2025. The grant covers systems up to 4 kWp in size, which is sufficient for most Irish homes. From 5pm on 6 October 2026, eligible homeowners on certain Department of Social Protection payments can get €8,400 for solar panels up to 4 kWp plus €600 for a 5 kWh battery, up to €9,000 in total.

0% VAT on solar panels

Since May 2023, solar panels have been zero-rated for VAT in Ireland. This means you pay no VAT on the supply and installation of solar PV systems. On a typical home installation costing €8,000–€12,000, this saves between €900 and €1,400 — on top of the SEAI grant. The 0% VAT applies regardless of the grant and is automatic: your installer should not be charging VAT on a standard home solar installation.

Who is eligible?

To qualify for the SEAI solar grant you must:

• Own and occupy the property as your primary home
• Have a home built and occupied before 2025
• Not have previously claimed a solar PV grant at the same electricity meter (MPRN)
• Use an SEAI-registered contractor to carry out the work
• Apply for grant approval before work begins — not after

How to apply

Applications are made through the SEAI Better Energy Homes online system at seai.ie. You apply before work starts, receive approval, have the work done by a registered contractor, and then claim payment. The whole process typically takes 4–8 weeks from application to payment. Your contractor can often handle the paperwork on your behalf.
