Solar Panel Grant Ireland 2026
The SEAI solar PV grant is worth up to €1,800 in 2026. It's worked out on the size of your system: a higher rate for the first 2 kWp and a lower rate up to 4 kWp. Your home must have been built and occupied before 2021, and you need approval before installation.
- Up to €1,800 grant
- Based on system size
- Homes built and occupied before 2021
- 0% VAT on installation
How the solar grant is calculated
| System size | Grant |
|---|---|
| First 2 kWp | €700 per kWp (up to €1,400) |
| 2 to 4 kWp | €200 per kWp (up to €400) |
| Maximum | €1,800 for a 4 kWp system or larger |
Batteries aren't grant-aided, but many people add one to store daytime solar power for the evening.

What will I actually pay?
A typical home solar system in Dublin costs about €6,000–€12,000 before the grant, depending on size and whether you add a battery. Installation of solar panels on homes currently carries 0% VAT. After the €1,800 grant, most households pay roughly €4,200–€10,200.
Mistakes to avoid: installing before approval, choosing a system too small to use the full grant, and not checking your roof's orientation and shading.
