Grants for domestic solar panels in Ireland are capped at €1,800 in 2026, plus €600 for a battery, or up to €9,000 for qualifying welfare recipients.
This is the first time in years where the maximum SEAI grant value for solar panels was not reduced by €300, and where there’s a grant available for a battery.
The chart below shows the maximum grant value for solar panels and battery, combined, in Ireland from 2023 to 2026.
Continue reading to see the grant value breakdown by system size and year.
Plus, you’ll also get a solar PV grant calculator that’ll help you easily find the grant value applicable to you.
But first, just in case grant values start dropping again next year, here’s how you can lock in the higher 2026 grant value.
The maximum grant for solar panels in Ireland, in 2026, is €1,800, plus €600 grant for a 5kWh+ battery, or up to €9,000 for qualifying welfare recipients.
The grant value is lower for solar systems smaller than 4kWp.
For the standard solar panel grant, there’s an €700 grant per kWp up to a 2kWp system, and an additional €200 for every extra kWp installed up to 4kWp.
While the solar panel grant values have stayed the same this year, there’s a longer trend of reducing values.
To lock in the higher 2026 grant values, you must complete and submit your solar PV grant application before January 1st 2027.
Once approved, you and your installer have 8 months to complete the install and submit the declaration of works.
If the 8-month deadline is missed, then the grant will expire and be declined.
You’ll then lose the 2026 grant rate. Any reapplication afterwards will fall under 2027 grant rates, or later, when the planned grant reductions are expected to continue again.
Use the solar panel grant calculator below to see how much the grant value is in 2026 for various solar PV sizes.

As mentioned, SEAI grants for solar panels are capped at €1,800 in 2026. There’s a €700 grant per kWp up to 2kWp, and there’s an additional €200 for every additional kWp (up to 4kWp). This is the same as 2025, which is the first time in years that solar panel grants haven’t dropped.
But, in late 2026, a new €600 flat rate grant for a 5kWh+ battery was introduced.
The combined standard solar and battery grants brings the total available grants to €2,400.
However, also introduced in late 2026, was an enhanced grant (up to €9,000 for a solar and battery system) for eligible homeowners in receipt of certain Department of Social Protection payments.
Grants for solar panels in 2025 were capped at €1,800.
Solar installations that were 4kWp or more were eligible for the full grant value. Smaller installations were eligible for lower grant values.
In 2025, there was a €700 grant per kWp up to a 2kWp system. And there was an additional €200 for every additional kWp up to a 4kWp system.
The table below displays the key solar grant values and compares them with the values from previous years.
This table lists the solar panel grants from 2023 to 2026 for various system sizes:
| Solar PV system size | 2023 solar grants | 2024 solar grants | 2025 solar grants | 2026 solar grants |
| 1kWp | €900 | €800 | €700 | €700 (+€600 for battery) |
| 2kWp | €1,800 | €1,600 | €1,400 | €1,400 (+€600 for battery) |
| 3kWp | €2,100 | €1,850 | €1,600 | €1,600 (+€600 for battery) |
| 4kWp+ | €2,400 | €2,100 | €1,800 | €1,800 (+€600 for battery) |
The SEAI notes: “the grant is paid on a pro rate basis e.g. for a 2.5kWp system the grant value would be €1,500.”
The maximum solar panel grant dropped from €2,400 in 2023, to €2,100 in 2024 and then to €1,800 in 2025 and 2026.
This capped grant value was expected to decrease annually but the drop was paused in 2026.
From 2023 to 2024, there was a grant reduction of €100 per kWp up to 2kWp, dropping from €900 to €800. 2025 saw the same reduction, coming in at €700, which remains in 2026.
In 2024, there was a €50 drop in the grant value for every extra kWp above 2kWp (and below the capped 4kWp grant value), falling from €300 in 2023 to €250 in 2024. There was another €50 drop in 2025 resulting in a grant value of €200, which is the same in 2026.
The grants for the various system sizes are expected to drop every year as planned, with the freeze in 2026 being a nice surprise for many.
Another nice surprise in 2026 was the additional €600 flat rate grant for a 5kWh (or larger) battery.
To ensure you don’t miss the higher grant values, you must get your relevant grant approval before any scheduled reduction dates.
To find the relevant grant value, you must first know what solar system size best suits you.

At Ohk energy, we believe in the power of community and giving back. That’s why, when we teamed up with Leinster and Ireland back-row star Caelan Doris, we saw an opportunity to make a real difference. To celebrate our partnership with Caelan, we launched the Power a Brighter Future campaign, raising vital funds for Childline by ISPCC.
From August 6th, 2024, to September 6th, 2024, we pledged €50 from every sale of solar PV systems and air-to-water heat pumps to Childline, an organisation dedicated to supporting vulnerable children across Ireland.
Thanks to the support of our customers and community, we are proud to announce that we raised over €16,300 for this incredible cause.">
