The SEAI Solar Electricity Grant is €1,800, and Budget 2027 (6 October 2026) announced no cut. The government's stated plan is still to reduce it by up to €300 per year until the scheme ends in 2029, which would mean €1,500 in 2027, but no 2027 rate change has been published — check seai.ie before you apply. The 2026 rate, tier structure, and eligibility rules are confirmed and unchanged for anyone applying now.
This page covers what the 2027 change looks like in numbers, who it affects, and what Budget 2027's no-cut outcome means for anyone currently at the quote or quote-comparison stage.

Current Grant Tiers (2026) vs Expected 2027 Position
The 2026 grant pays €700 per kWp for the first 2 kWp, then €200 per kWp for the next 2 kWp, capping at €1,800 for a 4 kWp or larger system. If the planned €300 reduction proceeds, the most likely adjustment is lower per-kWp rates — the exact 2027 tier structure has not been published. When the grant stepped down from €2,100 to €1,800, both tiers were cut: Tier 1 from €800 to €700 per kWp and Tier 2 from €250 to €200 per kWp.
| Year | Max grant | Tier 1 (first 2 kWp) | Tier 2 (next 2 kWp) | Cap system size |
|---|---|---|---|---|
| 2024 | €2,100 | €800/kWp | €250/kWp | 4 kWp |
| 2025 | €1,800 | €700/kWp | €200/kWp | 4 kWp |
| 2026 | €1,800 | €700/kWp | €200/kWp | 4 kWp |
| 2027 (if cut) | €1,500 (not announced) | Not published | Not published | 4 kWp (no change expected) |
2024 and 2025 rates are confirmed historical figures. 2027 figures reflect the government's stated intention as per Citizens Information (10 March 2026) and were not confirmed in Budget 2027 (6 October 2026), which announced no cut.
The 2026 hold at €1,800 was the first time the grant did not step down year-on-year since the current tier structure was introduced. That holdover was a ministerial decision; the baseline policy direction remains downward.
Eligibility Rules: Unchanged Going Into 2027
The building-age rule changed on 6 October 2026. These are the conditions that apply now:
Built and occupied before 1 January 2025. SEAI asks for the year the home was built and occupied; if you're unsure, ESB Networks can tell you the year it was first connected. Until 6 October 2026 the cut-off was before 2021; homes built or first occupied in 2025 or later are still excluded.
No minimum BER rating required. The B2 minimum was removed in 2022. You don't need a BER to apply, but a post-works BER assessment must be completed after install and published before SEAI pays the grant. No minimum rating is required.
SEAI-registered installer only. You apply via mgen.seai.ie as the homeowner, naming an SEAI-registered solar PV company. A standard RECI or Safe Electric certified electrician whose company is not on the SEAI registered list does not qualify. Check any installer's registration at the SEAI registered installer search before you sign anything.
Republic of Ireland only. Northern Ireland runs a separate scheme. The SEAI grant applies to the 26 counties only.
One grant per property. If a previous owner already claimed the solar electricity grant on your property, a second application will be rejected. Check with SEAI if you are buying a home where solar was already installed.
How the Grant Got to €1,800: The 2024–2026 History
The grant was €2,400 when the current per-kWp tier structure was first introduced, stepped down to €2,100 in 2024, then to €1,800 for 2025 as panel and install costs fell. The plan for 2026 was another €300 reduction to €1,500. That cut was reversed in November 2025 — the government confirmed the 2026 rate would hold at €1,800.
The hold was a one-year exception, not a change in direction. The Citizens Information page (10 March 2026) still states the trajectory is a €300/yr reduction toward a 2029 end date. Solar Energy Ireland (the trade body) welcomed the hold at the time while noting the medium-term direction is still downward.
Budget 2027 (6 October 2026) did not announce the deferred €300 cut, and the government's 29 September package kept the grant at €1,800 while widening eligibility. A cut in 2027 is still the documented intention on Citizens Information, but nothing has been announced.
What a €300 Reduction Means in Real Cost Terms
If the 2027 grant settles at €1,500, here is what that means in net cost for typical system sizes:
| System size | Typical gross cost (2026 market) | 2026 grant | 2026 net cost | 2027 grant (if €300 cut) | 2027 net cost | Difference |
|---|---|---|---|---|---|---|
| 3 kWp | €6,500–€9,000 | €1,600 | €4,900–€7,400 | €1,300 (if cut) | €5,200–€7,700 | +€300 |
| 4 kWp | €8,000–€10,500 | €1,800 | €6,200–€8,700 | €1,500 (if cut) | €6,500–€9,000 | +€300 |
| 5 kWp | €9,000–€11,500 | €1,800 | €7,200–€9,700 | €1,500 (if cut) | €7,500–€10,000 | +€300 |
| 6 kWp | €10,000–€12,500 | €1,800 | €8,200–€10,700 | €1,500 (if cut) | €8,500–€11,000 | +€300 |
Gross cost ranges are mid-market estimates for 2026. Gross costs in 2027 will likely be 3–7% lower as panel and inverter costs continue to fall, which partially offsets the grant reduction. Net cost figures assume no gross cost change for simplicity; see the break-even analysis for the full model including cost deflation.
For a 4 kWp system — the most common residential size in Ireland — the difference is €300 more out of pocket in 2027, before accounting for any fall in panel prices. On a south-facing roof, €300 represents roughly three to four months of electricity savings. Every month you delay is a month you are not generating.
0% VAT on Solar PV: Separate From the Grant, Unaffected
Since 1 May 2023, the supply and installation of solar panels on private dwellings has been zero-rated for VAT in Ireland. It is a permanent measure — not time-limited like the SEAI grant. The 0% rate covers the panels, inverter, and installation labour for a residential customer.
Before May 2023, most residential supply-and-install contracts paid the 13.5% reduced rate (the standard 23% applied only where the panels were more than two-thirds of the contract value), so the VAT saving on a typical install is roughly 13.5% of the price. Whatever the grant does in 2027, the VAT position is unaffected — it is separate legislation with no scheduled end date under current law.

BER Scale Change From 24 May 2026: What It Means for 2027 Applications
From 24 May 2026, Ireland's BER rating scale changes from the A1–G15 format to a simplified A0–G scale, in line with EU energy performance requirements. The change is administrative — it does not affect grant eligibility or the grant amount. Any post-works BER completed from 24 May 2026 onward will show the new scale, including all 2027 installs.
The grant application process is otherwise unchanged for 2027: you apply before the install begins, SEAI emails you a Letter of Offer, the install goes ahead, a registered BER Assessor completes the post-works BER, and your solar PV company uploads the Declaration of Works. SEAI pays the grant to your bank account 4–6 weeks after that.
What Budget 2027 Means Practically
Budget 2027 (6 October 2026) announced no cut. What that means:
If you are at the quoting stage now: The rate of €1,800 is available. SEAI pays the grant amount in effect when you apply — not when the install completes. Once approved you have 8 months to finish the works, so an application made in October 2026 covers a spring 2027 install at today's rate. Check the validity window on your actual offer letter when you receive it, as SEAI has changed this period before.
If you are not yet at the quoting stage: Getting quotes costs nothing and commits you to nothing. Get two or three quotes from SEAI-registered installers now, confirm your home's eligibility, and make the call with real cost figures in hand.
If you plan to install in 2027: Check seai.ie on the day you apply. No cut has been announced, but the government's stated plan still allows one.
What Else Can You Stack With the 2027 Grant
The stacking rules for the solar grant are not expected to change in 2027. On current rules:
0% VAT — stacks. Applies to all residential solar installs regardless of year, as above.
Heat Pump Grant — stacks. The SEAI Heat Pump Grant (currently up to €10,500 for the unit, plus up to €2,000 central heating support and a €2,000 boiler scrappage grant, totalling up to €14,500 for a house) funds a different piece of equipment and can be claimed alongside the solar grant for the same property. Different eligibility rules apply — the heat pump grant is for homes built and occupied before 2021, and pre-2007 homes must show low enough heat loss (a BER Heat Loss Indicator of 2.3 or better, or a technical assessment). There is no B2 BER requirement. See the SEAI Heat Pump Grant page for current figures.
EV Home Charger Grant (€300) — stacks. The SEAI EV Home Charger Grant is separate from the solar grant and can be claimed on the same property. See the SEAI EV charger grant page.
Clean Export Guarantee (CEG) — not a grant, but relevant. Once your solar system is connected and your NC6 form is processed by ESB Networks, your electricity supplier pays you a rate per kWh for surplus electricity exported to the grid. The first €400/year of CEG income is tax-free for 2024 to 2028, and Budget 2027 raises that to €600 from 2027 (see Revenue.ie microgeneration relief). CEG rates vary by supplier — check current supplier rates before signing a contract. See our Clean Export Guarantee rates guide for the current comparison.
TAMS (farmers only) — does not stack. TAMS 3 funds solar PV on farm holdings but cannot be combined with the SEAI residential solar grant for the same installation. Choose one scheme.
One Stop Shop (deep retrofit) — different route. If you are doing a full deep retrofit through an SEAI One Stop Shop provider, solar PV may be included in the bundled grant package rather than claimed separately. Check with your One Stop Shop provider which route delivers better value for your specific combination of measures.
How to Check the Current Rate
Any change will appear on SEAI's Solar Electricity Grant page first. Citizens Information updates their solar panels page after that. Those are the two sources worth checking. Do not rely on installer websites or comparison sites for the confirmed figure — some are slow to update, and some publish projections as confirmed figures.
Updated 7 October 2026, after Budget 2027. We update this page within 7 days of any confirmed change.
Getting quotes now does not commit you to anything. It gives you the real installed cost figure so you can decide with numbers in hand. Every installer in the Solar Quotes Ireland network is SEAI-registered. There is no fee to homeowners.

Frequently Asked Questions: SEAI Solar Grant 2027
As of 7 October 2026 the grant is still €1,800, and Budget 2027 (6 October 2026) announced no cut. The government's published plan to reduce the grant by up to €300 per year would mean €1,500, but no 2027 cut has been announced, and the same planned reduction was dropped for 2026. Check seai.ie on the day you apply.
Yes — the SEAI solar grant is due to continue until 2029 on current government plans. The grant does not disappear in 2027. It would drop from €1,800 to around €1,500 if the €300/yr step-down goes ahead, but Budget 2027 announced no cut. The scheme's published end date is 2029, per Citizens Information (10 March 2026). A new government could extend or alter the scheme before that date.
For most homes, installing now is better value than waiting. If the 2027 grant drops by €300, the net saving from waiting is roughly €125 on a 4 kWp system once you account for the typical fall in panel prices over a year. That €125 is wiped out in about six weeks of electricity savings your panels would have generated while you waited. For the full numbers, see our install in 2026 or wait guide.
Yes. SEAI pays the grant amount in effect when you apply, not when the install completes. Once your application is approved you have 8 months to finish the works, so an install and post-works BER completed in early 2027 still attract the rate in force when you applied in 2026. If you cancel and reapply, the rate on the day of the new application applies. Verify the validity window on your actual offer letter when you receive it, as this detail is subject to policy review.
Eligibility has already changed once. From 6 October 2026 the building age rule for solar PV and solar thermal moved out from homes built and occupied before 2021 to before 2025, widening the scheme to four more years of housing stock. The other conditions — no minimum BER rating, SEAI-registered installer only, Republic of Ireland properties — were untouched, and nothing published so far points to a further eligibility change in 2027. Full detail in our write-up of October 2026's grant changes.
Budget 2027 (6 October 2026) announced no cut, so there is no confirmed 2027 rate change. If one comes, it will appear first on seai.ie, with Citizens Information following.
The solar PV grant itself covers panels and inverter only. But since 6 October 2026 SEAI offers a separate flat €600 battery grant for batteries of 5 kWh or more, and you can apply for both in a single application. Typical 2026 battery costs run from €1,500–€2,500 for a 5 kWh battery fitted with new panels to €4,000–€6,000 for a 10 kWh battery.
No change has been announced. The 0% VAT on the supply and installation of solar panels on private dwellings has been in place since 1 May 2023 and is not time-limited under current Revenue rules. It is separate legislation from the SEAI grant. See revenue.ie for the current position.
