The SEAI Solar Electricity Grant is €1,800 in 2026 and is expected to fall to €1,500 in 2027, based on the government's published plan to reduce it by up to €300 per year until the scheme ends in 2029. The 2027 figure will be confirmed in the October 2026 budget — check seai.ie once announced. 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 the October 2026 budget decision 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, the cut came through Tier 2 (the 2–4 kWp band), not Tier 1. The same pattern is the most likely template for 2027, though there is no guarantee.
| Year | Max grant | Tier 1 (first 2 kWp) | Tier 2 (next 2 kWp) | Cap system size |
|---|---|---|---|---|
| 2024 | €2,100 | €900/kWp | €150/kWp | 4 kWp |
| 2025 | €1,800 | €700/kWp | €200/kWp | 4 kWp |
| 2026 | €1,800 | €700/kWp | €200/kWp | 4 kWp |
| 2027 (expected) | €1,500 (expected) | 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 are subject to budget confirmation in October 2026.
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 eligibility conditions for the SEAI solar grant have not changed for two years. Unless the October 2026 budget brings a policy amendment, these apply in 2027 as they do today:
Built and occupied before 1 January 2021. SEAI verifies this through your MPRN (Meter Point Reference Number) connection date held by ESB Networks. New builds from 2021 onward are excluded — they meet solar requirements through Part L of the Building Regulations instead.
No minimum BER rating required. The B2 minimum was removed in 2022. You need a BER on file for the property, and a post-works BER assessment must be completed after install and submitted before SEAI pays the grant. No minimum rating is required on either cert.
SEAI-registered installer only. The grant application goes in via mgen.seai.ie, submitted by your installer. A standard RECI or Safe Electric certified electrician who is not on the SEAI registered solar list cannot submit it. 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.
That makes the base case for 2027 straightforward: the €300 reduction deferred from 2026 is the most likely candidate for implementation in 2027. It still requires a budget decision and is not guaranteed — the 2026 exception shows it can be reversed — but it is the documented government intention.
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 | €7,000–€8,500 | €1,600 | €5,400–€6,900 | €1,300 (expected) | €5,700–€7,200 | +€300 |
| 4 kWp | €8,500–€10,500 | €1,800 | €6,700–€8,700 | €1,500 (expected) | €7,000–€9,000 | +€300 |
| 5 kWp | €10,000–€13,000 | €1,800 | €8,200–€11,200 | €1,500 (expected) | €8,500–€11,500 | +€300 |
| 6 kWp+ | €12,000–€16,000 | €1,800 | €10,200–€14,200 | €1,500 (expected) | €10,500–€14,500 | +€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.
Put alongside the €1,800 grant, the combined saving on a 4 kWp system is roughly €3,500–€4,000 compared to the same install at full VAT in 2022. 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: your installer submits before the install begins, SEAI issues a Letter of Offer, the install goes ahead, a registered BER Assessor completes the post-works BER, and your installer submits the Declaration of Works. SEAI pays the grant to your bank account 4–6 weeks after that.
What the October 2026 Budget Means Practically
The 2027 rate will be announced in the October 2026 budget. Until then:
If you are at the quoting stage now (May–September 2026): The 2026 rate of €1,800 is available. The rate is locked when SEAI issues the Letter of Offer — not when the install completes. A Letter of Offer issued in July 2026 is valid for 8 months, covering a Q1 2027 install at the 2026 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 after the October budget with real cost figures in hand.
If you plan to install in 2027: Do not plan around a specific grant figure until it is confirmed. The grant may be €1,500, or the hold may happen again. Wait for the October 2026 budget.
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 €6,500 base, plus €2,000 heating upgrade support and up to €4,000 renewable heat bonus for qualifying homes, totalling up to €12,500) 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 requires a post-works BER of B2 or above, which the solar grant does not. 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 under Revenue rules (extended to end of 2028 — 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 Get the Confirmed 2027 Rate When It Is Published
The October 2026 budget is the announcement date. Within days of the budget, SEAI updates the Solar Electricity Grant page with the confirmed rate and any revised tier structure. Citizens Information updates their solar panels page within a few days. 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.
This page will be updated within 7 days of the October 2026 budget with the confirmed 2027 rate, tier structure, and any eligibility changes.
Getting quotes now does not commit you to installing at the 2026 rate. It gives you the real installed cost figure so you can make an informed decision at the budget. Every installer in the Solar Quotes Ireland network is SEAI-registered. There is no fee to homeowners.

Frequently Asked Questions: SEAI Solar Grant 2027
The 2027 SEAI solar grant has not been officially confirmed as of May 2026. Based on the government's published plan to reduce the grant by up to €300 per year, the most likely 2027 rate is €1,500, down from the current €1,800. The exact figure will be confirmed in the October 2026 budget. The same planned reduction was reversed for 2026, so it is not guaranteed. Check seai.ie after October 2026 for the confirmed rate.
Yes — the SEAI solar grant is due to continue until 2029 on current government plans. The grant does not disappear in 2027; it is expected to reduce from €1,800 to around €1,500 if the €300/yr step-down proceeds as planned. 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, provided your SEAI Letter of Offer is issued at the 2026 rate. The grant rate is locked when the Letter of Offer is issued, not when the install completes. A Letter of Offer issued in 2026 is valid for 8 months from issue, meaning an install and post-works BER assessment completed in early 2027 would still attract the 2026 grant amount. Verify the validity window on your actual offer letter when you receive it, as this detail is subject to policy review.
No changes to eligibility rules have been announced as of May 2026. The existing conditions — home built before 1 January 2021, no minimum BER rating, SEAI-registered installer only, Republic of Ireland properties — are expected to remain unchanged in 2027. The October 2026 budget could alter these conditions, but no policy consultation on eligibility changes has been flagged publicly.
The 2027 rate will be confirmed in the October 2026 budget. SEAI updates its grant page within days of the budget announcement. Citizens Information typically follows within a week. If you want to receive the confirmation as soon as it is published, monitor seai.ie directly after the budget date.
No. The SEAI Solar Electricity Grant covers solar PV panels and inverter only — not battery storage. This is unchanged for 2027. A battery added to your install is paid out of pocket; typical 2026 costs are €2,000–€6,000 for a 5–10 kWh home battery. There is no standalone battery grant currently available in Ireland.
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.
