SEAI Solar Grant 2026: Claim Up to €1,800 Off Your Solar PV Install

The SEAI Solar Electricity Grant pays up to €1,800 off the cost of installing solar PV on your home in Ireland in 2026. The grant is funded by the Sustainable Energy Authority of Ireland, applied for by you (naming an SEAI-registered company) before the install begins, and paid to your bank account after the work is completed and a post-works BER assessment is uploaded (SEAI Solar Electricity Grant; citizensinformation.ie). This is one of eight SEAI home energy grants available in 2026 — see the full list of SEAI grants for everything else you can claim.

If you are quoting for solar today, the €1,800 cap is the number that matters: it lands when your system is 4 kWp or larger, and it is the most the standard solar PV grant pays. Since 6 October 2026 a separate €600 SEAI grant covers a home battery of 5 kWh or more, so panels plus battery can now bring in up to €2,400.

How the Grant Value Is Calculated

The SEAI Solar Electricity Grant is paid in two tiers based on the kWp size of your installed system:

Tier	kWp band	Rate	Tier max
1	First 2 kWp	€700/kWp	€1,400
2	Next 2 kWp (2–4 kWp)	€200/kWp	€400
Total at 4 kWp			€1,800

Anything above 4 kWp attracts no further grant — the cap is hard-coded at €1,800.

Worked example — 4 kWp system installed May 2026

On a 4 kWp system installed in May 2026, the grant breaks down as:

• 2 kWp × €700 = €1,400
• 2 kWp × €200 = €400
• Total: €1,800

A 4 kWp system is usually 9–11 panels (modern panels are 400–450W each — for example, 10 × 410W Jinko panels gives a 4.1 kWp system, which still caps at €1,800). On a south-facing Irish roof, that system generates roughly 3,200–3,800 kWh per year, enough to cover 60–80% of a typical home's electricity use depending on consumption pattern.

Worked example — 3 kWp system

If you install a 3 kWp system (say a smaller terrace roof with limited unshaded area):

• 2 kWp × €700 = €1,400
• 1 kWp × €200 = €200
• Total: €1,600

The €200 saving you "forfeit" by sizing below 4 kWp is rarely worth chasing — the right system size is the one that fits your roof and matches your consumption, not the one that maximises the grant.

Eligibility — Who Can Get It

The SEAI solar grant is available to homeowners across all 26 counties. To qualify, your home must meet four conditions. For the full condition-by-condition breakdown, including landlords, the post-works BER and the cases people get wrong, see our guide to SEAI solar grant eligibility. And if anyone in the household receives Fuel Allowance, Carer's Allowance, Working Family Payment or one of four other welfare payments, the figure on this page is the wrong one to be reading — from 6 October 2026 those households get an enhanced grant of up to €9,000 rather than €1,800.

1. 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. Since 6 October 2026 the cut-off is homes built and occupied before 2025 (it used to be before 2021). A home built or first occupied in 2025 or later is not eligible; new builds usually meet Part L with a heat pump or solar instead.

2. A post-works BER is required.
You do not need a minimum BER rating. The B2 minimum that some older guides reference was removed in 2022. What is required is a post-works BER assessment after install, completed by a registered SEAI BER Assessor and published on the National BER Register before the grant is paid. A post-works BER costs roughly €150–€250 from a registered assessor.

3. Installed by an SEAI-registered installer.
This is the most common rejection cause. The company must be on the SEAI's registered list and named in your application on mgen.seai.ie. You (not the installer) are the applicant, but you cannot apply retrospectively or use a non-registered electrician. If a quote comes in from an electrician who is not SEAI-registered, the grant is gone — no exceptions.

4. Located in Ireland (all 26 counties).
Northern Ireland has a separate scheme. The SEAI grant only applies to homes in the Republic of Ireland.

Renters and landlords: the grant is paid to the bill-payer who commissions the work, typically the property owner. Renters cannot apply directly; landlords can apply for properties they own — and on top of the grant a landlord can claim a separate tax deduction for the works. See our guide to solar panels for landlords for the grant and tax reliefs on a rental.

Apartments: an individual apartment owner can't normally apply, because the block's roof is a common area owned by the management company — but owner management companies (OMCs) are eligible SEAI applicants and can apply for the block. See our guide to the SEAI solar grant for apartments.

Commercial properties: not eligible under this scheme. Businesses claim under the Accelerated Capital Allowance (100% year-1 write-off) and 23% VAT (not the 0% residential rate).

The Application Process — 7 Steps

The SEAI solar grant is applied for before your install begins. Your installer handles the portal submissions; your job is the home eligibility check, the BER, and the bank-detail confirmation.

Step 1: Confirm your home is eligible

Before you spend time getting quotes, do the 30-second eligibility check. Your home must have been built and occupied before 1 January 2025 (check your ESB bill for your MPRN; the connection date is in your records or available from ESB Networks on request). A BER must already exist for the property, or you must be prepared to commission one — though for the grant, the post-works BER after install is what's required.

Step 2: Get quotes from SEAI-registered installers

Get at least two or three quotes from installers on the SEAI's registered list. Quotes should be itemised: panels (brand, wattage, count), inverter, mounting, cabling, scaffolding, BER assessment, grid connection (NC6 submission), and the gross/net price showing the grant deduction. Get a quote from SEAI-registered installers here — every installer in the Solar Quotes Ireland network is SEAI-registered.

Step 3: You apply for the grant, naming your installer

Once you have picked your company, you apply on mgen.seai.ie as the homeowner (many installers will walk you through it). You need: your MPRN, your name and address, the year the house was built, the proposed system size in kWp, the SEAI-registered company you are using, and the bank details SEAI will pay the grant into.

Step 4: SEAI approves the grant offer

SEAI processes the application and issues a Letter of Offer, typically within 2–4 weeks of submission. The Letter of Offer confirms the grant amount for your system size, at the rate in force on the day you applied. Until you have the Letter of Offer, the install cannot begin — installing before approval forfeits the grant entirely. This is the second most common rejection cause after non-registered installers.

Step 5: Installation goes ahead

Your installer schedules the install (typically 1–3 days on-site for a residential system). The system is commissioned, the inverter is configured, Before that, the installer must have sent the NC6 connection form to ESB Networks: SEAI says this goes in before the system is installed and usually takes at least 4 weeks (20 working days). You receive the system handover pack including warranties, the commissioning certificate, and a wiring diagram.

Step 6: Post-works BER + Declaration of Works submitted

After install, a registered SEAI BER Assessor visits to complete the post-works BER assessment (mandatory). Your solar PV company then uploads the Declaration of Works pack to SEAI — the signed Declaration of Works, test and commissioning certificate, Safe Electric (RECI) certificate, completed NC6 form, install photos and the invoice. The BER assessor publishes the post-works BER on the National BER Register. This must be submitted within the grant offer's validity window (currently 8 months from offer date — confirm against the live offer letter, as windows have changed).

Step 7: SEAI pays the grant

SEAI reviews the Declaration of Works and, once approved, pays the grant directly to your bank account. SEAI aims to process payment promptly after acceptance — allow 4–8 weeks from Declaration of Works submission as a working estimate. The grant goes to the bank account entered on the application: SEAI allows either your own account or the solar PV company's. If it comes to you, your installer's invoice is the gross amount and the grant reimburses you separately.

The BER A0–G Scale Change (24 May 2026)

From 24 May 2026, Ireland's BER rating scale switches from the long-running A1–G15 letter+number format to a simplified A0–G scale, aligning Ireland with new EU energy performance rules.

What is changing: The scale becomes a 7-band A0–G format. A0 is the new top band (replacing parts of A1/A2), G is the lowest band (replacing the existing G15 floor).

What is not changing: Existing BER certs remain valid until their expiry date (BERs last 10 years). You don't need a new BER just because the scale changed.

Why it matters for the SEAI solar grant: It doesn't change eligibility — the grant has had no minimum BER rating requirement since 2022. What it does change is the form of the post-works BER cert your installer uploads after the install. From 24 May 2026, that cert will display on the A0–G scale. If a quote or installer document references the old A1–G15 format after that date, ask them to update.

For most homeowners, the answer is: the scale change is administrative and does not affect what you can claim.

How Busy Is the SEAI Grant Scheme Right Now?

SEAI processed more than 10,000 solar PV grant applications in Q1 2026 — a 65% increase year-on-year versus Q1 2025, when roughly 6,100 applications were processed. March 2026 alone saw more applications than any single month on record, according to a statement from Minister O'Brien in April 2026 (gov.ie press release, April 2026).

This is not a general warning about solar demand — it is a specific, dateable supply constraint. Demand is up 65% in one year; installer capacity has not scaled at the same rate. The queue is real.

The Planned €300/Year Step-Down — Urgency Hook

The government has publicly signalled that the SEAI solar grant will be reduced by up to €300 per year, as solar panel costs fall. The current Citizens Information page (dated 10 March 2026) states: "The Government plans to reduce the grant by up to €300 every year, as the cost of solar panels reduce" (citizensinformation.ie).

What that means in numbers:

Year	Likely max grant	Change vs. 2026
2026	€1,800	—
2027	€1,500 (possible, not announced)	−€300
2028	€1,200 (possible, not announced)	−€600

These figures show what the signalled €300/yr trajectory would mean. Budget 2027 (6 October 2026) announced no cut, and the 2026 cut never happened either. As of 7 October 2026 SEAI still lists €1,800.

The practical implication: if you are going to install solar this year anyway, doing it in 2026 rather than 2027 would preserve €300 if a cut does come. That is about three months of savings on a 4 kWp system saving around €1,100 a year. SEAI pays the rate in force when you apply, so an application made before any announced cut keeps the current rate.

This is not a scare tactic. The grant has stepped down before (it was €2,100 in 2024) and could step down again. Plan accordingly.

Common Reasons SEAI Grant Applications Get Rejected

The grant has a high approval rate when the basics are right. When applications are rejected, it's usually one of these six reasons:

1. The installer is not on the SEAI registered list. This is the single biggest cause. A standard Safe Electric / RECI registered electrician is not the same as an SEAI-registered solar installer — the SEAI runs a separate Renewable Installer list. Always check the installer is on the SEAI registered installer list before signing.
2. The system installed is larger than 4 kWp and the homeowner tried to claim grant on the full system size. The cap is at €1,800 regardless of system size. Some applications get rejected when paperwork is submitted as if a 6 kWp system attracts more grant — it doesn't.
3. Build date verification failed. If the home was built or first occupied in 2025 or later, it is not eligible (the cut-off was before 2021 until 6 October 2026). If you are unsure of the year, ESB Networks can tell you when the property was first connected. Check before applying, not after.
4. No post-works BER published. The post-works BER is mandatory before payment. Forgetting to commission it (or commissioning a pre-works BER instead) leaves the file incomplete and the grant unpaid. Book the post-works BER assessor as soon as the install date is confirmed.
5. Declaration of Works submitted outside the grant offer's validity window. Currently 8 months from the date of the Letter of Offer (verify against your live offer). If install is delayed past the window, the offer expires and you must reapply — but reapplication may land at a lower grant amount if the year has changed.
6. Double-claiming with TAMS where the property is ineligible. TAMS 3 (the Targeted Agricultural Modernisation Scheme for farmers) supports solar PV on farm holdings, but the SEAI solar grant and TAMS cannot both fund the same panels. Farmers must choose one scheme per installation.

Three more that come up less often: applying after install has begun (must be approved first), incomplete bank details (delays payment indefinitely), and inverter or panel models not on the SEAI's approved equipment list.

Can You Stack the SEAI Solar Grant With Other Schemes?

Stacking is allowed in some cases and not in others. The breakdown:

0% VAT on residential solar PV — stacks. Since May 2023, the supply and installation of solar PV on private dwellings is zero-rated for VAT in Ireland. The grant and the VAT relief stack: your installer's quote is already at 0% VAT, and the €1,800 grant comes off the top of that. Combined, the effective saving on a typical residential install is roughly €3,000 vs. the pre-2023 equivalent.

Heat Pump Grant — separate, no conflict. The SEAI Heat Pump System grant is now up to €14,500 for a house (unit grant plus central heating and boiler scrappage elements). It has different rules from the solar grant: the home must be built and occupied before 2021 and, if built before 2007, 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. It funds a different piece of equipment and can be claimed alongside the solar grant on the same property — they are two separate applications.

EV Home Charger Grant — separate, no conflict. The SEAI EV Home Charger Grant is €300 and applies to charger installation. Stackable on the same property as the solar grant.

Microgeneration Support Scheme / Clean Export Guarantee (CEG) — separate, no conflict. Once your solar is installed and the NC6 form is processed, your electricity supplier pays you a per-kWh rate for surplus electricity exported to the grid. This is an income stream, not a grant. The first €400/year of CEG income is tax-free for 2024 to 2028, and Budget 2027 raises that to €600 from 2027. CEG export rates vary by supplier from ~15.89c/kWh to a maximum of 32c/kWh (SSE Airtricity's premium tariff via Activ8). See our Clean Export Guarantee rates by supplier for the live comparison table.

TAMS (for farmers) — does not stack. TAMS 3 funds solar PV on farms, but a single installation cannot be funded by both TAMS and the SEAI solar grant. Choose one.

One Stop Shop (whole-home upgrade) — different route. If you are doing a full deep retrofit through an SEAI One Stop Shop, solar PV is included in the bundled grant package, not claimed separately.

How Long Does the Whole Process Take?

A realistic timeline from quote request to grant payment:

Stage	Typical duration
Get and compare 3 installer quotes	1–2 weeks
You apply on mgen.seai.ie, naming your chosen installer	Same week
SEAI issues Letter of Offer	2–4 weeks
Install scheduled and completed	2–6 weeks
Post-works BER assessment	1–2 weeks after install
Declaration of Works submitted	Same week as BER
SEAI reviews and pays grant	Allow 4–8 weeks after Declaration of Works
Total: quote request to grant payment	8–16 weeks

The longest variable is the install date itself — installers are busy through summer, and slots in June–August are typically booked 4–8 weeks in advance. Get quotes early if you want to install before autumn.
