How much is the SEAI solar panel grant?
The SEAI Solar Electricity Grant helps homeowners install solar PV panels. The grant was confirmed at €1,800 maximum for 2026, reversing a planned €300 reduction.
| System Size | Grant Rate | Total Grant | Typical Net Cost |
|---|---|---|---|
| 1 kWp | €700/kWp | €700 | €1,500 – €2,500 |
| 2 kWp | €700/kWp | €1,400 | €2,000 – €3,000 |
| 3 kWp | €700 x 2 + €200 x 1 | €1,600 | €2,500 – €4,000 |
| 4 kWp+ | €700 x 2 + €200 x 2 | €1,800 (max) | €6,500–€7,200 |
Net costs include 0% VAT. Actual costs vary by installer, roof type, and system specification.
Eligibility
To qualify for the SEAI solar panel grant, your home must have been built and occupied before 2025 (before 2021 for applications made prior to 6 October 2026), you must be the property owner, and you must use an SEAI-registered installer. There is no means testing because the grant is property-based, not income-based. One grant is available per MPRN (electricity meter).
You qualify if:
- ✓ Your home was built and occupied before 2025
- ✓ You are the property owner (owner-occupier or landlord)
- ✓ Your home has an MPRN (electricity meter number)
- ✓ No previous solar PV grant claimed at this MPRN
- ✓ You use an SEAI-registered solar PV company
You don't qualify if:
- ✗ Your home was built in 2025 or later
- ✗ You are a tenant (only property owners can apply)
- ✗ A solar PV grant was already claimed at this address
- ✗ Work has started before receiving the Letter of Offer
No means testing. The grant is property-based, not income-based. It does not matter how much you earn.
Can I get the solar grant for a home built between 2021 and 2024?
Yes, from 6 October 2026. Until then the SEAI solar PV grant was limited to homes built and occupied before 2021, which shut out every home finished in 2021, 2022, 2023 or 2024. The cut-off is now before 2025, so those homes can apply for the first time.
- What a 2021–2024 home can now claim: the solar PV grant (up to €1,800), the new €600 battery grant and the solar thermal grant.
- What it still cannot claim: the heat pump grant, boiler scrappage, insulation and the other home energy grants, which keep the before-2021 rule.
- Homes built in 2025 or later: not eligible for any of these grants.
- Already have panels from the builder? The solar PV grant is for a new installation, with a grant offer in place before work starts. It cannot be claimed for panels that are already on the roof. The battery grant can be claimed on its own for a battery added to existing panels.
SEAI announced the change on 29 September 2026. Its own solar PV grant page still showed the before-2021 rule when we checked on 4 October 2026, so confirm the wording on SEAI's solar PV grant page before you apply.
What Does the Solar Panels Grant Actually Cover?
The €1,800 grant for solar panels in Ireland covers roughly 20–30% of the total installed cost of a typical home solar PV system, depending on system size. Smaller systems get a higher percentage of the cost covered (the grant is generous on the first 2 kWp); the largest systems hit the €1,800 ceiling.
| System | Solar Panel Cost (gross) | SEAI Grant | % of Cost Covered | Net Cost After Grant |
|---|---|---|---|---|
| 6 panels (2.6 kWp) | €6,500–€7,300 | €1,520 | 22% | €4,980–€5,780 |
| 8 panels (3.5 kWp) | €7,500–€8,500 | €1,700 | 21% | €5,800–€6,800 |
| 10 panels (4.4 kWp) | €8,300–€9,000 | €1,800 | 21% | €6,500–€7,200 |
| 12 panels (5.3 kWp) | €9,200–€9,900 | €1,800 | 19% | €7,400–€8,100 |
| 14 panels (6.2 kWp) | €10,500–€11,500 | €1,800 | 16% | €8,700–€9,700 |
| 16 panels (7 kWp) | €11,800–€13,000 | €1,800 | 15% | €10,000–€11,200 |
| 20 panels (8.8 kWp) | €14,000–€15,500 | €1,800 | 12% | €12,200–€13,700 |
On top of the cash grant, the 0% VAT rate on residential solar (since May 2023) effectively saves you another 13.5% versus the pre-2023 price. So between the grant and the VAT cut, the real cost of solar panels in Ireland today is roughly 30–40% lower than it was three years ago.
Quick worked example
For a 10-panel (4.4 kWp) home system at €8,300–€9,000 gross:
- SEAI grant: − €1,800
- Net cost paid by homeowner: €6,500–€7,200
- Annual electricity savings: €1,200–€1,800
- Payback period: 6–9 years
- 25-year return: 2–3× the initial outlay

Important conditions
- ✗ Buying panels separately without installation: 13.5% VAT applies
- ✗ Separate installation contract: reduced rate may apply
- ✓ Must be a single supply-and-install contract
- ✓ Expected to remain in place until at least 2027
Business grant for solar panels: the NDMG commercial solar grant
The SEAI Non-Domestic Microgen Grant (NDMG) is the main business grant for solar panels in Ireland, providing up to €162,600 for commercial solar PV installations. It supports businesses, farms, schools, community centres, and public bodies installing systems up to 1,000 kWp. The grant rate starts at €900/kWp for the first 2 kWp and decreases for larger systems. You must use an SEAI-registered Non-Domestic Microgen installer.
Temporary increase to 45% from 6 October 2026
For a period of 9 months, NDMG grant rates rise from about 23% of the cost of installation to 45% of eligible costs. SEAI estimates savings of around €12,000 a year for an average installation. Heat pumps and solar thermal under the Business Energy Upgrades Scheme also move to 45% of eligible costs. For applications from 7 October 2026 to 6 July 2027 the per-kWp rates are doubled and the maximum rises to €325,200, with SEAI paying the lower of that figure or 45% of the invoiced cost. The table below shows the standard rates; double them for the enhanced rate. See our commercial solar grants guide.
| System Size | Grant Rate | Example Grant |

How do solar feed-in tariffs work in Ireland?
Under Ireland's Microgeneration Support Scheme (Clean Export Guarantee), you can sell surplus electricity back to the grid. The first €400/year of export income is tax-free, rising to €600 from 2027 under Budget 2027.
| Supplier | Export Rate |
|---|---|
| SSE Airtricity (Premium via Activ8) | 32c/kWh Year 1, 27c Year 2 |
| Electric Ireland | 19.5c/kWh |
| SSE Airtricity (Standard) | 19.5c/kWh |
| Bord Gais Energy | 18.5c/kWh |
| Energia | 18.5c/kWh |
| Flogas | 18.5c/kWh |
| Pinergy | 18.5c/kWh (cut from 25c on 1 Aug 2026) |
Rates are set by individual suppliers and can change. Always verify directly with your supplier. Self-consumption (avoiding grid imports at 30–40c/kWh) is more valuable than exporting.
Requirements for Export Payments
- ✓ Smart meter installed (ESB Networks installs for free)
- ✓ NC6 application to ESB Networks for grid connection (your installer handles this)
- ✓ Microgeneration registration with your electricity supplier
- ✓ System up to 50 kWp for residential, 6 MWp for non-residential
Can businesses claim capital allowances on solar panels?
Businesses can claim 100% tax relief in Year 1 on solar PV investments through Accelerated Capital Allowances (ACA), instead of the standard 12.5% per year over 8 years.
Who qualifies
- ✓ Companies (corporation tax)
- ✓ Sole traders (income tax)
- ✓ Farmers (income tax on trading income)
Requirements
- ✓ Equipment must be new (not second-hand)
- ✓ Must be owned (not leased)
- ✓ Listed on SEAI Triple E Register at time of purchase
- ✓ Minimum qualifying cost of €1,000
Example: A €50,000 solar PV system at the 12.5% corporation tax rate yields a €6,250 tax saving in Year 1 (vs. €781/year under standard allowances).
Who qualifies for free solar panels in Ireland?
People who depend on electrically powered medical equipment at home can receive a fully funded solar PV system at no cost. From 6 October 2026 the Solar PV for the Medically Vulnerable Scheme covers up to 4 kWp of solar with 5 kWh of battery storage.
Eligibility
- ✓ Dependent on electrically powered medical equipment (dialysis, respirators, ventilators, oxygen therapy, nebulisers)
- ✓ Registered on the Priority Services Register with your electricity supplier
- ✓ Contact your supplier: Electric Ireland, Energia, SSE Airtricity, or Bord Gais Energy
Warmer Homes Scheme and welfare recipients
From 6 October 2026, solar PV (up to 4 kWp) and a 5 kWh battery are offered as standard under fully funded Warmer Homes Scheme upgrades. Separately, homeowners receiving one of the payments below can get a grant of up to €9,000 toward solar PV (up to 4 kWp) and a 5 kWh battery. You apply through SEAI's individual grants route and choose your own SEAI-registered contractor.
- Fuel Allowance as part of the National Fuel Scheme
- Jobseeker's Allowance for over six months, with a child under seven
- Working Family Payment
- One-Parent Family Payment
- Domiciliary Care Allowance
- Carer's Allowance, living with the person you care for
- Disability Allowance for over six months, with a child under seven
Can you get solar panels for free in Ireland?
Most homeowners cannot get solar panels completely free, but the combination of the SEAI grant (€1,800), 0% VAT (saving ~€1,000), and feed-in tariff income (15–32c/kWh) reduces the effective cost significantly. Payback is typically 4–6 years, after which the electricity is essentially free for 20+ years. Two groups can receive fully funded solar panels: medically vulnerable customers who depend on electrically powered equipment at home, and households receiving a fully funded Warmer Homes Scheme upgrade. From 6 October 2026 both cover up to 4 kWp of solar with a 5 kWh battery. Homeowners on certain social welfare payments can also get a grant of up to €9,000 toward the same system. See free solar panels in Ireland.
What's new for SEAI grants in 2026?
Enhanced Grants From 6 October 2026
A new €600 home battery grant, a €2,000 boiler scrappage grant, solar PV eligibility extended to homes built before 2025, solar and battery added to the Warmer Homes Scheme, and a temporary 45% grant rate for business solar. See the full list of changes.
Grant Stays at €1,800
Minister Darragh O'Brien reversed the planned €300 reduction. The residential grant remains at €1,800 for 2026. It is not yet confirmed whether reductions will resume in 2027.
National Solar Target
The Climate Action Plan 2024 targets 8 GW of solar capacity by 2030, with up to 5 GW by 2025. The residential grant is one of the main supports for the rooftop share of that target.
Tax-Free Threshold Raised
Budget 2027 raises the tax-free threshold for microgeneration export income from €400 to €600 a year from 2027. Budget 2026 had already extended the exemption to the end of 2028.
Record SEAI Budget
€654.5 million allocated for SEAI residential and community energy upgrade schemes in Budget 2027, up from about €640 million the year before.
160,000+ Solar Rooftops
Over 160,000+ Irish homes now have solar panels installed, with 33,000+ grants awarded in 2025, up from 28,000 in 2024.
Heat Pump Grant Doubles
From 3 February 2026, the total heat pump grant package increased from €6,500 to up to €12,500. The new breakdown: €6,500 for the heat pump unit, €2,000 for a central heating system upgrade (radiators or underfloor heating), and €4,000 renewable heat bonus for replacing a fossil fuel heating system. See our heat pump cost Ireland guide for what you'd actually pay after the grant.
Insulation Grants Increased
SEAI insulation grants increased from 3 February 2026. Cavity wall insulation grants now up to €1,800 and attic insulation up to €2,000. External wall insulation grants remain at up to €8,000. These increases make whole-home energy upgrades significantly more affordable.
Frequently Asked Questions About SEAI Solar Grants
How much is the SEAI solar panel grant in 2026?
The maximum residential grant is €1,800 for a 4 kWp+ system. The rate is €700 per kWp for the first 2 kWp, then €200 per additional kWp up to 4 kWp. The grant was confirmed at €1,800 for 2026 after a planned reduction was reversed.
Can I get the grant if my house was built after 2020?
Yes, if it was built and occupied before 2025. From 6 October 2026 the SEAI solar PV grant is available for homes built and occupied before 2025; previously the cut-off was before 2021. Homes built in 2025 or later are not eligible. Other SEAI grants, including the heat pump grant, still require a home built before 2021.
What size solar system should I get to maximise the SEAI grant?
The SEAI grant caps at €1,800 for 4 kWp or larger systems. A 4 kWp system (10 panels) is the most popular choice because it maximises the grant while keeping costs manageable. Going larger (6–8 kWp) costs more but generates more electricity and export income — the extra capacity just isn't grant-aided beyond 4 kWp.
Can I combine the solar grant with other SEAI home energy grants?
Yes. The solar PV grant can be combined with insulation, heat pump, heating controls, and other SEAI grants in the same application. See our <a href="/seai-home-energy-grants" class="link">full SEAI home energy grants guide</a> for all available grants and how to apply for multiple measures at once.
Can I get a grant for battery storage?
Yes. A new €600 SEAI grant for home battery energy storage systems opened on 6 October 2026. It is a flat €600 for batteries of 5 kWh or larger, in homes built and occupied before 2025, and it can be claimed together with the €1,800 solar PV grant or on its own. Batteries are also covered by 0% VAT when installed as part of the same solar contract.
How long does the grant application take?
The online application is often approved within minutes. Installation typically takes 1–2 days. The full process from application to grant payment takes 4–8 weeks, including the BER assessment and SEAI verification.
How do I find an SEAI-registered solar installer?
Use the <a href="https://www.seai.ie/grants/home-energy-grants/find-a-registered-professional/" target="_blank" rel="noopener noreferrer" class="link">SEAI register</a> to check your installer is approved, or browse our <a href="/installers" class="link">solar installer directory</a> — all listed installers are verified SEAI-registered. See our <a href="/seai-registered-contractors" class="link">SEAI registered contractors guide</a> for more. Get at least 2–3 quotes to compare prices and equipment.
Is there a government grant for solar panels in Ireland?
Yes. The Irish government provides a grant for solar panels through the Sustainable Energy Authority of Ireland (SEAI). Homeowners can receive up to €1,800, while businesses, farms, and community organisations can get up to €162,600 through the NDMG, with the rate temporarily raised to 45% of eligible costs for 9 months from 6 October 2026. A separate €600 grant for home battery storage also opened on 6 October 2026, and batteries qualify for 0% VAT.
How much is the grant for solar panels?
The solar panels grant in Ireland depends on your system size. Residential: €700 per kWp for the first 2 kWp, then €200 per kWp up to 4 kWp — maximum €1,800. For example, a typical 4.4 kWp system (10 panels) gets the full €1,800 grant. Commercial: starts at €900/kWp, with a maximum of €162,600. Combined with 0% VAT, a typical home system costs €6,500–€7,200 net after the grant.
Can farmers get a TAMS grant for solar panels?
Yes. Farmers can apply for solar panels through the TAMS (Targeted Agricultural Modernisation Scheme) administered by the Department of Agriculture. TAMS provides 40% grant aid (60% for young trained farmers) for solar PV on agricultural buildings. Farmers may also be eligible for the SEAI NDMG grant for commercial solar — but you cannot claim both TAMS and NDMG for the same installation. TAMS is suited for farm buildings, while NDMG suits any non-domestic property. See our guide to solar panels for farm buildings for the full TAMS route.
Is the grant available in Northern Ireland?
No. SEAI is a Republic of Ireland body. The grant is available in all 26 counties of the Republic. Northern Ireland has separate schemes administered by the NI government.
How much do solar panels cost in Ireland after the SEAI grant?
After the €1,800 SEAI grant and 0% VAT, a typical 4.4 kWp system (10 panels) costs approximately €6,500–€7,200 net. Prices range from €4,980 for a small 2.6 kWp system to €13,700 for a large 8.8 kWp system. Adding a 5 kWh battery adds €3,000–€4,500. See our <a href="/solar-panels-cost" class="link">full solar panel cost guide</a> for a detailed breakdown.
Who is eligible for the SEAI grant?
To be eligible for the SEAI grant, your home must have been built and occupied before 2025 for the solar PV grant (before 2021 for most other SEAI grants), you must be the property owner (owner-occupier or landlord), and the work must be carried out by an <a href="/seai-registered-contractors" class="link">SEAI-registered contractor</a>. There is no means testing — the grant is property-based, not income-based. One solar grant is available per MPRN (electricity meter). Rental properties are eligible if the landlord applies.
What does SEAI stand for?
SEAI stands for the Sustainable Energy Authority of Ireland. It is the government body responsible for promoting sustainable energy in Ireland, administering grants for solar panels, heat pumps, insulation, and other energy upgrades, and maintaining the register of approved contractors.
How do SEAI grants work?
SEAI grants work as a cashback payment. You apply online at seai.ie, receive a Letter of Offer, then have the work done by an <a href="/seai-registered-contractors" class="link">SEAI-registered contractor</a>. After installation and a BER assessment, SEAI pays the grant directly to your bank account within 4–6 weeks. Through a <a href="/one-stop-shops" class="link">one-stop-shop</a>, the grant is deducted upfront from your invoice.
