SEAI grants are the financial backbone of Ireland’s solar market. Without them, payback periods for residential solar would stretch beyond what most homeowners accept. Understanding the grant structure — residential, commercial, agricultural, and community — is essential for any installer or solar company operating in Ireland. Solar design software that factors Irish grant amounts into financial projections makes proposals more credible and helps customers see accurate payback periods.
This guide covers every SEAI solar grant available in 2026: who qualifies, how much they pay, and the exact steps to apply and claim. See the Ireland solar compliance hub for the broader compliance picture including grid connection and planning rules.
Critical Compliance Point
Using a non-SEAI-registered installer voids grant eligibility completely. SEAI maintains a public register of approved Solar PV and Non-Domestic Microgen installers. Always verify registration before quoting or commencing work. SEAI may carry out physical inspections, and grant claims from unregistered installers are rejected outright.
SEAI Residential Solar PV Grant
The SEAI Solar Electricity Grant is the most widely used solar incentive in Ireland. It has supported the installation of solar panels on tens of thousands of homes since its introduction.
Grant Amounts (2026)
| System Size | Rate | Total Grant |
|---|---|---|
| 1 kWp | €700/kWp | €700 |
| 2 kWp | €700/kWp | €1,400 |
| 3 kWp | €700 (first 2 kWp) + €200 (next 1 kWp) | €1,600 |
| 4 kWp and above | €700 (first 2 kWp) + €200 (next 2 kWp) | €1,800 (maximum) |
The maximum grant of €1,800 has been frozen at this level for 2026. An earlier planned reduction was reversed in late 2025, maintaining the current rates.
Eligibility Requirements
| Requirement | Detail |
|---|---|
| Property age | Built and occupied before 1 January 2021 |
| Applicant | Homeowner or private landlord |
| MPRN | Valid Meter Point Reference Number required |
| Installer | Must be SEAI-registered Solar PV installer |
| Previous grants | No previous SEAI solar PV grant at same MPRN |
| DIY | Not permitted — voids eligibility |
| BER | Post-works BER assessment mandatory |
The 0% VAT rate on residential solar supply and installation remains in effect for 2026. This applies to panels, inverters, mounting systems, cabling, and labour.
Application and Claim Process
Apply online through the SEAI portal
The homeowner (not the installer) creates an account and submits the application. Approval is typically granted within minutes for straightforward applications. SEAI issues a Letter of Offer valid for 8 months.
Installer submits NC6 to ESB Networks
At least 20 working days before installation, the Safe Electric-registered installer submits the NC6 Microgeneration Notification Form to ESB Networks with the customer’s MPRN and system specifications.
Complete installation and obtain certifications
The SEAI-registered installer carries out the installation and provides: Safe Electric (RECI) completion certificate, Inspection Test and Commissioning Certificate, signed Declaration of Works, and photographs of the installed system.
Arrange post-works BER assessment
A registered SEAI BER Assessor visits the property, records the solar installation, and publishes the updated BER certificate on the National BER Register. Cost is typically €150–€300.
Submit grant claim and receive payment
The homeowner submits all documentation through the SEAI portal: BER certificate, itemised invoice, Safe Electric certificate, Declaration of Works, NC6 confirmation, and installation photographs. SEAI processes payment within 4–6 weeks.
Required Documentation Checklist
- Signed Declaration of Works from registered installer
- Safe Electric (RECI) completion certificate
- Inspection, Test and Commissioning Certificate
- Completed ESB Networks NC6 form
- Post-works BER assessment (published on National BER Register)
- Itemised invoice describing all works
- Photographs of the installation
SEAI carries out physical inspections on a sample basis. If issues are identified, the contractor must return to rectify them before grant payment is released.
SEAI Non-Domestic Microgen Grant (NDMG)
The NDMG is the primary grant for commercial, industrial, agricultural, and community solar installations in Ireland.
Grant Structure (2026)
| System Size | Grant Rate | Example Grant |
|---|---|---|
| 0–2 kWp | €900/kWp | €1,800 (at 2 kWp) |
| 2.1–4 kWp | €300 per additional kWp | €2,400 (at 4 kWp) |
| 4–6 kWp | Flat cap | €2,400 |
| 7–20 kWp | €300/kWp | €6,600 (at 20 kWp) |
| 21–200 kWp | €200/kWp | €40,000 (at 200 kWp) |
| 201–1,000 kWp | €150/kWp | €162,600 (maximum at 1,000 kWp) |
Who Qualifies
- Private businesses and sole traders
- Farms and agricultural enterprises
- Public sector bodies

Key Requirements
| Requirement | Detail |
|---|---|

The NDMG grant rates were not reduced in 2026. The maximum remains at €162,600, in contrast to the residential grant which was reduced in 2025.
Additional Financial Benefits for Businesses
| Benefit | Detail |
|---|---|
| Accelerated Capital Allowances | 100% write-off in Year 1 |
| Clean Export Guarantee (CEG) | Sell surplus at competitive rates (15–32c/kWh) |

TAMS 3: Solar Grants for Farmers
The Department of Agriculture, Food and the Marine administers TAMS 3, which includes a Solar Capital Investment Scheme (SCIS) specifically for agricultural properties.
TAMS 3 SCIS Details
| Feature | Detail |
|---|---|
| Grant rate | 60% of eligible costs |
| Young Farmer rate | Up to 80% of eligible costs |
| Investment ceiling | €90,000 per farm holding |
| Maximum grant (60%) | €54,000 |
| Maximum grant (80%) | €72,000 (Young Farmers) |
| Eligible system size | Up to approximately 62 kWp |
TAMS 3 vs NDMG for Farmers
Farmers cannot combine TAMS 3 and NDMG on the same system. The choice depends on system size:
| System Size | Better Option | Reason |
|---|---|---|
| Under 20 kWp | TAMS 3 | 60% flat rate usually exceeds NDMG tiered rate |
| 20–50 kWp | TAMS 3 | Still favourable due to high percentage |
| 50–200 kWp | Compare both | Depends on exact system size and cost |
| Over 200 kWp | NDMG | Higher maximum (€162,600 vs €54,000) |
Recent Changes (Late 2025/Early 2026)
TAMS Tranche 9 introduced new ranking and selection criteria in November 2025. According to industry reports, these changes have reduced approval rates for solar installations significantly. Farmers applying for TAMS 3 solar should:
- Apply as early as possible in the tranche window
- Ensure all documentation is complete and accurate
- Consider NDMG as a fallback if TAMS 3 approval is uncertain
Better Energy Communities
The Better Energy Communities scheme funds community-based energy projects including solar PV installations.
How It Works
- Applications are submitted through SEAI Project Coordinators
- Monthly submission cut-offs apply
- Funding is available for housing associations, community groups, local authorities, and mixed projects
- Projects must demonstrate energy savings and community benefit
Typical Projects
- Social housing solar installations
- Community centre rooftop solar
- School solar projects
- Local authority building portfolios
- Mixed residential-commercial developments
The scheme operates on a rolling basis, but funding is competitive. Projects with strong energy savings projections and clear community benefit statements have the best chance of approval.
SEAI Warmer Homes Scheme
While not a solar-specific grant, the Warmer Homes Scheme provides free energy upgrades to low-income households on qualifying welfare payments. Solar PV may be included as part of a broader upgrade package in some cases, though the primary measures are insulation and heating upgrades.
Eligibility is based on means-tested welfare payments, and the scheme is administered directly by SEAI-approved contractors rather than through the standard grant portal.
