Irish homeowners can receive up to €1,800 toward the cost of solar panels through the SEAI solar PV grant in 2026. On top of the grant, solar panel installation in Ireland also benefits from 0% VAT — making it one of the most cost-effective home energy upgrades available.
With electricity prices remaining high, solar panels typically pay for themselves within 6–10 years after the grant — and you can also earn money by selling surplus electricity back to the grid.

How Much Is the Solar Panel Grant in 2026?
The SEAI solar PV grant is calculated per kilowatt-peak (kWp) of panels installed:
| System size | Grant amount |
|---|---|
| Up to 1 kWp | €900 |
| 2 kWp (maximum supported) | €1,800 |
The grant is capped at 2 kWp (€900/kWp). A 2 kWp system is sufficient for most Irish homes to cover a significant portion of their daytime electricity use. Larger systems can be installed, but the grant only applies to the first 2 kWp.
0% VAT: Solar panel installations in Ireland also qualify for zero VAT — a saving of approximately €800–€1,200 on a typical installation.
Do I Qualify for the Solar Panel Grant?
To be eligible for the SEAI solar PV grant in 2026 your property must:
- Be in Ireland
- Have been built and occupied before 2021
- Not have previously received an SEAI solar PV grant
- Be a residential property (houses and apartments qualify)
The solar PV grant has a broader eligibility window than most SEAI grants — homes built as recently as 2020 can qualify, compared to 2011 for insulation grants.
What Does Solar Cost After the Grant?
A typical solar panel installation in Ireland in 2026:
| Cost item | Amount |
|---|---|
| Typical 2kWp system (installed, inc. battery) | €5,000–€8,000 |
| Less: SEAI solar grant | −€1,800 |
| Less: 0% VAT saving (vs 23%) | −€800 to −€1,200 |
| Typical net cost to homeowner | €2,000–€5,000 |
Earning Money from Solar — The Microgeneration Support Scheme
Any surplus electricity your panels generate can be sold back to the grid through Ireland’s Microgeneration Support Scheme. Export rates vary by supplier — typically 18–21 cent per kWh. There is also an income tax disregard of €400 per year for microgeneration income, extended to end of 2028.
The combination of bill savings and export income means most homeowners with solar see a genuine financial return within 7–10 years of installation.
How to Apply for the Solar Panel Grant
- Get quotes from at least two SEAI-registered solar PV installers
- Apply to SEAI at seai.ie before work starts — approval is required in advance
- Have the system installed by your registered contractor
- Ensure your installer registers your system with your network operator (required for grid connection)
- Submit your grant claim with invoice and completion documents
- Receive payment — typically 4–8 weeks
Can I Combine Solar Grants with Other SEAI Grants?
Yes. The solar PV grant can be combined with insulation grants, heat pump grants and heating controls grants. If you are going through the One Stop Shop route for a full deep retrofit, solar can be included as part of the package, with the One Stop Shop handling all grant applications on your behalf.

Frequently Asked Questions
How much is the solar panel grant in Ireland in 2026?
The SEAI solar PV grant in Ireland in 2026 is €900 per kWp, up to a maximum of €1,800 for a 2 kWp system. Solar installations also benefit from 0% VAT in Ireland, providing additional savings of approximately €800–€1,200 on a typical installation.
Can I get the solar grant if my home was built after 2011?
Yes. The solar PV grant is available for homes built and occupied before 2021 — a broader window than most other SEAI grants, which require the home to have been built before 2011. This means homes built up to 2020 can qualify for the solar grant even if they are not eligible for insulation or heating grants.
Do solar panels work in Ireland’s climate?
Yes. Solar panels generate electricity from daylight, not direct sunshine — so they work effectively in Ireland even on overcast days. Irish homes with solar panels typically generate enough electricity to cover 30–50% of their annual household electricity use, reducing bills significantly year-round.
Do I need planning permission to install solar panels in Ireland?
Generally no. Residential solar panel installations in Ireland are exempt from planning permission in most cases, provided the panels do not protrude more than 15cm from the roof surface and the home is not in a protected structure or an Architectural Conservation Area. Your installer can confirm your specific situation.
Can I get paid for selling solar electricity back to the grid?
Yes. Through Ireland’s Microgeneration Support Scheme, you can sell surplus electricity back to the grid at rates that vary by supplier, typically around 18–21 cent per kWh. There is also a €400 annual income tax disregard on microgeneration income, extended to end of 2028.
