Grants For Solar Panels in Ireland 2026 (With Calculator)

Energy prices have surged in recent years and for countless Irish homeowners, the idea of fitting solar panels feels beyond the budget. However, the idea might feel over expensive but the solar grant for residential installation has changed it all. The SEAI grant helps to cover the cost of installing solar panels on your home, giving you up to €1,800 towards the total price.
It’s a simple and affordable way to make renewable energy more affordable and half your electricity bills for good. In this guide, we’ll explain how the grant works, who can apply, and how Going Solar can help you every step of the way.

Solar Grant For Residential Installation

The solar grant for residential installation is part of Ireland’s renewable-energy push and is managed by the Sustainable Energy Authority of Ireland (SEAI). It offers homeowners financial help to install solar PV panels and start producing their own electricity at home. If your home was built and occupied before 2021, then you can safely apply for the grant.

The exact grant you receive depends on the size of your system, measured in kilowatt-peak (kWp). Larger systems qualify for a higher payment, up to the maximum amount set by the SEAI.

Example Grant Amounts 2026

System Size 2026 Grant Value Solar Panel Array
2.5 kWp
e.g. small 2 bed home
€1,500 ~12m2
6-8 panels
3.0 kWp
e.g. larger 2 bed home
€1,600 ~14m2
7-10 panels
3.5 kWp
e.g. standard 3 bed home
€1,700 ~17m2
8-12 panels
4 kWp
e.g. larger 3 bed home
€1,800 ~19m2
9-13 panels

€1,800 is the maximum grant.
Larger installations get this maximum amount.

Also, if you are adding anything extra such as battery storage systems or immersion diverters, this won’t affect your grant value. These can be added to your setup if you wish, but they aren’t included in the SEAI grant amount.

The grant is paid as a one-time payment directly to the homeowner once all the installation work has been completed, inspected, and approved by the SEAI.

How Much is the Grant Worth?

The amount of grant support you receive depends on the size of your solar system. This is measured by the peak generation capacity of your solar panels, which is usually in kW or kWp.

What Cost Can Be Covered Under the Solar PV Grant?

The solar grant for residential installation helps pay for both the equipment and the labour needed to fit a solar PV system. It covers the panels, inverter, mounting gear and all installation work carried out by your installer. In short, the grant goes directly towards the full cost of getting your solar panels up and running at home.

What About Batteries or Immersion Diverters?

The grant amount is based purely on the installation of solar panels, and does not include extra funding for batteries, immersion diverters, or other add-ons. These items can still be installed if you wish, but they won’t affect your SEAI grant value. There was previously a separate grant for solar battery storage, though that scheme was discontinued by the SEAI a few years ago.

Am I Eligible For a Grant?

Usually many homeowners in Ireland can qualify for the Solar Grant For Residential Installation. In fact, around 97% of domestic installations carried out by Going Solar receive approval from the SEAI. To check if your home meets the rules, look through the points below:

SEAI Solar Electricity Grant

The SEAI solar electricity grant helps homeowners and private landlords cut the cost of installing solar panels. It’s available for houses that were built and lived in before 31 December 2020 based on when the electricity meter was first connected. The grant can go up to €1,800 in 2026 which applies to systems of 4 kWp or larger. It’s a simple way for households across Ireland to make solar energy that is relatively more affordable.

How Can I Find the Most Appropriate System Size for My Home?

The solar system size depends on how much electricity your house uses and how much roof space you have. A good installer will check your recent energy bills, roof direction and how much sun your home gets through the year. Most Irish homes have 2 kWp and 4 kWp but the exact size can vary from one house to another. The easiest way to know for sure is to get an SEAI-approved installer to take a look and work out what will give you the best return for your home.
Can I Get a Solar PV System Larger Than 4 kWp?
You can, of course. Some homes want that bit more power. Just remember that the SEAI grant only covers the first 4 kWp. Anything bigger than that won’t get extra funding, though you can still install it if you like the idea of a larger setup.
Does the Grant Only Cover Roof-Mounted Solar PV Panels?
No, it isn’t limited to the roof. If your roof doesn’t suit, you can go for a ground-mounted system instead, as long as it meets the SEAI rules for the grant. Many rural homes choose this option when they have plenty of space outside.

Do I Need Planning Permission to Install Solar Panels to Get Grant Approval?

No. SEAI grant approval is not tied to planning permission. Most people can add panels without it, provided the installation follows normal guidelines.

What are the Planning Permission Rules for Home Solar Panels?

For most homes, you don’t need planning permission to put solar panels on the roof anymore. The rules changed in 2022, and the old limits were dropped. You can now cover your full roof if you want and the old 12 m² or 50% roof cap no longer applies anywhere in Ireland.
There are still a few rare cases to watch for. Homes that sit inside solar safeguarding zones might need permission under certain conditions. It’s best to have a quick chat with your installer or check with your local council before going ahead.

FAQ

Commonly Asked Questions

How long does it take to get the SEAI solar grant?

Can I apply for the grant before choosing an installer?
No. You’ll need to pick a registered SEAI installer first because their details go on your application. They’ll also help with the paperwork to make sure everything meets SEAI’s requirements.
Do I need to pay the installer before I get the grant?
Yes. You’ll pay your installer for the full job and then the grant amount is reimbursed directly to you by SEAI once everything is approved. It’s a simple refund process, not a discount at the start.
What happens if my home was built after 2020?
Homes built and first occupied after 31 December 2020 don’t qualify for the current SEAI solar grant. However, there may be other renewable energy supports available and your installer can advise you on the options.
Can I add a battery later if I don’t include one now?
