What is the SEAI?

The SEAI (Sustainable Energy Authority of Ireland) is a government-funded organisation that supports Ireland’s transition to clean energy. It offers grants, advice, and research to help homeowners, businesses, and communities reduce their energy use and carbon emissions.

Through its Solar PV Grant scheme, the SEAI helps reduce the cost of installing solar panels on Irish homes — making it easier for households to cut bills and carbon at the same time.

How does SEAI support solar panel installations?

The SEAI Solar PV Grant provides financial assistance to homeowners installing solar photovoltaic (PV) panels and optional battery storage. The grant helps cover part of the installation cost and makes solar energy more accessible and affordable across Ireland.

How much is the SEAI Solar PV Grant worth?

The current SEAI grant amounts (as of 2025) are as follows:

System sizeGrant amount
First 2 kWp €900 per kWp
Additional capacity €300 per additional kWp (up to 4 kWp total)
Maximum grant €2,400

Example:
A 3 kWp system would qualify for:
€900 + €900 + €300 = €2,100
A 4 kWp system would qualify for:
€900 + €900 + €300 + €300 = €2,400

Who is eligible for the grant?

To qualify for the SEAI Solar PV Grant, you must:

  • Own a home built before 2021
  • Use the system mainly for your own electricity needs
  • Install the system through an SEAI-registered solar installer
  • Ensure your home has a BER of C or higher after installation

Important: You must apply for the grant before starting any installation work or purchasing materials.

How do I apply for the grant?

The application process is straightforward and completed online. Here’s how it works:

  1. Choose a SEAI-registered installer
  2. Submit your application via the SEAI website
  3. Wait for approval before starting any work
  4. Have your system installed
  5. Complete a post-works BER assessment
  6. Submit final documentation to SEAI for payment

Most SEAI-registered installers will help you through every step of this process.

What are the requirements for installation?

To qualify for the grant, your system must:

  • Be installed by a SEAI-registered contractor
  • Meet all building regulations and electrical safety standards
  • Be grid-connected (if applicable)
  • Include metering or monitoring equipment

If battery storage is included, additional funding may apply under past SEAI pilot schemes — check availability with your installer.

Can I combine the grant with other energy upgrades?

Yes — solar PV is often installed alongside other upgrades such as:

  • Home insulation (attic, wall, or floor)
  • Heat pump systems
  • Energy-efficient windows and doors

These improvements may be eligible for separate SEAI grants. Combining upgrades can help boost your BER rating and unlock greater financial support.
