A new €600 grant for home battery storage is now available in Ireland as part of the Government’s latest package of home-energy supports.
The new SEAI Battery Energy Storage System Grant provides a flat-rate €600 grant towards qualifying home batteries with a capacity of 5kWh or larger.
It is available alongside the existing SEAI Solar PV Grant of up to €1,800, potentially making battery storage more affordable for Irish households considering solar panels.
And importantly, the battery grant isn’t only available to people installing solar panels for the first time. Existing solar homeowners can also apply, subject to the eligibility requirements.
Here’s what you need to know.
Is There a Battery Grant in Ireland?
Yes. SEAI has introduced a dedicated €600 Battery Energy Storage System Grant for eligible homeowners installing home battery storage.
The grant is available for batteries with a capacity of 5kWh or larger. Batteries below 5kWh aren’t eligible.
The new support forms part of a wider package of home-energy measures announced by Government around Budget 2027.
How Much Is the Battery Grant in Ireland?
The battery grant is a flat rate of €600.
Unlike the Solar PV Grant, the amount doesn’t increase depending on the size of the qualifying battery. A battery of 5kWh or larger can qualify for the €600 grant, subject to the other scheme requirements.
The existing SEAI Solar PV Grant provides up to €1,800 towards an eligible solar PV installation.
If you’re installing both Solar PV and qualifying battery storage, you can apply for both grants through a single application.
That means an eligible homeowner could potentially access up to €2,400 in combined standard grant support: up to €1,800 for Solar PV and €600 for battery storage.
Why Has a Solar Battery Grant Been Introduced?
Battery storage is becoming an increasingly important part of home solar systems.
A solar battery allows you to store surplus electricity generated by your solar panels during the day and use it later when your panels are producing less electricity.
According to figures reported by The Irish Times, around half of current solar installations now include battery storage. The Department of Energy has also estimated that a household with battery storage alongside a 4kWp solar PV system could potentially achieve annual savings of up to €900.
Actual household savings will vary depending on electricity consumption, tariffs, solar generation and how the system is used.
Can I Get the €600 Battery Grant If I Already Have Solar Panels?
Yes, subject to the eligibility requirements.
This is one of the most significant aspects of the new scheme for homeowners who installed solar panels without battery storage.
If you already have Solar PV, you can apply separately for the new €600 battery grant.
If you currently have a Solar PV grant application in progress, SEAI says you don’t need to amend that application. You can submit a separate application for the battery grant.
However, the battery installation must not begin before you have applied and received your Grant Offer from SEAI.
Can I Add a Battery to My Existing Solar Panels?
Yes, in many cases a battery can be added to an existing solar PV system.
However, the existing installation needs to be assessed first. Factors such as your inverter, current solar system, electrical setup, household electricity consumption and the type and capacity of battery all need to be considered.
An experienced solar installer can assess the existing system and recommend an appropriate battery configuration.
Who Can Apply for the €600 Battery Grant?
The grant is available for eligible properties owned by homeowners, including private landlords, Owner Management Companies and Approved Housing Bodies.
The home must have an MPRN and must have been built and occupied before 2025.
The battery must have a capacity of at least 5kWh and be installed by an SEAI-registered Solar PV Contractor.
A property isn’t eligible if it has previously received grant funding for a battery at the same MPRN.
If the property has Solar PV, a post-works BER is also required for the battery grant.

Can I add a battery to my existing solar panels?
Yes, in many cases. Your existing inverter, solar PV system and electrical setup should be assessed to determine compatibility and the most appropriate battery configuration.
Thinking About Solar Battery Storage?
The new €600 grant makes this a good time for homeowners to look at whether battery storage could make sense for their home.
Whether you’re installing Solar PV for the first time or already have panels and are considering adding a battery, the right system will depend on your electricity usage, existing installation and future energy requirements.
With 20 years in business and more than 25,000 solar installations completed across Ireland, Activ8 Solar Energies can assess your home and recommend a solar and battery system suited to how you actually use electricity.
