How is the SEAI Grant for Solar Panels Calculated

The size of the grant paid by the Sustainable Energy Authority of Ireland (SEAI) is based on the kilowatt peak (kWp) energy output of the solar array being installed on a property.

The kWp value of a solar PV system is the combined total of the power rating of the modules in the system, e.g 10 panels each 440W in strength is a 4.4kWp system size.

The domestic Solar PV Grant is valued at:

€700 per kWp up to 2kWp
€200 per kWp up to 4kWp

This brings the maximum grant to €1,800 for a home in Ireland in 2025.

Number of Solar Panels	Solar PV System Output	Grant Value
4 panels	1.74kWp	€1,218
6 panels	2.61kWp	€1,522
8 panels	3.48kWp	€1,698
10 panels	4.35kWp	€1,800
12 panels	5.22kWp	€1,800
16 panels	6.96kWp	€1,800

The grant applies to the cost of all components and the installation of the solar PV system, such as the solar panels and the inverter. There is no separate or increased grant funding for other solar products such as a power diverter or battery storage.

FAQs

Is planning permission needed for the solar panel grant

Planning permission is not needed before applying for the SEAI solar electricity grant, as it isn’t something which they take into consideration for the grant approval process.

However, depending on the size of the solar system being installed, and the location of your home, farm, or business, you may still need planning permission to install solar panels in Ireland.

The VAT rate for domestic solar panels is 0%. This is true for the panels and all other equipment, and for the installation work itself.

Can I sell my surplus electricity from solar panels in Ireland?

Unused power generated by solar PV panels can be sold back to the national grid through a feed-in tariff rate set by your electricity supplier to earn even more from solar electricity.

Is there a grant for solar batteries?

The SEAI solar grant only covers solar PV panels, and there is no additional grant funding for solar battery storage.

Is the solar panel grant being removed?

The government has confirmed that it intends to further reduce the solar panel grant each year until it has been completely eliminated by 2029.

How long does it take for the SEAI solar grant to be paid?

The SEAI electricity grant for households takes 4 to 6 weeks to be paid after all of the documentation has been submitted. This might be higher if an inspection is required.

How many times can I claim the SEAI solar panels grant?
