Solar grants for business: Updates for Energia commercial customers

Energia welcomes the enhanced solar grants for business available through the government's Non-Domestic Microgen Grant scheme (NDMG).

The grant support scheme for solar panels has recently been updated by the government to cover a wide range of installation sizes. With this update, solar installations with capacity greater than 6 kWp up to 1,000 kWp (1 MW) are now eligible for solar grants for business. This expanded eligibility supports small businesses and local shops as well as larger manufacturing companies and public facilities, such as community buildings and sports centres. Installations that go up to 1MW could be eligible for a grant of up to €162,600.

What is the Non-Domestic Microgen Grant?

The NDMG is the main government programme supporting solar grants for business in Ireland. Managed by the Sustainable Energy Authority of Ireland (SEAI), the scheme provides financial assistance to businesses and organisations installing solar PV panels to generate electricity on-site.

Through this scheme, companies can access commercial solar grants to help offset the upfront cost of solar panel systems while lowering long-term electricity costs and reducing carbon emissions.

The grant supports solar PV installations ranging from 1 kWp up to 1,000 kWp, enabling organisations of different sizes to access solar grants for business when investing in renewable energy solutions.

Grant amounts for Solar PV

The value of solar grants for business depends on the size of the solar PV system installed. The SEAI applies a tiered structure based on system output measured in kilowatt peak (kWp).

Typical grant levels include:

1 kWp: €900
2 kWp: €1,800
3 kWp: €2,100
4–6 kWp: €2,400
7–20 kWp: €300 per kWp
21–200 kWp: €200 per kWp
201–1,000 kWp: €150 per kWp

The maximum funding available through commercial solar grants is €162,600, depending on the system size installed.

For Energia commercial customers, it is strongly recommended that companies liaise with Energia if they are considering a Solar PV installation. In some cases, for large energy consumers, it may have an unintended impact on their energy bill. In order to mitigate any adverse consequences, Energia is available to guide customers in their transition to net zero carbon making sure that the best commercial option is always made available in the customer’s best interest.
