Commercial solar in Mid and East Antrim

Solar in Mid and East Antrim in figures

What the figures show

Capacity in Mid and East Antrim has grown by 113% since the end of 2020, faster than the UK as a whole (69%). In 2025 alone it rose from 26.9 MW to 28.1 MW.

There are 49.4 installations for every 1,000 households, close to the Northern Ireland median of 49.4 and below the UK median of 67.0. That is 259th of 361 council areas, and 6th of 11 in Northern Ireland.

The average installation is 10.4 kW, about twice a typical home system, so larger commercial, farm and ground-mounted systems make up a good share of the capacity.

What a business roof in Mid and East Antrim could generate

Modelled with PVGIS for the centre of Mid and East Antrim, a south-facing roof at 30 degrees produces about 858 kWh per kWp a year. That is 334th of 361 council areas; the UK median is 998 kWh.

Same sums as our commercial solar calculator: illustrative, not a quote. East- or west-facing roofs, shading and how much power you use in daylight all move these figures, and a company paying corporation tax can usually shorten the payback with capital allowances. See the cost guide for price ranges by system size.

Planning and grid connection

Planning in Northern Ireland is run mainly by the 11 councils, so Mid and East Antrim council decides most applications, with the Department for Infrastructure handling regionally significant ones. Rooftop solar on many non-domestic buildings can go ahead without an application, within limits. Our planning permission guide sets out the conditions.

NIE Networks runs the network across Northern Ireland, and systems connect under the G98/NI and G99/NI process. There is no Smart Export Guarantee in Northern Ireland, so sizing the system to the power you use on site matters even more.
