Commercial solar in Causeway Coast and Glens

Solar in Causeway Coast and Glens in figures

What the figures show

Capacity in Causeway Coast and Glens has grown by 30% since the end of 2020, slower than the UK as a whole (69%). It barely moved in 2025 (from 74.4 MW to 75.6 MW).

There are 52.4 installations for every 1,000 households, above the Northern Ireland median of 49.4 and below the UK median of 67.0. That is 245th of 361 council areas, and 4th of 11 in Northern Ireland.

The average installation is 24.5 kW, several times a typical home system of about 4 kW, so solar farms and large commercial or farm roofs make up much of the capacity here.

What a business roof in Causeway Coast and Glens could generate

Modelled with PVGIS for the centre of Causeway Coast and Glens, a south-facing roof at 30 degrees produces about 859 kWh per kWp a year. That is 332nd 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 Causeway Coast and Glens 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.
