Northern Ireland Farm Solar

Northern Irish farms — strong dairy, livestock and poultry sectors — are served by NIE Networks for grid connections. DAERA's Farm Energy Efficiency Scheme covers up to 40% of capital cost for qualifying renewable projects, and the Farm Business Improvement Scheme provides larger capital grants.

Farming landscape across Northern Ireland

Strong dairy concentration in County Down and County Antrim (highest UK dairy density). County Armagh — the "Orchard County" — leads UK Bramley apple production with pack-house and cold-store electricity demands. County Tyrone and Fermanagh upland beef, sheep and mixed. Poultry concentrated around Lough Neagh.

Grants and funding routes

DAERA Farm Energy Efficiency Scheme — 40% capital, annual spring window. NI Sustainable Land Management Scheme provides supplementary biodiversity funding.

Planning and protected landscapes

Mourne Mountains AONB, Sperrins AONB, Causeway Coast AONB, Antrim Coast & Glens AONB, Strangford & Lecale AONB. Planning devolved to DfI Planning. Most farm rooftop solar qualifies as permitted development.

Most Northern Ireland rooftop installations on existing agricultural buildings qualify as permitted development under Class A or Class B of the GPDO. Ground-mount and listed buildings need full planning. Your installer should handle the application — see planning permission for farm solar.

Grid connection — NIE Networks

NIE Networks. 6-10 weeks G98, 10-16 weeks G99. NI Government has invested in dedicated rural three-phase capacity since 2022, materially improving response times.

Every project we deliver in Northern Ireland goes through NIE Networks. A specialist installer manages G98 (sub-16A/phase) and G99 (commercial scale) applications end-to-end as part of the quote — see our 8-stage installation process for typical timings.

Climate and solar irradiance

Mild oceanic climate. Wet but with long growing season. Wind loading higher than England, particularly on the Causeway Coast. Salt exposure on Atlantic coastal sites.

Annual irradiance: 960 kWh/m²/yr — coastal sites (Ards Peninsula, Causeway) higher than inland.. This translates to 816 kWh per kWp of installed capacity per year for a south-facing 30° pitched roof — the figure we model every Northern Ireland farm quote against.
