Solar panels for farms across County Down

County Down is one of Northern Ireland’s most diverse agricultural counties — from the intensive dairy and arable lowlands of the Lagan Valley, through the mixed enterprise farms of Lecale and Ards Peninsula, to the upland sheep and beef of the Mourne Mountains. The county’s 532,000 residents spread across Belfast’s eastern hinterland, the historic market towns of Newry, Downpatrick, Banbridge and Newtownards, and dozens of farming villages around Strangford Lough.

We deliver MCS-certified solar PV across the whole of County Down — for dairy, beef, sheep, arable, mixed and horticultural farms. Every project starts with half-hourly meter data analysis, NIE Networks grid connection assessment, DAERA Farm Energy Efficiency Scheme application and a fixed-price proposal within 7 working days. Our installation teams are dispatched from our Belfast partner hub, covering Newry, Banbridge, Bangor, Newtownards, Downpatrick, Castlewellan, Kilkeel, Warrenpoint, Comber, Saintfield, Crossgar and the Mourne foothills.

County Down’s farming landscape

The Lagan Valley in the north supports NI’s most intensive dairy and arable farming — modern Friesian-Holstein dairies milking 200–500 head, supplying Dale Farm, Lakeland Dairies and Glanbia. Average farm size is the largest in the county and the buildings are typically modern portal-frame parlours with substantial single-span roofs ideal for 80–250kWp installations.

The Ards Peninsula is a narrow coastal strip between Strangford Lough and the Irish Sea, with mixed dairy and arable on sheltered land. Strong solar irradiance (1,000+ kWh/kWp) and significant pack-house and storage infrastructure for the Comber and Greyabbey horticultural growing belt.

The Lecale region around Downpatrick supports mixed dairy and beef on glacial drumlin landscape — typically smaller farms (80–250 acres) but with strong commitment to direct sales, farm shops and added-value processing. Solar credentials matter commercially for farm-shop branding.

The Mourne foothills and Slieve Croob upland support extensive sheep and beef farming — Scottish Blackface and Suffolk-cross flocks on improved hill pasture. AONB designation across the Mournes constrains visual impact for ground-mount, but roof-mounted PV on existing barns is generally permitted development.

South Down towards Newry and Crossmaglen supports mixed dairy and arable on richer south-facing soils, with growing horticulture and poultry production near Banbridge.

Grid connection — NIE Networks

All County Down farm solar projects connect through NIE Networks. Typical timeline: 6–10 weeks for sub-100kW G98 applications, 10–16 weeks for G99 applications. The Mournes and Ards Peninsula areas have historically been moderately grid-constrained; the planned 2026–2028 reinforcement program improves export capacity for larger projects.

DAERA Farm Energy Efficiency Scheme

County Down farms qualify for DAERA Farm Energy Efficiency Scheme at up to 40% capital. The 2026 window opens spring with a 6–8 week application period. DAERA scoring favours high-energy dairy and poultry farms with strong baseload self-consumption. We have a 93% approval rate on County Down DAERA submissions.

Frequently asked questions

Do County Down farms qualify for FETF or other UK mainland grants?

No. FETF is England-only. County Down farms instead access the DAERA Farm Energy Efficiency Scheme which provides equivalent 40% capital support. We prepare DAERA applications on your behalf with a 93%+ approval rate.

Can I install solar on a Mournes AONB farm?

Yes. Roof-mounted PV on existing agricultural buildings within the Mournes AONB is generally permitted development. Ground-mounted arrays need full planning with landscape and visual impact assessment, but we have delivered ground-mount projects in the AONB. We manage the planning end-to-end.

How does NIE Networks compare to GB DNOs for connection timescales?

NIE timescales are broadly equivalent to mainland DNOs — 6–10 weeks for G98, 10–16 weeks for G99. NIE has invested in dedicated agricultural renewable energy capacity since 2022, materially improving response times.

Is solar viable on the Ards Peninsula given the coastal climate?

Yes. The Ards Peninsula actually has slightly higher annual irradiance than inland County Down (~1,020 kWh/kWp) due to lower cloud cover. Salt corrosion on coastal installations is managed with marine-grade mounting and inverter housings. We have completed installations within 200m of the coast successfully.
