Solar Panels for Farms in County Armagh

An independent guide to solar on farms in County Armagh and the wider County Armagh area, including County Down, County Tyrone, Republic of Ireland (Monaghan, Louth): what it costs, the planning rules, the grid and the funding position, from official sources.

Agricultural solar panels in County Armagh

County Armagh is Northern Ireland’s “Orchard County” — the most concentrated horticultural region in the province, where the Bramley apple orchards around Loughgall, Richhill and Portadown sit alongside intensive poultry, beef and dairy enterprises spread across the drumlins from Armagh city down to the South Armagh borderlands. Apple growing here is not a hobby crop: it is industrial-scale fruit production backed by grading lines, packing halls and refrigerated cold stores that hold Bramleys through the marketing season, and those cold stores run a continuous baseload that ordinary daytime solar generation matches almost perfectly. Add the broiler and processing weight of Moy Park around Craigavon and Portadown, plus the milk going off the Lurgan-side dairies, and you have a farming economy built on businesses that burn electricity twelve months a year rather than just at harvest. That steady, year-round demand is precisely why agricultural solar pays so well across this county.

Northern Ireland sits a little lower on the irradiance scale than the south of England, but a well-pitched east-to-west roof in mid-Ulster still produces roughly 850–950 kWh per installed kWp each year — and because grid-bought electricity in NI has climbed steeply, the value of every self-consumed unit has risen with it. The economics turn on what you use on-site: a poultry house ventilating sheds round the clock, an apple cold store holding 2–4°C, or a milking parlour running vacuum pumps and a plate cooler will self-consume the bulk of what the array makes, which is where the short paybacks come from. Every connection in the county is managed by NIE Networks, the distribution operator for the whole of Northern Ireland, and getting the grid application right is the single biggest determinant of how quickly a project moves from survey to switch-on.

Farms across the Irish Sea work to a different scheme — farm solar in Northern Ireland.

Farm solar across County Armagh by district

Different parts of the Orchard County run on different enterprises, and the right system size follows the dominant load. The table below gives representative ranges for the main farming districts.

The fastest paybacks belong to the poultry and cold-store operations whose load runs flat across the day and the year; mixed beef and sheep holdings in the south take longer simply because their consumption is more seasonal. A full breakdown of system sizing and pricing is set out on our agricultural solar panel cost page.

Grants and tax relief for County Armagh farms

County Armagh is in Northern Ireland, so the funding route is not the England-only Farming Equipment and Technology Fund — and no Northern Ireland scheme pays for solar panels. DAERA’s Sustainable Farming Investment Scheme did not list solar panels in its first round, which closed on 3 September 2026, and the Farm Business Improvement Scheme – Capital, delivered by the Department of Agriculture, Environment and Rural Affairs, closed in 2022 and excluded renewable energy. Northern Ireland also has no equivalent of the Smart Export Guarantee, so for the orchard cold stores, poultry sheds and intensive dairies that dominate Armagh, payback depends on how much of the output the farm uses itself.

Tax relief still applies: the 100% Annual Investment Allowance lets a profitable farm business write off the entire qualifying cost of a solar installation against taxable profits in the year of purchase, so a portion of the net spend comes straight back through reduced tax. Solar panels are special-rate plant, and a partnership with a company as a member cannot claim the allowance. The wider picture on funding is on our grants page.

Planning and grid in County Armagh

Planning turns on system size. Roof-mounted PV on existing agricultural buildings — poultry sheds, cold stores, parlours, machinery barns — is permitted development in Northern Ireland only as microgeneration: Part 37 covers systems up to 50 kW, and larger rooftop systems need planning permission. The county does contain designated landscape, most notably the Ring of Gullion AONB around Slieve Gullion in the south, and parts of the Lough Neagh shoreline carry environmental designations; any ground-mounted array — in an AONB or not — needs full planning permission with a landscape and visual impact assessment. South Armagh’s elevated drumlin sites attract closer scrutiny on visibility, so roof space is the better route there wherever the building stock allows.

On the grid side, every connection runs through NIE Networks. Smaller systems connect under the G98 process (broadly up to 16A per phase), while anything larger — which covers most poultry and cold-store installations — goes through a full G99 application and connection offer. The Craigavon, Portadown and Lurgan corridor generally has solid three-phase capacity, while rural single-phase supplies in South Armagh sometimes need reinforcement or an export limit. Ask the installer to run the NIE Networks application and G99 paperwork early, so the connection offer is known before the design is final.

Typical County Armagh farm solar projects

The systems installed across the county fall into a handful of representative bands. These are enterprise-type ranges, not specific named farms.

• Bramley orchard cold store / packing hall (Loughgall–Richhill belt): a 50–150 kWp roof array, often with a modest battery, to carry refrigeration and grading load through autumn and winter. There is no official Northern Ireland installed-price figure (DESNZ’s median of £1,262 per kW for 10–50 kW systems covers Great Britain only), and a near-continuous cold-store baseload keeps the share of output used on site — which payback depends on — high.

• Poultry broiler or laying unit (Portadown–Craigavon, Lough Neagh shore): the county’s fastest paybacks. Multi-shed ventilation, heating and lighting give a flat round-the-clock load that an 80–250 kWp system self-consumes almost entirely.

• Dairy parlour with battery (Lurgan and the Loughside): a 60–180 kWp parlour-roof array paired with storage to cover vacuum pumps and plate cooling through morning and evening milking. Self-consumption is high.

• Mixed beef, sheep and arable holding (Armagh city, Markethill, South Armagh): smaller 20–80 kWp systems sized to grain dryers, workshops and general yard load. More seasonal demand lowers the share of output used on site, which lengthens payback.

Every project begins with a free desk feasibility study from your half-hourly meter data, returned within 3 working days by a matched MCS-certified installer covering County Armagh; SolarPanelsForFarms.uk is an independent guide, not an installer.
