Why goat dairy farms are ideal candidates for solar
Goat dairy serves a specialist UK market, driven by consumer demand for artisan cheese, fresh chevre and speciality yoghurt. What makes goat dairy energy-intensive isn’t scale - it’s the value chain. Every litre of milk is processed on-farm, refrigerated, often pasteurised and frequently aged for months. That means a goat dairy’s electricity bill looks more like a small food factory’s than a conventional farm’s. Your milking parlour runs twice a day, your bulk tank cools continuously, and your cheese room or maturation cave holds a precise temperature year-round. Add a pasteuriser, a packing cold-store and the hot-water load for cleaning protocols, and it’s easy to see why electricity weighs so heavily on a goat dairy’s running costs. Solar suits your demand profile well. Cheese production runs during daylight hours, cooling loads peak on warm afternoons, and parlour roofs - often single-storey and structurally simple - can make good PV surfaces. A system sized from your half-hourly meter data can offset much of the daytime grid import for cooling, pasteurising and cleaning. EU PVGIS puts a south-facing 30° roof at about 1,045 kWh per kWp a year in Exeter and 963 in Shrewsbury. Beyond cost savings, solar credentials matter commercially. Premium retailers increasingly ask suppliers for Scope 3 emissions data, and a visible, MCS-certified solar installation gives you a concrete proof-point to report.

- £1m AIA: deduct the full cost in the year of purchase
Grants and finance
In England, the Improving Farm Productivity (IFP) grant funded 25% of eligible costs for rooftop solar and irrigation-reservoir solar only — ground-mounted arrays on land were not eligible. Round 2 has closed and no solar round is open at the time of writing (September 2026); Wales, Scotland and Northern Ireland run their own schemes. The £1m Annual Investment Allowance lets most farm businesses deduct the full cost in the year of purchase.
For zero-upfront installs, ask installers about Power Purchase Agreement (PPA) finance, where you pay only for the electricity generated at a rate below your current grid tariff. Asset finance over a fixed term suits farms with strong cash flow.
Compliance and structural points specific to goat dairy farms
In England, rooftop solar on dairy buildings is usually permitted development under Class J, with prior approval from the council on design and appearance above 50 kW; Class J does not apply to listed buildings or scheduled monuments. A stand-alone ground array over 9 m² needs full planning permission — see solar on farm buildings.
Structural surveys check purlin spacing, rafter capacity and roof sheet condition before any install. Asbestos cement roofing is always fragile and cannot bear weight, so avoid drilling through it: overclad with non-asbestos sheeting on the existing purlins, or remove and re-sheet; a whole roof needs a proper risk assessment and plan of work (asbestos roofs). Three-phase supply upgrades are handled with the local DNO (UKPN, NGED, SSEN, SP Energy Networks or Northern Powergrid).

Common questions
How much do solar panels for a farm cost in the UK?
Dairy and livestock parlour installs (30–250 kW): £32,000–£225,000. Arable rooftop installs (50–500 kW): £45,000–£500,000. Ground-mount agrivoltaic schemes (500 kW–10 MW): £350,000–£8m+. Cost per kW is typically £750–£1,000 for rooftop above 100 kW, £600–£800/kW for ground-mount above 500 kW.
What's the payback for a dairy farm solar install?
5–6 years. Dairy farms have outstanding self-consumption (24/7 milk cooling, parlour pumps, lighting) — often 90%+ of generation is consumed on site. Combined with 100% AIA tax relief, dairy installs sit alongside cold-chain warehouses as the fastest-payback segment in UK commercial solar.
Can we install solar on asbestos cement farm roofs?
No — asbestos cement roofs must be replaced first. The most common solution is a combined re-roof + PV install where the PV business case partially funds the re-roof. CAR 2012 governs asbestos handling — only licensed contractors can remove asbestos cement. Most modern installs sit on profiled steel re-clads.
What about agrivoltaics — solar above crops or grazing?
Agrivoltaics is emerging quickly in the UK. Sheep grazing under elevated panels is well-established. Crops (typically shade-tolerant: leafy greens, soft fruit, hops) under translucent panels is showing promising trial results. Defra and NFU are engaged. SFI 2025 is expected to add specific agrivoltaic compatibility actions.
What grants are available for farm solar?
100% AIA tax relief is universal. SFI actions support agrivoltaic schemes and biodiversity-stacked installs. Farming Investment Fund occasionally relevant. Welsh and Scottish farms have their own devolved schemes with often-higher intervention rates. SEG provides ongoing export income.
Do tenant farmers need landlord consent?
Yes — for any structural alteration to buildings or land use change. Most institutional landlords (Crown Estate, Church Commissioners, Wellcome Trust, county councils) have standard tenant-PV addenda. Private landlords vary. We provide the lease addendum template. Some landlords prefer to fund directly with a service-charge recovery from the tenant.
