Why crop farms are ideal candidates for solar
Crop farming across the UK encompasses a diverse range of operations from large-scale cereal production to specialist vegetable growing and root crop cultivation. Whatever your crop focus, energy costs are an increasingly significant factor in production economics. Solar panels offer crop farmers a reliable way to control these costs while generating additional income from excess electricity. Grain drying represents the single largest energy expense for many crop farms. During harvest season, grain dryers can consume more electricity in a few weeks than the rest of the farm uses in an entire year. This extreme seasonal spike in energy demand coincides perfectly with peak solar generation in late summer and early autumn, making solar an ideal energy source for grain drying operations. Irrigation is another major energy consumer, particularly for vegetable and root crop operations. Electric pump systems for centre pivots, drip irrigation, and overhead sprinkler systems require substantial power during the growing season. Solar-powered irrigation benefits from the same seasonal alignment – sunny weather drives both energy generation and crop water demand. Crop storage facilities including potato stores, onion stores, and vegetable cold rooms require year-round power for ventilation, cooling, and humidity control. These consistent energy demands make excellent base loads for solar systems, ensuring high self-consumption ratios and maximum savings throughout the year. Modern crop farming increasingly relies on precision agriculture technology including GPS-guided equipment, remote sensing, and data analytics. These systems require reliable power for base stations, data processing, and communication networks. Solar-powered precision agriculture reduces the cost of technology adoption while supporting the data-driven farming approaches that improve yields and reduce input costs. The large-scale infrastructure typical of crop farms provides ideal solar installation surfaces. Grain stores, machinery sheds, drying facilities, and workshop buildings often have extensive south-facing roof areas that can accommodate substantial solar arrays with minimal structural modification.
What a typical crop farms installation looks like
| Typical system size | 50–400 kW |
| Project value | £45k–£350k |
| Simple payback | 4.5 years |
| FETF grant eligible | Yes (up to 40% capital) |
| MCS certified | All installs |
Benefits for crop farms
- Power grain drying during peak harvest demand
- Solar generation peaks align with irrigation needs
- Reduce crop storage ventilation and cooling costs
- Support precision agriculture technology systems
- Large farm building roofs ideal for solar installation
- Income from excess energy export during off-peak periods
- Protection against seasonal energy cost spikes
- Improved overall crop production economics
Grants and finance
The Farming Equipment and Technology Fund (FETF) is the primary capital grant route for agricultural solar in England, covering up to 40% of installation cost on eligible systems. Welsh Government Farm Business Grant, Scottish CARES loans, and Northern Ireland’s Farm Energy Efficiency Scheme are equivalent routes in the devolved nations. Capital allowances let you write down 100% of the residual investment against profits in year one under the Annual Investment Allowance (£1m cap).
For zero-upfront installs, we offer Power Purchase Agreement (PPA) finance where you pay only for the electricity generated at a rate well below your current grid tariff. Asset finance arrangements over 5–10 years are also widely available for farms with strong cash flow.
Compliance and structural points specific to crop farms
Most crop farms solar projects use permitted development rights under Class A or Class B of Schedule 2 of the GPDO, provided the system is below 1 MW and on existing agricultural buildings. Listed buildings, conservation areas, AONBs and National Parks require full planning. We handle every application — typical determination 6–8 weeks.
Structural surveys check purlin spacing, rafter capacity and roof sheet condition before any install. Asbestos cement roofing — still common on older sheds — is replaced as part of the project (licensed removal included). 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.
