Why horticultural farms & greenhouses are ideal candidates for solar
Horticultural farming and greenhouse operations represent some of the most energy-intensive forms of agriculture. Whether you’re growing vegetables, fruits, flowers, or plants in greenhouses, polytunnels, or controlled environment facilities, your success depends entirely on maintaining precise environmental conditions – and that requires enormous amounts of energy. Your heating bills alone can be staggering, especially during winter months when you’re maintaining growing temperatures while outside temperatures plummet. Add to that your ventilation systems, irrigation pumps, lighting systems for extending growing seasons, and cooling systems for summer temperature control, and energy costs can represent 15-25% of your total production expenses. The challenge is that you can’t compromise on environmental control without compromising your crops. A few degrees too cold and you lose tender plants, inadequate lighting and growth slows dramatically, insufficient ventilation and disease pressure increases. Your plants don’t understand energy prices – they just need the right conditions to thrive. Greenhouse operations are particularly well-suited to solar installations. Many greenhouses can accommodate semi-transparent solar panels that generate electricity while still allowing sufficient light for plant growth. This technology allows you to turn your greenhouse roof into a power generator without sacrificing growing space or light levels. For outdoor horticultural operations, packing sheds, cold storage facilities, and processing buildings provide excellent opportunities for traditional solar panel installations. These buildings often have large, unshaded roof areas perfect for maximizing solar energy generation. The timing alignment is particularly beneficial for horticultural operations. Summer cooling demands coincide with peak solar production, while battery storage systems can provide power for critical systems during cloudy periods or at night. Many horticultural businesses have achieved 50-70% reductions in energy costs, with some becoming net energy exporters during peak production periods. The sustainability credentials are increasingly important in horticulture, where consumers are becoming more conscious of the environmental impact of their food choices. Solar-powered growing operations can market their produce as sustainably grown, often commanding premium prices in environmentally conscious markets.

Benefits for horticultural farms & greenhouses
- Significant reduction in heating and cooling costs
- Semi-transparent panels for greenhouse applications
- Power for irrigation, ventilation, and lighting systems
- Sustainable growing credentials for premium markets
- Reduced operational costs improving profitability
- Energy independence for critical growing systems
- Utilization of large greenhouse and building roof areas
- Protection against volatile energy prices
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 horticultural farms & greenhouses
Most horticultural farms & greenhouses 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.
