Solar Panels for Farms in Somerset

An independent guide to solar on farms in Somerset and the wider Somerset area, including Devon, Dorset, Wiltshire: what it costs, the planning rules, the grid and the funding position, from official sources.

Solar panels for farms across Somerset

Somerset is one of England’s most distinctive agricultural counties — 571,000 residents across 4,200 km² spanning the Somerset Levels and Moors in the west, the Mendip Hills and Polden ridge in the north, the Quantock Hills in the south-west, and intensive dairy and mixed farming throughout. The county supports around 5,200 active farm holdings working roughly 280,000 hectares of agricultural land, with dairy accounting for the largest single output (over 400 million litres annually) followed by beef, sheep, cider apples and a growing horticulture sector around Cheddar Vale.

MCS-certified installers deliver solar PV across the whole of Somerset — from the flood-managed Somerset Levels to the Mendip uplands, from West Somerset’s coastal smallholdings to the South Somerset arable belt around Yeovil. Every project should start with half-hourly meter data analysis and a structural roof survey or ground-mount geotech. SolarPanelsForFarms.uk is an independent guide, not an installer: enquiries from Taunton, Bridgwater, Yeovil, Frome, Wells, Glastonbury, Weston-super-Mare, Burnham-on-Sea, Minehead, Wellington, Chard, Crewkerne, Ilminster, Shepton Mallet, Street, Highbridge and the surrounding rural areas go to a matched MCS-certified installer covering the area, which returns a desk feasibility within 3 working days.

Where roof area runs out, the next question is land: the 1-acre solar farm appraisal.

Somerset’s farming landscape — where solar makes most sense

The Somerset Levels are the county’s defining agricultural feature: roughly 65,000 hectares of low-lying floodplain crisscrossed by the rhynes (drainage channels), the Rivers Tone, Parrett and Brue, and the King’s Sedgemoor Drain. Dairy farming dominates here — predominantly Friesian-Holstein and Jersey herds on improved pasture — alongside extensive willow growing for the famous Somerset basket-making heritage. Levels farms typically have substantial modern parlour and youngstock shed footprints (often 600–1,500 m² of single-span roof), making them excellent solar candidates despite ground-level flood-management constraints.

The Mendip Hills AONB in the north covers around 200 km² of upland farming — predominantly sheep and beef on the higher ground, dairy on lower south-facing slopes. AONB designation means roof-mounted PV on existing barns is still permitted development, but ground-mount arrays require full planning with landscape impact assessment. The Mendips have higher irradiance than the Levels (less Bristol Channel coastal cloud) — typically 1,050–1,100 kWh/kWp annually for south-facing systems.

The Quantock Hills AONB in the south-west is England’s first designated AONB and covers around 100 km². Farming here is dominated by sheep and beef on Exmoor-fringe upland with mixed enterprises in the lower vales. Conservation area sensitivity is high — installations must avoid skyline impacts.

The South Somerset belt around Yeovil, Wincanton and Castle Cary supports more intensive mixed farming — arable, dairy, beef, and the largest concentration of egg-laying poultry units in the county. Yeovil has historically been a major agricultural processing hub (cider, dairy, milling) and the surrounding farms are typically larger-acreage with high-baseload buildings.

Cheddar Vale is the centre of Somerset’s horticulture industry — protected cropping under glass and polytunnels, soft fruit (strawberries, raspberries), and salad leaf production for the major UK supermarkets. Energy intensity here is exceptional: a typical 4-hectare glasshouse can consume 1–3 GWh annually for supplementary lighting, climate control and pack-house refrigeration.

DNO grid connection in Somerset

Somerset is served primarily by National Grid Electricity Distribution (NGED, formerly WPD), covering the Levels, Quantocks, Mendips and South Somerset. NGED’s typical G99 application timeline runs 8–12 weeks for sub-200 kW systems and 12–20 weeks for larger commercial arrays. Rural three-phase reinforcement around Bridgwater, Highbridge and the Levels is currently moderately constrained — the planned grid upgrade in 2026–2028 will materially improve export capacity.

A small fringe of South Somerset near the Wiltshire border falls under SSEN, so each G98 (small) or G99 (large) application has to go to the right DNO. Where rural three-phase capacity is constrained, an export-limited system alongside battery storage is an option — most Somerset dairy and poultry farms have high enough self-consumption that export limitation rarely affects payback economics.

Somerset farming grants — what stacks

Somerset farms are in England, where no grant for solar panels on farms is open:

• Improving Farm Productivity grant (England) — closed. Round 2 paid up to 25% of eligible costs (for solar, £15,000 minimum to £100,000 maximum) for panels on farm-building rooftops or irrigation reservoirs only, with ground-based arrays excluded; it closed to full applications on 31 July 2025 and no further round has been announced. The Farming Equipment and Technology Fund’s 2026 window closed on 12 May 2026, and its item lists did not include solar panels to power a farm.
• Sustainable Farming Incentive (SFI) — has no solar items.
• Countryside Stewardship Capital Grants — the Capital Grants 2026 offer has no solar items.
• 100% Annual Investment Allowance — full first-year tax relief on capital up to £1m; most farms can deduct the whole cost of solar in year one.
• Smart Export Guarantee — pays for surplus exports, and each licensed supplier sets its own rate. SEG is particularly valuable for Levels dairy farms with strong summer surplus when cooling demand is lower.

Planning considerations in Somerset

Most agricultural roof-mounted solar in Somerset qualifies as permitted development under Class J (Part 14 of the GPDO 2015): no capacity limit, panels no more than 0.2 m proud of a pitched roof and at least 1 m from the roof edge, and the council’s prior approval on design and glare above 50 kW. The key exceptions:

• Buildings within the Mendip Hills AONB or Quantock Hills AONB — roof-mount still permitted on existing agricultural buildings but visual sensitivity reviewed by Somerset Council; ground-mount needs full planning with landscape and visual impact assessment.
• Listed farm buildings (common across the Mendips and around Glastonbury) need full planning and conservation officer engagement.
• Conservation areas in villages like Wedmore, Selworthy, Mells, North Cadbury — check whether the building is listed, since Class J excludes listed buildings.
• Somerset Levels and Moors Ramsar / SPA — wetland-designated land needs HRA screening for any ground-mount development; rooftop work generally unaffected.

Somerset Council operates a generally pragmatic planning service for agricultural renewables, with typical determination of 8 weeks for full applications.

Seasonal and irradiance profile

Somerset receives 1,050–1,100 kWh/m²/year of horizontal irradiance — higher than the UK average and among the best in England outside the south coast. The Bristol Channel coastal strip (Burnham, Weston) sees marginally lower yields due to sea-fret, while the inland Mendip and Quantock uplands deliver the strongest year-round generation. Summer yields are exceptional — June production can exceed 130 kWh/kWp in that month alone for well-sited arrays.

Dairy peak demand on the Levels coincides well with solar generation — twice-daily milking sessions (typical 5am and 3pm) bracket the strongest mid-day output, and bulk tank cooling is a continuous load. Battery storage is particularly valuable for Levels dairies to shift mid-day surplus into evening parlour use.

Arable farms in South Somerset see strongest economic returns from August–October solar generation aligning with grain drying demand. Horticulture in Cheddar Vale benefits from strong May–September yields aligning with peak ventilation and climate-control demand.

Frequently asked questions

Can I install solar panels on a farm in the Somerset Levels with flood risk?

Yes. Roof-mounted solar on existing farm buildings is unaffected by flood designation — rooftops sit well above any historic flood line and the panels themselves are weatherproof to IP67 standard. Ground-mounted arrays on the Levels typically need flood risk assessment and mounting frames specified for occasional inundation, but Levels farms have hosted multi-megawatt arrays successfully since 2015.

Which DNO handles my Somerset farm grid connection?

The vast majority of Somerset is covered by National Grid Electricity Distribution (NGED). A small fringe of South Somerset near the Wiltshire border falls under SSEN. The operator can be confirmed from your supply MPAN, and the G98 or G99 goes to the correct DNO. Typical timelines: 8–12 weeks for sub-200kW, 12–20 weeks for larger systems.

Does the Mendip Hills AONB designation prevent farm solar installation?

No. Roof-mounted PV on existing agricultural buildings within the AONB is still permitted development under Class J. Ground-mounted arrays need full planning permission with landscape and visual impact assessment, and the local planning authority (Somerset Council) generally supports well-designed schemes.

Do Somerset farms qualify for capital grants?

Not for solar panels at present. No England grant for solar panels on farms is open. Round 2 of the Improving Farm Productivity grant paid up to 25% of eligible costs — for solar, £15,000 minimum to £100,000 maximum — for panels on farm-building rooftops or irrigation reservoirs only, but it closed to full applications on 31 July 2025 and no further round has been announced. The Farming Equipment and Technology Fund’s 2026 window closed on 12 May 2026 and its item lists did not include solar panels to power a farm; Capital Grants 2026 and the Sustainable Farming Incentive have no solar items. Most farms can still deduct the whole cost in year one through the £1 million Annual Investment Allowance.

How much solar can a typical Somerset dairy farm install?

Most 100–300 cow Somerset dairies have parlour and youngstock shed roof areas of 400–1,200 m² — enough for 65–200 kWp of rooftop solar. Battery sizing typically lands at 30–80 kWh for self-consumption optimisation. For a cost benchmark, DESNZ Solar PV cost data for 2025/26 put the median installed price of a 10–50 kW system in Great Britain at £1,262 per kW, including VAT where charged and excluding batteries.

Can I combine solar with sheep grazing or pollinator-friendly planting under the panels?

Yes — this is called agrivoltaics and is increasingly common on Somerset Levels and Mendip-fringe farms. Sheep grazing under ground-mount panels works exceptionally well (panel mounting height 0.8–1.2m provides adequate sheep clearance), though the Sustainable Farming Incentive has no solar items. Pollinator-friendly wildflower seed mixes under panels deliver further biodiversity credentials.
