Solar Panels for Farms in Berkshire

An independent guide to solar on farms in Berkshire and the wider Berkshire area, including Oxfordshire, Hampshire, Surrey: what it costs, the planning rules, the grid and the funding position, from official sources.

Agricultural solar panels in Berkshire

Berkshire is a compact, high-value farming county in the South East, where land economics make every kilowatt-hour count. The Royal County’s agriculture splits along its geography: mixed arable and sheep run across the chalk uplands of the North Wessex Downs, while dairy, equestrian and some horticulture cluster in the fertile Kennet and Thames valleys around Newbury, Hungerford and Reading. The Lambourn Valley — the “Valley of the Racehorse” — concentrates one of the densest populations of racehorse studs and training yards in the country, each running stables, lighting, water heating and increasingly horse-walker and solarium loads that draw power right through the day. Those daytime profiles are precisely what solar is built to serve.

Solar pays here for two reasons. First, the South East enjoys some of the strongest irradiance in the UK — roughly 1,000 to 1,050 kWh per kWp installed each year — so a Berkshire array generates noticeably more than the same kit in the north. Second, land and grid context favour rooftop generation: grain stores, livestock sheds, American barns and indoor schools offer large, unshaded south-facing roofs, and self-consuming that power displaces grid electricity that has only grown more expensive. The local distribution network operator is SSEN (Scottish and Southern Electricity Networks), which manages the poles, lines and connection process across the whole county. For cost, DESNZ’s Solar PV cost data for 2025/26 put the median installed price of a 10–50 kW system at £1,262 per kW in Great Britain (including VAT where charged, excluding batteries). How quickly a well-sized Berkshire farm array pays back depends on how much of the output the farm uses itself, and it then delivers two decades of near-free daytime power.

Farm solar across Berkshire by district

The right system size depends far more on enterprise type than on which market town you farm near. The table below shows representative patterns across the county’s main agricultural districts.

These are starting points. Size a Berkshire system from your actual half-hourly meter data so the array matches your real daytime demand rather than a generic rule of thumb — see our agricultural solar panel cost breakdown for how the figures are built up.

Grants and tax relief for Berkshire farms

Berkshire farms fall under the English schemes, and none currently pays for farm solar. Round 2 of the Improving Farm Productivity (IFP) grant paid up to 25% of eligible costs — for solar, £15,000 minimum to £100,000 maximum — for rooftop panels on farm buildings or on irrigation reservoirs, never ground-based arrays; full applications closed on 31 July 2025 and no further round has been announced. The Farming Equipment and Technology Fund (FETF) 2026 window closed at midday on 12 May 2026, its 2023–2026 item lists did not include solar panels to power a farm, and Capital Grants 2026 and the Sustainable Farming Incentive have no solar items.

The reliable saving is in the tax system. Solar panels are special-rate plant, and the 100% Annual Investment Allowance (AIA) lets most farm businesses deduct the full cost of a qualifying solar installation against taxable profits in the year of purchase. On top of generation, the Smart Export Guarantee (SEG) pays for surplus electricity exported to the grid through SSEN’s network, turning unused summer production into income rather than waste. Our grants and funding guide covers the current position in full; payback depends on how much of the output the farm uses itself.

Planning and grid in Berkshire

For the overwhelming majority of Berkshire farms, planning is straightforward. Rooftop solar on existing agricultural buildings — grain stores, livestock sheds, indoor schools, barns — generally falls under permitted development rights (Class J, Part 14 of the GPDO 2015): no capacity limit, provided the panels stand no more than 0.2 m proud of a pitched roof and at least 1 m from the roof edge, with the council’s prior approval on design and glare above 50 kW. That covers most of what farms in the Kennet and Thames valleys actually need.

Sensitivities arise with landscape. The North Wessex Downs National Landscape (AONB) covers a large swathe of west Berkshire around Lambourn, Hungerford and the downs, and the Chilterns National Landscape touches the county’s north-east. Ground-mounted arrays within these designated areas, or any scheme visible from them, will face closer scrutiny and usually require a planning application supported by a Landscape and Visual Impact Assessment (LVIA); rooftop schemes are far less contentious. Class J does not cover listed buildings or buildings within their curtilage — common around Windsor and the historic market towns — so panels on them need planning permission and listed building consent. A conservation area does not remove Class J rights for roof panels; there the restriction is on panels fixed to a wall that fronts a highway. On the grid side, SSEN (Scottish and Southern Electricity Networks) governs connections: smaller systems connect under the G98 fast-track notification, while most commercial farm arrays go through the G99 application process, where SSEN confirms what your local network can accept and whether an export limiter is needed. Ask the installer to handle the G99 paperwork and DNO liaison as part of the quote.

Typical Berkshire farm solar projects

The examples below are representative enterprise types and ranges, not specific named farms — your own figures depend on roof area, demand profile and tariff.

• A 200-cow dairy in the Kennet valley near Thatcham: parlour, bulk tank cooling, vacuum pumps and water heating create a strong daytime base load. A 75-120 kWp roof array on the cubicle shed and dairy can displace the bulk of daytime grid demand.

• A Lambourn racehorse stud and training yard: lighting, solariums, horse-walkers, water heating and office loads run through the working day. A 30-60 kWp array on stable and barn roofs gives quiet, fume-free generation that suits a yard environment.

• A mixed arable and sheep farm on the North Wessex Downs near Hungerford: grain drying and store ventilation drive seasonal peaks, while general farm and workshop loads run year-round. A 50-150 kWp grain-store roof system suits this profile, with a battery worth modelling to shift harvest-season generation.

• An equestrian and smallholding enterprise near Maidenhead or Windsor: indoor school lighting, yard power and a farmhouse give a mixed but daytime-weighted profile. A 20-50 kWp array fits it, with surplus summer output earning under the SEG.

Every Berkshire enquiry starts with your half-hourly meter data: SolarPanelsForFarms.uk is an independent guide, not an installer: send your details through the quote form and we will reply by email. A system designed around your actual load earns from the first day it switches on.
