Solar on Your Farm

Solar Panels on Farmland

Two very different routes lead from "solar on my farm": lease your land to a developer for index-linked rent, or power your own farm to cut bills. Here's how each works, what you could earn, and whether your land qualifies.

Check If Your Land QualifiesCompare the Two Routes

Solar on Farmland: Quick Answer

There are two ways to put solar on a farm. Lease your land to a developer who builds a ground-mounted solar farm and pays you £850–£1,200 per acre per year, index-linked, for 25–40 years — passive income, no capital outlay. Or own the panels yourself, usually on barn roofs, to cut your own electricity bills. The leasing route is the bigger opportunity for most landowners, and it hinges on one thing above all: a grid connection with spare capacity near your land.

The Two Routes Compared

They suit very different goals. Most farmland-owner enquiries are about the first.

Lease your land

A developer builds and operates a utility-scale solar farm on your field and pays you rent. You take no capital risk and keep ownership of the land.

  • £850–£1,200/acre/year, index-linked
  • 25–40 year term; fully reversible after
  • No build cost or operating risk to you
  • Best for spare/lower-grade land near the grid

Power your own farm

You install panels, usually on barns and sheds, and use the electricity yourself to cut your bills. You fund it (or use a PPA) and own the output.

  • Best with high daytime use: dairy, cold store, drying, irrigation
  • Rooftop commercial solar is permitted development
  • Returns depend on how much you use on-site vs export
  • A PPA can fund it with no upfront cost

How a Solar Farm Sits on a Working Farm

Leasing land for solar doesn't mean giving up farming it entirely. A typical ground-mounted scheme uses around 40% of the site for panels, leaving margins, gaps between rows and buffer strips that are usually managed for nature or grazed.

Grazing continues

Sheep commonly graze under and around the panels — "agrivoltaics". The pros and cons guide covers dual-use in detail.

Biodiversity gain

Schemes must deliver Biodiversity Net Gain — wildflower margins, hedgerows, habitat. See the BNG guide.

Fully reversible

At lease end the panels are removed and the land returns to agriculture — usually with a decommissioning bond securing it.

Government policy backs this dual-use approach: England's Land Use Framework (18 March 2026) safeguards the best farmland while steering solar toward lower-grade land and shared use like grazing and agrivoltaics, and the Solar Roadmap (30 June 2025) estimates ground-mount solar would use up to about 0.4% of total UK land on the way to 45-47 GW by 2030.

How Much UK Farmland Do Solar Panels Use?

Less than the debate suggests. The UK has roughly 17 million hectares (about 42 million acres) of farmland. The government's Solar Roadmap puts ground-mounted solar at up to about 0.4% of total UK land by 2030 at 45 to 47 GW, and below 1% of agricultural land even at the higher 2035 ambition.

The land-quality question matters more than the total. Planning policy steers solar away from Best and Most Versatile land (Agricultural Land Classification Grades 1, 2 and 3a) and toward Grade 3b and below, and England's Land Use Framework (18 March 2026) reinforces that. A developer will ask for your ALC grade early; if you do not know it, the planning permission guide explains how to find it and what each grade means for consent.

REPD figures cover records updated between 2024-08-16 and 2026-08-16, and acreage is only recorded for some projects, so the total understates the true figure. County-by-county tables: UK solar farm planning data.

Can You Put Solar Panels on Agricultural Land?

Yes, but the rules differ by what you build and where.

Ground-mounted solar farm on a field

Needs full planning permission from the local planning authority; there is no permitted development route for a field-scale array. Since December 2025, schemes under 100 MW in England go through the local authority and only larger ones through the national (NSIP) process. The developer prepares and pays for the application. Grade 3b or lower land, screening from homes and roads, and a grid connection offer are what get it through. Details: solar farm planning permission.

Panels on barns, sheds and other farm buildings

Usually permitted development for non-domestic rooftops, subject to conditions (listed buildings, conservation areas and panels that overhang the roofline are the common exceptions). Check with the local authority before ordering.

Arable land specifically

Arable land can be converted to a solar farm with permission; the ALC grade decides how hard that is. Grade 3b and 4 arable land is routinely approved, Grades 1 to 3a face much tougher scrutiny. See land requirements for solar farms for the full checklist.

Solar Panels for Farms: Powering Your Own Operation

If the goal is a lower electricity bill rather than rent, the maths is the same as for any commercial building: how much of the generation you use on site. Dairies, cold stores, grain dryers, poultry sheds and irrigation pumps all have the daytime load that makes rooftop solar pay.

  • Size to your daytime load, not your roof. Exported power earns a fraction of what imported power costs.
  • A PPA for farms lets a funder own the panels and sell you the power below grid rates, with no capital outlay. See the PPA guide.
  • Check the export limit before sizing: a farm on a single-phase or weak three-phase supply may be capped by the DNO. The G98 vs G99 guide covers the thresholds.

Is Your Farmland Suitable?

Four things decide whether a developer will be interested. The first matters more than all the others combined.

1

Grid proximity — distance to a substation with spare capacity is make-or-break. This is what our free checker tells you instantly.

2

Size — roughly 25+ acres for a commercial scheme, though a well-connected smaller site can still work.

3

Land grade — lower-grade land (Grade 3b and below) is preferred and far easier to get through planning.

4

Topography & access — flat or south-facing, not heavily flood-prone, with vehicle access. Full land requirements checklist.

Income, Planning & Tax — Where to Go Next

If the leasing route fits, these are the pieces to understand before committing:

Income per acre →

Current lease rates, battery premiums and how RPI indexation compounds.

Tax implications →

Why a lease affects APR/inheritance tax — and why timing matters before you sign.

Sell or lease? →

Should you take a lump sum and sell, or lease for long-term income? The trade-offs compared.

Solar Panels on Farmland FAQs

Frequently Asked Questions

Usually yes, by one of two routes. You can lease your land to a solar developer who builds and operates a ground-mounted solar farm and pays you index-linked rent (typically £850–£1,200 per acre per year) — you do nothing and take no capital risk. Or you can install your own panels, normally on barns and farm buildings, to cut your own electricity bills. Both depend on a viable grid connection nearby; ground-mounted solar farms over roughly 1MW also need planning permission.
Leasing land to a developer for a solar farm typically pays £850–£1,200 per acre per year, index-linked, on a 25–40 year lease — several times higher than a typical agricultural rent. Battery storage on the site can add more. The exact figure depends on grid proximity, land quality and competition for the site. See our solar farm income per acre guide for current rates and worked examples.
Not entirely. A solar farm typically occupies around 40% of the leased area with panels, and the rest — margins, between rows, buffer strips — is often managed for biodiversity or grazed. Sheep grazing under and around the panels (a form of agrivoltaics) is common. The land is also reversible: at the end of the lease the panels are removed and the land restored to agriculture. It will not, however, qualify as actively farmed land for tax purposes while it's let.
Developers generally want from around 25–30 acres upward for a commercial solar farm, with larger sites (40+ acres) more attractive. The single biggest factor is not size but proximity to a grid connection point with spare capacity — a smaller well-connected site can beat a large remote one. Lower-grade agricultural land (Grade 3b and below) is also preferred for planning. See our land requirements checklist.
If you have high daytime electricity use — refrigeration, grain drying, dairy, irrigation, workshops — rooftop solar on barns and sheds can cut your energy bills significantly, and rooftop commercial solar is permitted development (no planning permission needed). The economics depend on how much of the generation you use on-site versus export. Note that on-farm solar can affect the agricultural business-rates exemption if most electricity is exported.
Very little. The government's Solar Roadmap (June 2025) puts ground-mounted solar at up to about 0.4% of total UK land by 2030 at 45-47 GW, and below 1% of agricultural land even at the higher 2035 ambition. The UK has roughly 17 million hectares (42 million acres) of farmland. Planning records for the last 24 months (DESNZ REPD) show about 187,779 acres of grid-scale solar approved or in planning where site area is reported, which is 0.45% of UK farmland. Our UK solar farm planning data page has the live county-by-county figures.
Yes. A power purchase agreement (PPA) lets a funder install and own panels on farm buildings and sell you the electricity at a fixed price per kWh below the grid rate, usually for 15 to 25 years, with no capital cost to the farm. It suits farms with steady daytime demand such as dairies, cold stores and grain drying. Leasing a field to a solar farm developer is a different arrangement: there the developer exports to the grid and pays you rent, not cheaper power. See our PPA guide for how the pricing works.
Leasing land for a solar farm has significant tax consequences: it usually loses Agricultural Property Relief for inheritance tax, the rent is taxed as property income, and gifting the land afterwards generally loses CGT holdover relief. These are best addressed before you sign an option. See our solar farm tax guide — and take specialist advice.
