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.

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 £600–£1,350 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.

  • £600–£1,350/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.

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.

Start With the One Thing That Decides It

Before anything else, find out whether there's grid capacity near your land. It's free, takes under a minute, and tells you if a solar lease is even on the table.

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 £600–£1,350 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 £600–£1,350 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.
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.
