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.
Grid proximity — distance to a substation with spare capacity is make-or-break. This is what our free checker tells you instantly.
Size — roughly 25+ acres for a commercial scheme, though a well-connected smaller site can still work.
Land grade — lower-grade land (Grade 3b and below) is preferred and far easier to get through planning.
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.
Planning permission →
When it's needed, the agricultural land test, and why applications get refused.

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.
