Farm diversification — Solar

Farm Solar Lease Calculator

Estimate annual rent, lifetime income and 40-year NPV from leasing land for a UK solar farm. Largely passive income — but it locks land up for decades.

Indicative figures only — do not rely on these for financial decisions.

This calculator uses generic UK assumptions for 2025–2026. Actual income, costs, planning prospects and tax depend heavily on your specific site, local market, and circumstances. Always take professional advice (planning consultant, accountant, surveyor) before committing capital or signing agreements.

Could selling a plot make more sense?

On the same 2.5 acres, releasing serviced plots to UK self-builders could return roughly £1,550,633 as one-off capital (~10 plots • 2.50 acres × £620,253/acre (Midlands)). Worth comparing against ongoing diversification income before you commit capex.

Upfront capex is what you have to spend before income starts (£0 for solar/battery — the developer funds it). 10-year net = NPV of 10 years of profit (5% discount) minus upfront capex; for one-off sales it's just the capital received. A negative number means the option doesn't pay back its capex within 10 years on these assumptions.

Solar lease reality check

Grid connection is everything. Even prime fields can be unviable if the local substation is full. Many UK developers will not progress sites without a firm grid offer or a clear path to one.
Most leases include grazing rights. Modern panels are designed for sheep grazing under and between rows — you can typically continue light grazing for the lease term.
Exit and decommissioning. Reputable developers post a decommissioning bond. Read the lease — some older leases left landowners exposed.
Inheritance tax shift. Land on a solar lease normally falls outside Agricultural Property Relief (it is not in agricultural use). It may instead qualify for Business Property Relief depending on structure. Take specialist advice before signing.
Planning is the developer's job — but not free. Negotiate that you are paid the option fee even if planning fails.

Solar lease FAQ

How much do farmers get paid per acre for solar in the UK?▾

2025–2026 typical lease rates are £850–£1,300 per acre per year for utility-scale schemes (5MW+), index-linked to RPI. Some prime sites with strong grid connections command £1,500/acre+. Smaller schemes (under 5MW) often command less per acre.

How long do solar leases run?▾

Typically 30–40 years from energisation, with break clauses negotiable. Add the 2–4 year option/development period before energisation.

Will a solar lease affect my Agricultural Property Relief?▾

Almost certainly. Land in solar use is not agricultural use, so APR is normally lost on the leased area. Whether Business Property Relief applies depends on lease structure and your overall holding. The IHT changes from April 2026 onwards make this even more important to get advice on.

Can I still farm leased solar land?▾

Modern bifacial-panel layouts are designed for sheep grazing and even some arable strip-cropping. Cattle and horses are usually excluded. Negotiate grazing rights into the lease — they are not automatic.

What about battery storage instead?▾

Battery storage (BESS) leases on small grid-adjacent footprints often pay £25k–£40k per MW per year — much higher £/acre than solar, but on a much smaller area. See the battery storage calculator for a comparison.

Is selling a plot for self-build a better option than a 40-year lease?▾

If your land has any planning prospect for housing, selling a single self-build plot can match 20+ years of solar rent as one-off capital — and you keep the rest of the farm in agricultural use. Compare both in the panel above.
