Barn + ground-mount
Cattle barns, grain stores, poultry sheds all suit roof-mount; underused arable land suits ground-mount.

Solar Power Purchase Agreements for farms & agriculture
UK farms — dairy, poultry, pig, arable — are uniquely well placed for PPAs: large barn roofs, ground-mount land availability where wanted, and Defra grant stacking opportunities. The 2026 Farming Investment Fund actively encourages PPA-funded solar.
Quick answer: solar PPAs for farms & agriculture
A solar PPA for farms & agriculture in 2026 typically prices at 10–14 p/kWh in year one on a 100kWp–5MWp system, versus 21–25 p/kWh grid import. The provider funds, owns and maintains the system for 15–25 years and you buy only the power it generates — no capital outlay. Typical year-1 saving: £8k–£500k.
| 2026 typical PPA profile — farms & agriculture | |
|---|---|
| System size | 100kWp–5MWp |
| Year-1 PPA tariff | 10–14 p/kWh (ground-mount cheaper) |
| Demand-PV match | Variable — dairy strong, arable weaker |
| Annual saving range | £8k–£500k |
Five drivers of PPA economics in farms & agriculture
Dairy load profile
Robotic milking + chilling + ventilation = 24/7 high daytime load.
Farming Investment Fund
Defra grant stacking with PPA possible on capex element.
Diversification income
Roof rental income stream in addition to solar savings.
Sub-verticals within farms & agriculture
Every sub-vertical inside this sector has slightly different PPA economics — load profile, roof type, covenant strength all vary.
Dairy farms
Highest self-consumption within farming — robotic milking + chilling + ventilation = 24/7 high daytime load.
Poultry farms
Continuous ventilation + lighting = strong PV match. Long roof shapes accommodate large systems.
Pig farms
Heating + ventilation — daytime load good. PPA combined with anaerobic digestion stack increasingly common.
Arable & mixed farms
Lower farm-load; export-heavy PPA structures. Grain drying provides seasonal peak coincident with summer PV.
Glasshouse / horticulture
Heating + lighting load; combined heat-pump + PPA stack gives 60-80% gas displacement.
Equestrian centres
Lights + arena + clubhouse load; mid-size systems often easier to plan than larger farm installations.

Funding a farms & agriculture solar system: PPA vs the alternatives
How a PPA compares with the other routes a farms & agriculture business can use to fund solar:
| Route | Upfront | Who owns & maintains | Best when |
|---|---|---|---|
| Solar PPA | £0 | Provider | No capital; want predictable 10–14 p/kWh power, off balance sheet |
| Cash / CapEx | Full system cost | You | Capital available; want lowest lifetime cost + 100% AIA in year one |
| Lease / asset finance | £0 down | You (after term) | Want eventual ownership but spread the cost |
| Grant-funded | Part-funded | You | You qualify for sector grant funding (often public sector) |

Farm PPA: solar power purchase agreements for agricultural businesses
A farm PPA puts solar on your barn roofs or spare land at no capital cost — the provider owns and maintains the system and you buy the electricity at a fixed 10–14 p/kWh (lower again for ground-mount). For dairy, poultry and pig farms the 24/7 daytime load from milking, chilling and ventilation gives exceptional self-consumption, so a PPA for an agricultural business in the UK typically delivers a strong year-1 saving with no asset on your balance sheet.
Typical agricultural deals run 100 kWp–5 MWp at 10–14 p/kWh. See the 145 kWp Lincolnshire dairy farm case study and 2026 PPA rates for tariffs by size.
Watch-outs specific to farms & agriculture
- Asbestos roofs: many older barns have asbestos — must be replaced before solar installation. £15-25k/m² impact.
- Wildlife / SSSI: ground-mount near protected sites needs habitats assessment.
- AAONB / National Park: ground-mount in protected landscapes often requires very specific siting.
FAQs
PPA FAQs — Farms & Agriculture
What is a farm PPA?
A farm PPA (agricultural power purchase agreement) is a contract under which a provider funds, owns and operates solar PV on your barn roofs or land and sells you the electricity at a fixed price per kWh — typically 10–14 p/kWh, versus 21–25 p/kWh from the grid — over a 20–25 year term, with no upfront cost to the farm.
Can I get a PPA for an agricultural business in the UK?
Yes. UK farms — dairy, poultry, pig, arable and horticulture — are well suited to PPAs thanks to large barn roofs, available ground-mount land and strong daytime load. Dairy and poultry farms see the highest self-consumption. Grant stacking with the Farming Investment Fund is sometimes possible on the capex element.
What's the typical PPA tariff for farms & agriculture in 2026?
Indicative 2026 tariffs for farms & agriculture range 10–14 p/kWh (ground-mount cheaper). The lower end applies to investment-grade off-takers on 25-year contracts with strong daytime self-consumption; the upper end applies to smaller systems or shorter terms. Our PPA calculator models your specific site.
How long does the PPA setup take?
From first call to commissioning typically 6-12 months. Indicative tariff in 2-4 weeks, site survey + heads-of-terms in 4-8 weeks, full contract in 8-12 weeks, build in 6-16 weeks. Larger systems with DNO upgrades take longer.
What system size suits farms & agriculture?
Typical 2026 systems for farms & agriculture range 100kWp–5MWp. Smaller sites stack with battery storage; larger sites may split across rooftop + ground-mount or multi-site sleeved structures.
Are there grant alternatives that beat PPA?
Grant capital can beat a PPA on lifetime cost, but check the window is actually open before you plan around it. The main public-sector route, the Public Sector Decarbonisation Scheme, has had no open application window since Phase 4 closed in November 2024 — and even while it was open it was heat-led, so solar qualified only alongside a fossil-fuel heating replacement in the same building. The Industrial Energy Transformation Fund, once the route for energy-intensive manufacturers, closed in July 2025 with no successor fund. For most commercial buyers a PPA wins on cashflow and admin simplicity, and it is deployable now rather than contingent on a future phase. See PPA vs grant-funded.
What's the off-taker covenant requirement?
Most providers want investment-grade or strong-unrated covenant. For weaker covenants, parent guarantees, letters of credit, or shorter contracts can bridge. See off-taker covenant deep-dive.

Get an indicative PPA tariffRobotic milking and chilling produce exactly the round-the-clock load funders like to see, and a 145 kWp dairy worked example shows how battery storage was added to cover night-time demand and supply interruptions.
Where land is available rather than roof, the economics change again — 5 MWp ground-mount cost and tariff covers the 8–11 p/kWh band and the connection and planning timelines that come with it.
Farm arrays span an unusually wide range, from a single poultry shed to a ground-mount scheme, and PPA cost by system size gives indicative capex, generation and tariff for each band.
Once a scheme runs beyond the barn roof onto adjoining land, 1 MWp ground-mount PPA pricing is the right benchmark to work from.
Farm deals add a land element most rooftop contracts do not, so read who owns the system and the land rights before granting any lease or easement.
