Barn + ground-mount
Cattle barns, grain stores, poultry sheds all suit roof-mount; underused arable land suits ground-mount.
Sector: Farms & Agriculture
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.
| 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 — robotic milking systems match PV almost perfectly.
Poultry farms
Continuous ventilation + lighting = strong PV match.
Pig farms
Heating + ventilation — daytime load good.
Arable & mixed farms
Lower farm-load; export-heavy PPA structures.
Glasshouse / horticulture
Heating + lighting load; combined heat-pump + PPA stack.
Equestrian centres
Lights + arena + clubhouse load; mid-size systems.
Case study
145kWp PPA on a Lincolnshire Dairy Farm
| System size | 145 kWp |
| PPA tariff | 13.5 p/kWh (year 1) |
| Contract term | 25 years |
| Year-1 saving | £14,500 |
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'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?
For public-sector sites, PSDS often gives a lower lifetime cost — but with lengthy procurement and 100% utilisation requirements. For energy-intensive industry, IETF stacks. For most commercial buyers, PPA wins on cashflow and admin simplicity. 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.
