Farms & rural business
Are solar panels worth it for farms and rural businesses in Scotland?
Yes. Farms and rural businesses benefit significantly from solar panels. Large agricultural roofs are ideal for PV, and high daytime electricity usage from dairy equipment, cold storage, and workshops means excellent self-consumption. A 10-50kW farm solar system can cut energy bills by 40-70% with payback in 5-8 years.
Why farms benefit
Why are farms ideal for solar panels?
Farms have large roofs, high daytime energy use, and land for ground-mount arrays — the three things that make solar most cost-effective. Agricultural buildings often have simple, unshaded roofs perfect for PV.
Large roofs
Barns and sheds offer 100-500m² of unshaded roof space
Daytime usage
Dairy, cold storage and workshops use energy when solar generates
5-8 year payback
Faster than residential due to higher usage and larger systems
Farms and rural businesses across Scotland face rising energy costs that directly impact margins. Solar PV is one of the most effective ways to reduce these costs long-term. Agricultural buildings — barns, livestock sheds, grain stores, pack houses — typically have large, simple roofs with excellent solar exposure.
The high daytime electricity usage on most farms means a large proportion of solar generation is consumed on-site rather than exported, maximising the value of every kWh generated. Where there's surplus, SEG export payments provide additional income.
System sizes & costs
How much do farm solar panels cost?
Farm solar systems range from 10kW to 50kW+. Costs scale with size: a 10kW system starts around £12,000-£15,000, while a 25kW system is typically £25,000-£35,000.
| System size | Typical cost | Annual output | Suitable for |
|---|---|---|---|
| 10kW | £12,000-£15,000 | ~8,500 kWh | Small farms / workshops |
| 25kW | £25,000-£35,000 | ~21,000 kWh | Dairy / mixed farms |
| 50kW | £45,000-£60,000 | ~42,000 kWh | Large farms / cold storage |
Costs are indicative ranges including 0% VAT and installation. Actual quotes depend on roof type, access, component choices and system complexity.
Battery storage for farms
Should farms add battery storage?
For farms with significant evening energy use — dairy milking, cold storage, heating — a battery is highly recommended. It stores daytime solar for evening operations and enables grid arbitrage.
Farm operations often run early morning and late evening — exactly when solar generation is lowest. A battery bridges this gap by storing peak midday generation for use during milking, feeding, or cold storage operation. For dairy farms in particular, a battery can transform the economics of solar.
Farm-scale batteries typically range from 15kWh to 100kWh depending on usage. See our battery storage guide for more detail, or our battery retrofit guide if you already have solar.
Farm battery systems qualify for 0% VAT until 31 March 2027, the same as residential installations.
Diversification
Can solar support farm diversification?
Yes. Solar can power EV charging points, farm shops, holiday lets, workshops, or processing facilities — turning excess generation into new revenue streams.
EV charging
Use solar to power EV charging points for farm vehicles, staff, or public charge points. Reduces fuel costs and supports the transition to electric farm transport.
Farm shops & cafes
Solar powers refrigeration, lighting and heating in farm shops and cafes — cutting operating costs for diversification enterprises.
Holiday lets
Holiday cottages and glamping sites benefit from solar by offering guests free or low-cost electricity while reducing your energy bills.
Processing & workshops
Solar can power farm processing equipment — milk pasteurisation, grain drying, wool processing — reducing the cost of adding value to farm produce.
Common questions
Frequently asked questions about solar for farms
Can farms get solar panels in Scotland?
Yes. Farms and rural businesses across Scotland can install solar PV on barns, outbuildings and fields. Agricultural buildings with large south-facing roofs are ideal for solar.
How much do solar panels cost for a farm?
Costs depend on system size. A 10kW farm system starts around £12,000-£15,000. Larger 25-50kW systems cost £25,000-£60,000. Finance is available, subject to status.
Can I get finance for farm solar panels?
Interest-free credit up to £30,000 is available, subject to status. For larger commercial systems, leasing and power purchase agreement (PPA) options may be available.
Do farms need planning permission for solar panels?
Roof-mounted solar on agricultural buildings usually falls under permitted development. Ground-mounted arrays over 9m² may need planning permission. Check with your local authority.
Can a farm battery store solar energy for night use?
Yes. Farm batteries store daytime solar generation for evening use — essential for dairy farms, cold storage, or any operation with significant overnight energy demand.
What about solar for farm diversification?
Solar can support diversification projects — EV charging, farm shops, holiday lets, or workshops. Excess generation can be exported for SEG income or used to offset rising energy costs.
