Agricultural properties represent some of the best solar opportunities in the UK. Large unshaded roof areas on barns and outbuildings, open land with excellent sun exposure, and high on-site electricity consumption from machinery, lighting, and refrigeration — farms are, in many ways, the ideal solar hosts. And unlike residential homeowners, farmers and landowners have access to a distinct set of funding routes designed specifically for rural and agricultural properties.
What Solar Funding Is Available for Farmers in the UK?
-
Farming Investment Fund — Farming Transformation Fund (FTF) — Provides capital grants for investments that significantly shift how farms operate. Solar installations that directly power farm operations (rather than primarily export to the grid) have been eligible under previous rounds. Grant rates and application windows vary — check the current Defra guidance for live rounds.
-
Farming Equipment and Technology Fund (FETF) — Covers specific equipment including some energy efficiency technologies. Eligibility changes with each funding round.
-
Rural England Prosperity Fund — Available in designated rural areas to support rural businesses, including farms, in investing in infrastructure and technology improvements including renewables.
-
Countryside Stewardship Scheme — Primarily focused on environmental land management, but some capital grants under this scheme cover energy-related infrastructure improvements on farm holdings.
-
0% VAT on agricultural solar — Business solar installations, including agricultural ones, also benefit from zero-rated VAT under current HMRC rules.
-
Business rates relief — Solar installations on agricultural buildings may qualify for business rates relief, reducing ongoing costs.
Does Defra Support Solar on Farmland?
Yes, though the framing matters. Defra and its devolved equivalents (including Rural Payments Agency in England) distinguish between solar that primarily serves on-farm energy needs and solar farms primarily generating for export. Grants under agricultural schemes are generally aimed at the former — installations that reduce the farm’s grid dependency and energy costs rather than large-scale commercial generation.
What About Solar Farms on Agricultural Land?
Larger ground-mounted arrays designed primarily for export — often called solar farms — fall outside most agricultural grant schemes and are assessed under commercial planning and grid connection frameworks. However, planning policy in England has been shifting to support dual-use “agrivoltaic” systems, where panels are installed at height to allow continued grazing or crop production beneath them.
Do Farmers Need Planning Permission for Solar Panels?
Roof-mounted solar on existing farm buildings often qualifies as permitted development, subject to conditions on size, position, and visual impact. Ground-mounted arrays above a certain size typically require a full planning application. In National Parks, Areas of Outstanding Natural Beauty, and other protected landscapes, stricter rules apply regardless of size.
What Battery Storage Options Suit Agricultural Properties?
Large-capacity battery systems are a natural fit for farms, which often have high but variable power demands. Options include:
-
Tesla Powerwall — Stackable units suited to properties with significant overnight loads
-
Fox ESS commercial batteries — Scalable systems that can be configured for high-demand agricultural settings
-
Duracell Energy batteries — Reliable storage solutions suited to properties wanting branded, trusted technology
-
Three-phase battery systems — Many farms and agricultural properties run three-phase electricity, and battery systems need to be correctly specified for this — something HomeKog’s engineers assess during survey
How Does Solar Help Reduce Farm Running Costs?
Farms are significant electricity consumers — cold storage, grain drying, milking equipment, water pumps, and EV or electric machinery charging all draw heavily from the grid. A well-sized solar and battery system can cover a substantial proportion of daytime consumption, and battery storage ensures overnight operations aren’t fully reliant on expensive grid power.
The Part Nobody Talks About: Solar as a Farm Diversification Strategy
Beyond energy cost reduction, solar gives farmers and landowners an additional income stream and long-term asset. Surplus generation exported via the Smart Export Guarantee creates a reliable secondary revenue. In the longer term, as battery technology improves and grid flexibility services expand, farm-based battery systems may be able to participate in demand-side response and virtual power plant schemes — earning additional income simply by charging and discharging at grid-beneficial times.
For landowners with non-agricultural land, lease agreements with solar farm developers represent another avenue — one that generates a steady annual income with no upfront investment required. Land lease rates for solar farms have risen significantly in recent years as developers compete for suitable sites.
Frequently Asked Questions
Q: Can a tenant farmer apply for solar grants, or does it have to be the landowner?
This depends on the grant scheme and the nature of the tenancy agreement. Some funding rounds require the applicant to own the property or have a long-term lease. It’s essential to check eligibility criteria for each scheme and, where relevant, agree any installation with the landowner in writing before applying.
Q: Can solar panels be installed on listed farm buildings?
Listed building consent is required for any alterations to listed structures, including solar panel installation. In practice, consent for solar on listed farm buildings can be difficult to obtain if it affects the character or appearance of the structure. It’s worth consulting your local planning authority before progressing.
Q: What grid connection do I need for a large farm solar system?
Larger systems — typically above 3.68kW single phase or above 11kW three phase — require a grid connection application with your local Distribution Network Operator (DNO). Connection timelines and costs vary by location and existing grid capacity. HomeKog can manage the DNO application process on your behalf.
