Farm Solar Grants & Funding in 2026

Funding solar panels for agriculture in 2026

There is a persistent myth that the money for farm renewables dried up when the old feed-in tariff closed. It did not. The funding landscape for solar panels for agriculture in 2026 is arguably stronger than it has been in a decade, but it is built differently. Instead of one headline subsidy, the support comes from a stack: a universal tax relief that applies to almost every farm, an export tariff for the units you do not use, an environmental scheme that rewards dual land use, and devolved frameworks in Wales and Scotland that are often more generous than their England equivalents.

The catch is that no single route covers a whole project, and several are easy to miss. This guide walks through each in turn, with the realistic value range, so you know what to ask for. As always, the figures here are illustrative and depend on your structure, your land and your load.

The one that always applies: 100% Annual Investment Allowance

Start here, because it applies to almost every farm regardless of trading structure. Because HMRC treats a solar array as plant and machinery, the whole spend can be deducted from your first-year profit under the 100% Annual Investment Allowance, which shelters up to £1m of qualifying outlay each year. For a limited company that deduction is worth roughly a 25% effective tax saving in year one; partnership and sole-trader farms see a comparable benefit through self-assessment.

The practical point is that almost every farm rooftop install falls well within the £1m cap and is fully expensed immediately, rather than written down slowly over many years. That pulls the relief forward into the year you build, which is precisely when the cash matters most. You can read the detail on capital allowances at GOV.UK, and our cost guide shows how it reshapes payback.

The income stream: Smart Export Guarantee

The Smart Export Guarantee pays you for surplus units exported to the grid, on MCS-certified systems up to 5 MW, in the region of 4 to 15p per kWh. For most of UK commercial solar this is a minor line, because always-on businesses consume nearly everything they generate. On a farm it can be material.

The reason is the seasonal load profile. An arable holding whose biggest load is a grain dryer running hard for a few autumn weeks will export a great deal the rest of the year, so the SEG rate genuinely affects the return. It is worth shopping the export tariff rather than accepting the first offered, and worth modelling export income alongside self-consumption rather than treating it as an afterthought. You can find the scheme detail at the Ofgem Smart Export Guarantee pages.

The dual-land-use route: Sustainable Farming Incentive

This is the one farms most often misunderstand. The Sustainable Farming Incentive does not pay for standalone solar. There is no SFI action that simply funds panels on a shed.

What SFI can do is stack with a ground-mount scheme on the same land. Agrivoltaic arrays, solar above grazing or sheltering crops, leave the land in agricultural use, and the biodiversity and soil-health actions that earn SFI payments can run alongside the array. Relevant actions pay in the region of £500 to £5,000 or more per hectare per year. So the lease income from the ground-mount and the SFI payments for biodiversity actions can sit on the same acres at the same time. The 2025 SFI update is moving the scheme towards clearer renewable alignment, so this overlap is widening rather than narrowing.

The occasional helper: Farming Investment Fund

The Farming Investment Fund provides capital grants for productivity-improving investments in England, with awards from £500 up to £500,000. Solar is typically not eligible directly, which is why many farms dismiss it.

The value is indirect. Where solar is paired with an eligible item, a new grain dryer, a dairy parlour upgrade, there can be a route to support the broader project even if the panels themselves sit outside the grant. It is worth a check rather than an assumption, because the eligibility lists change between funding rounds.

Wales and Scotland: check your devolved scheme first

If your farm is in Wales or Scotland, do not benchmark against England. Both nations run their own grant frameworks, the Welsh Rural Investment Scheme and Sustainable Production Grant, and the Scottish Rural Development Programme, with farm-renewable support and intervention rates typically in the 10 to 40% range. These are often more generous than the England-wide equivalents, and they sit alongside the UK-wide AIA and SEG rather than replacing them. A Welsh or Scottish farm should review the devolved scheme specifically before assuming the support stops at the tax relief.

Stacking the routes: an illustrative example

Consider, as an illustrative composite based on typical UK arable projects and not a named client, a large family arable farm with around 12 acres of marginal pasture that crops poorly. Rather than buy a system outright, the farm leases the land to a UK developer for a 1.8 MW ground-mount array of roughly 3,300 panels generating about 1.7 million kWh a year. The lease runs 25 years at around £1,200 per acre per year with a built-in ratchet, the land continues to graze sheep, and SFI biodiversity actions stack with the lease income on the same acres.

In that single scheme the farm is using three of the routes above at once: the developer captures the export value, the lease delivers a reliable rent well above the arable rental it replaced, and SFI rewards the biodiversity actions layered on top. No capital changed hands on the farm’s side. The numbers depend entirely on the developer terms available in your region and your grid position, and we would never present a worked example as a guaranteed outcome for a different holding. The detail for cropping enterprises sits on our arable farms page.

How to make sure you claim everything you qualify for

The recurring mistake is treating funding as a single decision rather than a stack. A farm that takes only the AIA leaves SEG income and, on the right land, an SFI overlay on the table. A farm that chases a capital grant without checking indirect FIF eligibility on a paired item misses a route entirely. The order that works is: confirm the AIA position with your accountant, model SEG export income against self-consumption, test whether any land suits a ground-mount lease with an SFI overlay, and, in Wales or Scotland, open the devolved scheme before anything else.
