Ways to pay for farm solar
Interest-free credit up to £30,000, subject to status.
There are three common routes. Paying outright keeps things simple and suits farms with cash set aside for capital projects. Finance spreads the cost over an agreed term, which can make sense when you would rather keep working capital available for stock, feed or machinery. A mix of the two, with a deposit and the balance on finance, is also common. Whichever you choose, the system, the warranty and the quote stay the same.
Whether finance suits you depends on your cash flow, your other borrowing and your tax position. We set out the options alongside your quote, with no obligation to use them.
Interest-free credit of up to £30,000 is available, subject to status and affordability. Terms and conditions apply.
Capital allowances and tax relief
Solar panels, inverters and batteries on farm and business buildings may qualify as plant and machinery. That can make them eligible for capital allowances, including the Annual Investment Allowance, which lets a business deduct qualifying spending from taxable profits. The value depends entirely on your circumstances.
- Relief depends on your profits, tax rate and whether you trade as a sole trader, partnership or company.
- The timing of your purchase relative to your accounting year can matter.
- Always confirm with your accountant before relying on any tax treatment.
What shapes the value of a system
Rather than quote generic figures, we look at the factors that decide how well solar works for your farm:
- When you use electricity: power used on site during daylight is worth the most to you.
- Your unit rate: what you pay your supplier now and how your contract is structured.
- Installation work: roof condition, cable runs and any grid upgrades all affect the price.
- Export: surplus can be sold to a supplier on an export tariff, with rates that vary.
- Battery storage: can move midday surplus into early-morning or evening loads.
Your quote models these against your own bills, so the advice is specific to your farm rather than based on an average.
