UK Farm Solar Install: Taking Control of Rising Energy Costs

The Problem: Grid-Only Power and a Power-Hungry Dryer

The farmer summarised the issue plainly: "The cost of energy going through the roof, and we just needed to find a line where we could just harness the cost of energy. That's our biggest issue now going forward."

The farm runs a dryer through the summer months and, before the install, had no on-site generation. Every unit powering the dryer was imported from the grid, exposing the business to rising wholesale prices and inflation with no buffer. As the farmer put it, "we have no other form of energy other than obviously utilizing the electricity off the grid."

For a working farm, that combination — a high seasonal load, a single energy source, and no price hedge — was the headline risk KMM was asked to address.

What KMM Did: A System Sized Around the Dryer Load

KMM's approach was consultancy-led rather than product-led. Before specifying panels, we mapped how and when the farm actually uses electricity — and the dryer, running through the sunniest months of the year, sat at the centre of that profile.

That alignment between solar generation and on-farm demand is the single biggest driver of return on a rural PV system. By sizing the array to feed the dryer during daytime operation, more of every generated kilowatt-hour is consumed on site at the full retail value of grid electricity, rather than exported at a lower rate.

The system was designed to: power the dryer directly on sunny days, reduce reliance on imported grid electricity year-round, and export any surplus generation under a Smart Export Guarantee tariff to create a secondary income line.

The Outcome in the Customer's Words

The farmer described the result in the language farms understand — stability and income, not just savings:

"If we've got sunny days, we can produce our own electricity that sort of drives the dryer unit and just help to sort of reduce costs. Having the solar on the farm is just that stability of trying to get a little bit of an income as well as utilizing that energy on the farm."

Three things changed for the business. The dryer now runs on self-generated power whenever the sun is shining, taking that load off the grid bill. The farm has a secondary income from exported electricity. And — the point the farmer kept returning to — there is now a hedge against the next round of energy inflation, instead of full exposure to it.

Why This Pattern Works for UK Farms

The dryer story is a textbook case for agricultural solar. Grain drying, ventilation, milking parlours, refrigeration and workshop loads all run during daylight hours, which is when a PV system generates. That means a farm typically self-consumes a far higher share of its solar than a domestic property does, and self-consumption — not export — is where the ROI lives.

Layer on the Annual Investment Allowance (AIA), which lets eligible businesses write off qualifying plant and machinery against taxable profits in the year of purchase, and the payback on a well-sized farm array is usually measured in single-digit years rather than decades. SEG export income then runs on top of that for the next 20+ years of panel life.

The farmer's own framing — "we just can't sustain where we're going at the moment" — is the reason we are seeing this conversation on farm after farm. Solar is no longer a green badge; it is operational risk management.

Thinking About Solar for Your Farm?

If your farm is running a dryer, parlour, refrigeration, ventilation or workshop load through daylight hours and watching grid costs climb, the maths is likely to work — but the system has to be sized around your actual demand profile, not a generic kW figure.

KMM will walk the site, model your half-hourly consumption, factor in AIA and SEG, and tell you honestly whether solar is the right answer for your holding. No pressure, no obligation.
