solar panels for barns in Cumbria

Serving Cumbria and the wider Cumbria area, including Northumberland, County Durham, Lancashire.

Why Cumbria barn owners are turning roofs into income

Cumbria is upland farming country, and its barns are built for the weather. Across the fells and dales the signature building is the Lake District bank barn — set into a slope so that stock can be housed below and the threshing floor or hay store reached on the level above — alongside countless traditional stone barns serving the sheep and dairy farms that work this landscape. Down on the Solway Plain around Carlisle, and on the lower, kinder land of the Eden Valley and the Furness peninsula, the picture shifts towards larger mixed and dairy units carrying modern steel-portal sheds. It is a county defined by livestock, by stone, and by a lot of rain — but Cumbria still receives plenty of usable daylight, and barn solar economics depend far more on what a roof does with that generation than on peak summer sun.

The case for solar here is the same case that holds across the British countryside: a large, simple roof plane sitting idle while energy bills climb, paired with a real on-site load. A working Cumbrian dairy or livestock barn runs lighting, scrapers, water heating, milk cooling and parlour plant — loads that fall squarely in daylight hours, so most of what the panels make is used where it falls. That self-consumption is what drives the payback. Turn an unused south-facing roof near Penrith or Kendal into 30 years of generation and a maintenance liability starts earning its keep.

The barns we work on across Cumbria

Cumbria’s farms run heavily to livestock, and so does our work here. Cattle courts, cubicle housing and sheep sheds carry steady year-round loads, and dairy units add milk cooling and vacuum pumps that push self-consumption high — the profile behind our solar for livestock buildings work, where the electricity is used on site and the payback is among the fastest of any barn type. On the larger lowland holdings of the Eden Valley and the Solway, the modern steel-frame portal shed is the standard: engineered for the snow and wind loading these uplands demand, and almost always able to carry the modest added weight of panels with a straightforward structural sign-off. This is the territory of our solar for steel-frame portal barns work — a clear single span with no shading and a supply already on site.

The county’s older buildings are a different matter. Lake District bank barns and traditional stone field barns are the heritage of the fells, often with handsome but constrained slate roofs that call for a sensitive, discreet design rather than a standard array. And across Cumbria, barn conversions, stables and smallholdings — many near Kendal, Penrith and the National Park fringe — sit at the domestic end of the market, where a barn-sized roof feeds a heat pump, an EV charger and a home battery.

Planning and listed barns in Cumbria

For most working farm barns the planning route is simple. Rooftop solar on an agricultural building is normally Permitted Development under Class A, Part 14 of the GPDO 2015, provided the panels do not stand more than 0.2 m above the roof plane and the capacity and siting limits are met. No planning application is needed, and the bulk of Cumbria’s modern steel sheds and livestock buildings on the Solway, in the Eden Valley and around Furness fall neatly within it.

Cumbria carries an unusually high concentration of protected landscape, though, and that has to be said plainly. The Lake District National Park covers a vast swathe of the county and is also a UNESCO World Heritage Site; the Yorkshire Dales National Park extends across the eastern fells, and the North Pennines and Arnside & Silverdale National Landscapes (AONBs) add further coverage. Inside these designations Permitted Development is restricted, and a planning application may be required for a barn roof that would be permitted on the open plain. Layer on the listed status that attaches to many bank barns and traditional threshing barns, and the consenting route changes again — Permitted Development is removed, and Listed Building Consent becomes the path. None of this stops solar. It calls for a heritage statement, discreet siting on a secondary or rear slope, low-profile in-plane or all-black panels, and early conversation with the conservation officer; where a historic slate roof truly cannot take PV, a nearby ground-mount array is the honest alternative. We confirm exactly where your barn stands and handle any application as part of the job.

Grid connection across Cumbria

The distribution network operator for Cumbria is Electricity North West, and on a rural barn install the grid connection is usually the longest single item in the timeline. Almost every barn system exceeds 3.68 kW per phase, so a G99 application to Electricity North West is required before connection. On the long rural feeders that serve the fells, the dales and the more remote parts of the county, capacity can be constrained, and a connection study is often needed to confirm what the network will accept.

It is rarely a dead end, but it does shape the design. Where export capacity is limited, we size for self-consumption — a smaller, faster-payback system that uses most of its generation on site rather than competing for export headroom on a tight line. Adding a battery and an export limiter can turn a connection from a many-month wait into a matter of weeks. Cumbria’s livestock and dairy barns suit this approach particularly well, because their steady daytime load consumes the electricity where it is made. We submit the G99 application alongside the structural survey, so the DNO clock starts as early as possible.

What barn solar costs in Cumbria

Barn solar cost follows roof size and use, not farm acreage. A small traditional or converted-barn system in the 6–20 kW band runs roughly £7,000–£22,000. A working agricultural barn — a steel-portal shed or a livestock building at 30–200 kW — is typically £24,000–£185,000. Larger stores and multi-shed units at 200–500 kW reach £180,000–£450,000. Cost per kW falls as the system grows: around £900–£1,200/kW under 30 kW, £750–£950/kW from 50–250 kW, and £700–£850/kW above 300 kW.

As an illustrative scenario, a typical 60 kW array on an Eden Valley dairy barn might generate in the region of 54,000 kWh a year, with most of it consumed directly against the parlour’s milk-cooling and vacuum load — the kind of high self-consumption that supports a payback around the six-year mark. For a working barn owned by a trading farm business, 100% Annual Investment Allowance writes the cost off against tax in year one, and the Smart Export Guarantee pays for surplus. Scottish and Welsh schemes do not apply here, but English farms should check the funding routes set out on our grants and funding page alongside the worked ranges on our cost page.

Barn solar across Cumbria

We work with barn owners across the whole county, from the upland sheep and dairy farms of the Lakes and the Pennine fringe to the lowland holdings of the coast and the plains. Areas we serve include Carlisle and the Solway Plain, Penrith and the Eden Valley, Kendal and the southern dales, Workington and the west Cumbrian coast, and Barrow-in-Furness and the Furness peninsula. We also work readily across the boundaries into Northumberland, County Durham, Lancashire and North Yorkshire, where the same upland farming and the same barn types continue.

Whether you run a fell-side sheep unit above Kendal, a dairy herd in the Eden Valley near Penrith, or are converting a stone bank barn on the Lakeland fringe into a home, we start the same way: an honest desk assessment from your meter data and roof details before any talk of panels. If your barn does not suit solar, we will say so. If it does, get your free barn solar quote and we will return an indicative system size, generation forecast and payback for your roof.
