Ground-Mounted Solar for Scottish Farms

Ground-mounted solar for Scottish farms: field arrays and planning

Quick answer

When does a ground-mounted array make sense on a farm?

A ground-mounted array puts solar panels on frames in a field, ideal when farm roofs are fragile, shaded or too small. Panels can face due south at the best angle, and sheep can still graze beneath. Field arrays often need planning permission in Scotland, so site checks come first.

When a field array makes sense

Roof systems are usually the cheapest place to start, but they are not always possible. A ground-mounted array is worth considering when:

Roofs are fragile, asbestos cement, listed or heavily shaded.
Demand is larger than your roofs can meet, for example on grain drying or large dairy units.
You have a low-value field, a corner or a paddock close to your electrical supply.
You want the best possible yield, with panels set at the ideal tilt and facing due south.

Choosing the right field

Orientation and shading

A gentle south-facing slope is ideal. Trees, hedges, buildings and hills to the south cast long winter shadows at Scottish latitudes, so rows are spaced further apart than in southern England.

Distance to the connection point

The array has to be cabled back to your distribution board or a new connection. Long trenching runs add cost, so the closest suitable field often wins over the flattest.

Ground conditions and access

Frames are usually fixed with driven or screwed piles. Very rocky ground, peat or waterlogged fields can need different foundations. Installation vehicles need reasonable access in the build window.

Planning permission

Rooftop solar on agricultural buildings is usually permitted development, but ground-mounted arrays are assessed differently. Whether you need consent depends on the size of the array, its location, and any designations such as National Scenic Areas, conservation areas or nearby listed buildings. Your local council's planning team makes the decision.

We check the planning position before you commit and, where an application is needed, prepare the layout drawings and supporting information. Screening with existing hedges, keeping arrays low and avoiding skylines all help.

Land use: a field array can sit alongside farming. Sheep grazing under panels is common, and arrays can be designed for later removal, returning the field to full use.

Size, yield and connection

Field arrays can be set at the ideal tilt and orientation, which helps generation, and your quote includes a site-specific estimate. Larger arrays will almost always need a G99 application to your network operator, and in some rural areas an export limit or zero-export design. Pairing the array with battery storage can raise how much you use on site.

Frequently asked questions

How much land does a ground-mounted farm solar array need?

It depends on the system size, the slope and shape of the field, and the spacing needed between rows to avoid winter shading. North-facing or awkwardly shaped fields need more room. The survey confirms the exact layout for your site.

Do I need planning permission for a field solar array in Scotland?

Often, yes. Ground-mounted arrays on agricultural land are treated differently from roof systems, and whether permission is needed depends on size, location and site designations. We check the current position with your local planning authority before you commit.

Can sheep graze under solar panels?

Yes. Sheep grazing is common on ground-mounted arrays because it keeps grass down without machinery. Panels are mounted high enough for sheep to move underneath, and cabling is protected. Cattle and horses are generally not suitable, as they can damage frames.

What foundations do ground-mounted panels use?

Most frames are fixed with driven or screwed piles, which avoid large concrete pads and can be removed later. Very rocky ground, peat or waterlogged fields may need a different approach, which we identify at survey.

Is a field array better than a roof system?

Not always. Roofs avoid using land and usually need fewer groundworks, while field arrays can face due south at an ideal tilt and avoid fragile roofs. We compare both for your farm and recommend whichever fits your demand, land and grid connection.
