Farm solar panels across Wiltshire
We survey farm and agricultural building roofs throughout Wiltshire, model what each one can carry, and arrange the design, the grid application and the install through our MCS-certified partner.

What the data says about Wiltshire
Modelled yield is not flat across Wiltshire. Salisbury comes out at 923 kWh per kWp a year against 894 at Chippenham, a spread of 29 kWh per kWp. On a 200 kWp farm array that difference is about 5,800 kWh a year, which is worth checking before accepting a generic saving figure.
Across the districts we cover in Wiltshire the planning record lists 25 ground mounted and 10 roof mounted solar schemes. Ground mounted schemes tell you how the network here has treated field arrays; roof mounted ones are undercounted, because an array on a farm building rarely passes the reporting threshold. Source: Renewable Energy Planning Database, Q1 2026.
Connections across the county run through Scottish and Southern Electricity Networks. Anything above 3.68 kW per phase needs a G99 application, and on rural feeders the incoming supply is often the real limit: a single phase supply caps the array whatever the roof would carry.
