Solar panels for farms in Warminster
Around Warminster the constraint is rarely the roof. It is the incoming supply and what the network will accept back. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.
912 kWh per kWp a year at this latitude, so a 500 kWp array models at about 456,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for agricultural buildings across Wiltshire
What a farm roof near Warminster generates
Modelled irradiation at this latitude is 1165 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 912 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 3 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.
The planning record lists 4 ground mounted solar schemes in this postcode district, which is a fair guide to how the local network has treated field arrays. The typical consented scheme in this district is about 12 MW, with the largest at 18 MW. Source: Renewable Energy Planning Database, Q1 2026.
1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Warminster is higher than the record shows.
Surveys run across BA postcodes, BA12 outward.
Wiltshire is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.
Warminster ranks 3 of 8 towns we cover in Wiltshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 894 to 923, a spread of 29 kWh per kWp. Within Wiltshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Grid connection through Scottish and Southern Electricity Networks
Connections around Warminster are handled by Scottish and Southern Electricity Networks, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a farm uses most of what the roof makes during the working day.
Across Wiltshire the planning database records 159 solar schemes totalling 1585 MW, of which 56 are operational (REPD Q1 2026).

Questions about solar in Warminster
- What would a 500 kWp array produce on a farm near Warminster?
- Yes, and the figure matters more than the sunshine. At 912 kWh per kWp a year, a 500 kWp array on a Warminster holding models at around 456,000 kWh. What changes the answer is how much of that the farm uses itself. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection around Warminster?
- Applications go to Scottish and Southern Electricity Networks, who run the network across Wiltshire. On a farm the incoming supply matters as much as their answer: a single phase supply caps what can be installed whatever the roof would take.
- What does Wiltshire require for solar on an agricultural building?
- Roof-mounted panels on an agricultural building often fall under permitted development, subject to limits on projection above the roof plane and to the building not being listed or in a conservation area or National Park. We confirm the position with Wiltshire before the design is finalised.
- Has anyone near BA12 already done this?
- The planning database records 4 ground mounted and 1 roof mounted solar schemes in this postcode district. That matters less as proof it works and more as evidence of how the local network has treated export applications. Roof arrays under a megawatt often never appear in the database, so the real figure is higher. Source: Renewable Energy Planning Database, Q1 2026.
