Solar panels for farms in Swindon
The case for solar on a Swindon holding turns on how much of the output the farm uses itself, not on how much the roof makes. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.
899 kWh per kWp a year at this latitude, so a 500 kWp array models at about 450,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Farm building solar PV across Wiltshire
What a farm roof near Swindon generates
Modelled irradiation at this latitude is 1151 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 899 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.
The planning record lists 1 ground mounted solar scheme 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 2.5 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 Swindon is higher than the record shows.
We survey holdings across the SN postcode area, starting from SN2.
Swindon 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.
Swindon ranks 7 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 Swindon 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 Swindon
- Is there enough sun around Swindon to make this work?
- Modelled at 899 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 450,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export near Swindon?
- Only Scottish and Southern Electricity Networks can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.
- Do we need planning permission in Swindon?
- In most cases no, because panels on the roof of an agricultural building usually sit within permitted development. The exceptions are listed buildings, conservation areas, protected landscapes and arrays that stand proud of the roof. We check with Swindon either way.
- Has anyone near SN2 already done this?
- The planning database records 1 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.
