Solar panels for warehouses in Swindon
Most of the industrial stock around Swindon carries a large, shallow-pitched roof that was never asked to do anything. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
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.

What a roof in Swindon actually 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 towns we cover, so the case rests on your consumption pattern rather than on the weather.
Distribution stock around Swindon clusters on M4 J15, M4 J16 and A419, which is where the large single-let roofs are.
We survey across the SN postcode area, starting from SN2.
Swindon is the planning authority for most sites here, and the built-up area holds a population of about 183,680, the size that tends to be served by mid-box last-mile units rather than national hubs (ONS Census 2021 built-up areas).
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 warehouse 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 in 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 walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export in Swindon?
- Capacity varies street by street, and only Scottish and Southern Electricity Networks can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
- Do we need planning permission in Swindon?
- In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with Swindon first either way.
- Has anyone near SN2 already done this?
- The planning database records 2 solar schemes in this postcode district, 1 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
