Solar panels for warehouses in Warminster

What makes a Warminster scheme work is rarely the panels. It is the condition of the roof underneath them. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.

What a roof in Warminster actually 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 towns we cover, which is as good as UK rooftop gets outside the south coast.

Surveys run across BA postcodes, BA12 outward.

Wiltshire is the planning authority for most sites here, and the built-up area holds a population of about 18,020, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

Jul produces 5.7 times what Dec does on the same roof. A 500 kWp array here models at about 456,000 kWh across the year, but it arrives unevenly, which is why we size against your summer daytime load and then look at whether storage is worth adding for the shoulder months.

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.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: location is not the lever, consumption is. Source: EU PVGIS v5.2, modelled per town

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 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 Warminster

What would a 500 kWp array produce in Warminster?
Yes, and the number matters more than the sunshine. At 912 kWh per kWp a year, a 500 kWp array on a Warminster roof models at around 456,000 kWh. What changes the answer is how much of that you use on site rather than export. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Which network operator handles the connection in Warminster?
Applications go to Scottish and Southern Electricity Networks, who run the network across Wiltshire. They decide the export limit, and we handle the G99 paperwork alongside the array design.
What does Wiltshire require for rooftop solar?
Roof-mounted panels on a commercial building usually fall under permitted development, subject to the limits on projection above the roof plane and to the building not being listed or in a conservation area. We confirm the position with Wiltshire before the design is finalised.
Has anyone near BA12 already done this?
The planning database records 5 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.
