How much does a warehouse roof in Salisbury generate?

The model gives 923 kWh for every kWp installed here, so 500 kWp comes out at about 462,000 kWh a year before any shading losses. You need roughly 1,485 sqm of clear roof to fit it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Does the grid around Salisbury have capacity?

Scottish and Southern Electricity Networks is the distribution network operator for Wiltshire. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. We submit it as part of the design.

Is planning permission needed for panels on a Salisbury unit?

Usually permitted development covers it. We still put the question to Wiltshire before design sign-off, and we tell you early if a full application is needed rather than discovering it late.

Has anyone near SP2 already done this?

The planning database records 5 solar schemes in this postcode district, 5 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.

Solar panels for warehouses in Salisbury

Most of the industrial stock around Salisbury carries a large, shallow-pitched roof that was never asked to do anything. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.

923 kWh per kWp a year at this latitude, so a 500 kWp array models at about 462,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Salisbury actually generates

Modelled irradiation at this latitude is 1182 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 923 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 4 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.

We survey across the SP postcode area, starting from SP2.

Wiltshire is the planning authority for most sites here, and the built-up area holds a population of about 47,690, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

FIG. 1 What a Salisbury roof makes, month by month

Jul produces 5.7 times what Dec does on the same roof. A 500 kWp array here models at about 462,000 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.

Salisbury ranks 1 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

Scottish and Southern Electricity Networks operates the distribution network across Wiltshire, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.

Across Wiltshire the planning database records 159 solar schemes totalling 1585 MW, of which 56 are operational (REPD Q1 2026).
