Is there enough sun in Walsall to make this work?

Modelled at 851 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 426,000 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 Walsall?

Capacity varies street by street, and only National Grid Electricity Distribution 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 Walsall?

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 Walsall first either way.

Has anyone near WS1 already done this?

The planning database records 4 solar schemes in this postcode district, 4 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 Walsall

What makes a Walsall 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.

851 kWh per kWp a year at this latitude, so a 500 kWp array models at about 426,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Walsall actually generates

Modelled irradiation at this latitude is 1090 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 851 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 4 percent below the mean across the towns we cover, so the case here leans harder on how much you use on site rather than on raw generation.

Distribution stock around Walsall clusters on M6 J7, M6 J9 and M6 J10, which is where the large single-let roofs are.

Surveys run across WS postcodes, WS1 outward.

Walsall is the planning authority for most sites here, and the built-up area holds a population of about 70,775, 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 Walsall roof makes, month by month

Jul produces 5.9 times what Dec does on the same roof. A 500 kWp array here models at about 426,000 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.

Walsall ranks 6 of 8 towns we cover in West Midlands on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 839 to 868, a spread of 29 kWh per kWp. Within West Midlands 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 National Grid Electricity Distribution

National Grid Electricity Distribution operates the distribution network across West Midlands, 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 West Midlands the planning database records 195 solar schemes totalling 533 MW, of which 3 are operational (REPD Q1 2026).
