How much would solar on a commercial building in West Bromwich generate?

The model gives 852 kWh for every kWp installed here, so 210 kWp is about 179,000 kWh a year before shading losses. Allow roughly 1,390 m² of roof for it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Do we need planning permission for solar on a commercial building in Sandwell?

Usually not a full application. In England, panels on the roof of a non-domestic building are permitted development under Class J of Part 14 of the General Permitted Development Order, with no capacity cap since December 2023. Above 50 kW, which covers most commercial arrays, you must first apply to Sandwell for a determination on prior approval of the design and appearance, in particular glare on neighbouring land. On a flat roof panels may stand no more than 1 metre above the roof and must sit at least 1 metre from its edge, and listed buildings and scheduled monuments are excluded. See our planning permission guide for the detail.

Does solar help a West Bromwich landlord meet MEES?

It can. A non-domestic EPC is an asset rating, and on-site generation counts in the calculation, so an array usually lifts the score. Let property in England and Wales must be EPC E or better today. The government's interim response of 18 June 2026 proposes EPC B, where cost effective, from 2031 for let buildings over 1,000 m², and drops the EPC C step once planned for 2027. How far solar moves a particular building depends on its fabric and services, which is why the EPC assessor models it before anything is fitted.

Which network operator handles the connection in West Bromwich?

Capacity varies street by street and only National Grid Electricity Distribution can answer it for your connection. We ask early, because an export-limited offer changes the design rather than ending the scheme, and most commercial buildings use most of what they generate anyway.

Commercial building solar panels in West Bromwich

Commercial roofs in West Bromwich tend to be flat, membrane covered and cluttered with plant, which shapes the layout more than the size does. We check the covering and the lease together, because a roof with eight years of membrane left and a tenant with a break in three changes the answer.

852 kWh per kWp a year at this latitude, so a 210 kWp array models at about 179,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Commercial rooftop solar across West Midlands

Yield on a West Bromwich commercial roof

Modelled irradiation here is 1,091 kWh per square metre a year on a low-tilt array, which works out at 852 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 rests more on daytime consumption than on raw generation.

How many commercial buildings Sandwell has

On the Valuation Office Agency's count, Sandwell holds 2,940 retail and 1,000 office properties on the rating list. By office stock the district sits above the median of the 318 districts in England and Wales; by retail stock it sits in the top quarter of the 318 districts in England and Wales.

The big roofs are in the 100 large-format retail units, superstores and retail warehouses in the district, about 209,000 square metres of floorspace under largely single storey roofs.

The same list carries 360 hotel, leisure and assembly properties in the district. Leisure centres and hotels run seven days a week, which puts weekend generation to use that an office would export.

FIG. 1 What a West Bromwich roof makes, month by month

Jul produces 6.0 times what Dec does on the same roof. A 210 kWp array here models at about 179,000 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.

West Bromwich ranks 4 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).
