Commercial building solar panels in Tamworth
Most commercial roofs around Tamworth already carry plant, a parapet and an access hatch, and the space between them is where the array goes. Each survey records the usable area once edge strips, plant and walkways are taken out, the load the deck can take, and whether the lease lets the occupier alter the roof.
857 kWh per kWp a year at this latitude, so a 210 kWp array models at about 180,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Commercial rooftop solar across Staffordshire
Yield on a Tamworth commercial roof
Modelled irradiation here is 1,098 kWh per square metre a year on a low-tilt array, which works out at 857 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 3 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 Tamworth has
On the Valuation Office Agency's count, Tamworth holds 510 retail and 420 office properties on the rating list. By office stock the district sits in the bottom quarter of the 318 districts in England and Wales; by retail stock it sits in the bottom quarter of the 318 districts in England and Wales.
50 of those retail properties are superstores, large food stores, large shops or retail warehouses, together about 70,000 square metres. Single storey boxes of that size are where most commercial rooftop solar actually gets built, because the roof is big, flat or shallow, and uninterrupted.
The same list carries 70 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.

Commercial rooftop solar already planned near Tamworth
The Renewable Energy Planning Database records one roof-mounted scheme on supermarket and retail buildings in this postcode district. These are other organisations' projects, listed from the public record, not ours.
| Scheme | Applicant | Type | Capacity | Status |
|---|---|---|---|---|
| Marlborough Way, Belgrave | WM Morrisons Supermarkets Plc | retail | 0.33 MW | Awaiting Construction |
The built-up area holds about 76,090 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).

Tamworth ranks 1 of 7 towns we cover in Staffordshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 826 to 857, a spread of 31 kWh per kWp. Within Staffordshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Staffordshire the planning database records 118 solar schemes totalling 1054 MW, of which 17 are operational (REPD Q1 2026).

Questions about solar in Tamworth
- How much would solar on a commercial building in Tamworth generate?
- The model gives 857 kWh for every kWp installed here, so 210 kWp is about 180,000 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.
- Is planning permission needed for panels on a Tamworth office or shop?
- 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 Tamworth 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.
- Will rooftop solar improve the EPC rating of a let building in Tamworth?
- 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.
- Does the grid around Tamworth have capacity for export?
- National Grid Electricity Distribution is the distribution network operator for Staffordshire. Arrays above 3.68 kW per phase connect under G99, and the application sets the export limit. It is part of the design work we arrange.
