Commercial building solar panels in Cannock
Commercial roofs in Cannock tend to be flat, membrane covered and cluttered with plant, which shapes the layout more than the size does. What decides a scheme is the roof covering, the parapet height and the plant layout, which is why the survey happens on the roof rather than from a satellite image.

Commercial rooftop solar across Staffordshire
Yield on a Cannock commercial roof
Modelled irradiation here is 1,078 kWh per square metre a year on a low-tilt array, which works out at 842 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 5 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 Cannock Chase has
On the Valuation Office Agency's count, Cannock Chase holds 1,000 retail and 600 office properties on the rating list. By office stock the district sits below the median of the 318 districts in England and Wales; by retail stock it sits below the median of the 318 districts in England and Wales.
The big roofs are in the 80 large-format retail units, superstores and retail warehouses in the district, about 109,000 square metres of floorspace under largely single storey roofs.
The same list carries 140 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.

The built-up area holds about 63,065 people, so the stock here runs to high street premises, a supermarket or two and the odd hotel (ONS Census 2021 built-up areas).
We arrange surveys across the WS postcode area, starting from WS11.
Cannock ranks 5 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 operates the distribution network across Staffordshire, 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 Staffordshire the planning database records 118 solar schemes totalling 1054 MW, of which 17 are operational (REPD Q1 2026).

Questions about solar in Cannock
- How much would solar on a commercial building in Cannock generate?
- The model gives 842 kWh for every kWp installed here, so 210 kWp is about 177,000 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 Cannock Chase?
- 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 Cannock Chase 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 Cannock 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 Cannock?
- 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.
