How much would solar on a commercial building in Wisbech generate?

The model gives 905 kWh for every kWp installed here, so 210 kWp is about 190,000 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 Fenland?

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 Fenland 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 Wisbech 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 Wisbech?

Capacity varies street by street and only UK Power Networks 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 Wisbech

Commercial roofs in Wisbech 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.

905 kWh per kWp a year at this latitude, so a 210 kWp array models at about 190,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Yield on a Wisbech commercial roof

Modelled irradiation here is 1,159 kWh per square metre a year on a low-tilt array, which works out at 905 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is within a few percent of the mean across the towns we cover, so the weather is not what decides the case here. Opening hours are.

How many commercial buildings Fenland has

On the Valuation Office Agency's count, Fenland holds 780 retail and 400 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.

The big roofs are in the 40 large-format retail units, superstores and retail warehouses in the district, about 42,000 square metres of floorspace under largely single storey roofs.

The same list carries 160 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 26,795 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 PE postcode area, starting from PE13.

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

Jul produces 5.9 times what Dec does on the same roof. A 210 kWp array here models at about 190,000 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.

Wisbech ranks 4 of 8 towns we cover in Cambridgeshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 898 to 908, a spread of 10 kWh per kWp. Within Cambridgeshire 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 UK Power Networks

Connections around Wisbech are handled by UK Power Networks, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a commercial building uses most of what the roof makes during the working day.

Across Cambridgeshire the planning database records 172 solar schemes totalling 2422 MW, of which 46 are operational (REPD Q1 2026).
