How much does a farm roof near Wisbech generate?

The model gives 905 kWh for every kWp installed here, so 500 kWp comes out at about 453,000 kWh a year before shading losses. A building of roughly 1,485 sqm of clear roof carries it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Will the rural network around Wisbech take the export?

UK Power Networks is the distribution network operator for Cambridgeshire. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. Rural supplies are often the binding constraint, so we ask the question before an array is sized.

Is planning permission needed for panels on a farm building near Wisbech?

Usually permitted development covers a roof array. Ground mounted arrays are a different question and are far more likely to need a full application. We put both to Fenland before design sign-off.

Has anyone near PE13 already done this?

The planning database records 4 ground mounted and 1 roof mounted solar schemes in this postcode district. That matters less as proof it works and more as evidence of how the local network has treated export applications. Roof arrays under a megawatt often never appear in the database, so the real figure is higher. Source: Renewable Energy Planning Database, Q1 2026.

Solar panels for farms in Wisbech

Around Wisbech the constraint is rarely the roof. It is the incoming supply and what the network will accept back. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.

905 kWh per kWp a year at this latitude, so a 500 kWp array models at about 453,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Wisbech generates

Modelled irradiation at this latitude is 1159 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 905 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.

The planning record lists 4 ground mounted solar schemes in this postcode district, which is a fair guide to how the local network has treated field arrays. The typical consented scheme in this district is about 24.9 MW, with the largest at 49.9 MW. Source: Renewable Energy Planning Database, Q1 2026.

1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Wisbech is higher than the record shows.

We survey holdings across the PE postcode area, starting from PE13.

Fenland is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.

FIG. 1 What a Wisbech 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 453,000 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 farm 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).
