Is there enough sun around Biggleswade to make this work?

Modelled at 902 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 451,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Who do we apply to for export near Biggleswade?

Only UK Power Networks can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.

Do we need planning permission in Central Bedfordshire?

In most cases no, because panels on the roof of an agricultural building usually sit within permitted development. The exceptions are listed buildings, conservation areas, protected landscapes and arrays that stand proud of the roof. We check with Central Bedfordshire either way.

Has anyone near SG18 already done this?

The planning database records 1 ground mounted and 5 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 Biggleswade

A Biggleswade farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.

902 kWh per kWp a year at this latitude, so a 500 kWp array models at about 451,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Agricultural rooftop solar across Bedfordshire

What a farm roof near Biggleswade generates

Modelled irradiation at this latitude is 1154 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 902 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 1 ground mounted solar scheme 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 13 MW. Source: Renewable Energy Planning Database, Q1 2026.

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

Most of the buildings we look at here sit in the SG postcode area.

Central Bedfordshire 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 Biggleswade roof makes, month by month

Jun produces 5.6 times what Dec does on the same roof. A 500 kWp array here models at about 451,000 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.

Biggleswade ranks 1 of 7 towns we cover in Bedfordshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 892 to 902, a spread of 10 kWh per kWp. Within Bedfordshire 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 Biggleswade 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 Bedfordshire the planning database records 89 solar schemes totalling 837 MW, of which 16 are operational (REPD Q1 2026).
