Is there enough sun in 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 walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Who do we apply to for export in Biggleswade?

Capacity varies street by street, and only UK Power Networks can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.

Do we need planning permission in Central Bedfordshire?

In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with Central Bedfordshire first either way.

Has anyone near SG18 already done this?

The planning database records 6 solar schemes in this postcode district, 5 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.

Solar panels for warehouses in Biggleswade

The economics of a Biggleswade rooftop array turn on how much of the generation the occupier uses on site. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.

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.

What a roof in Biggleswade actually 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 towns we cover, so the case rests on your consumption pattern rather than on the weather.

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

Central Bedfordshire is the planning authority for most sites here, and the built-up area holds a population of about 21,950, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

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 warehouse 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).
