Is there enough sun in Sandy 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 Sandy?

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 SG19 already done this?

The planning database records 5 solar schemes in this postcode district, 1 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 Sandy

A Sandy warehouse roof sits idle through exactly the hours its occupier buys the most expensive electricity. We start with the covering and the structure, because a roof with five years left in it changes the answer entirely.

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 Sandy actually generates

Modelled irradiation at this latitude is 1155 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.

Surveys run across SG postcodes, SG19 outward.

Central Bedfordshire is the planning authority for most sites here, and the built-up area holds a population of about 11,375, 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 Sandy roof makes, month by month

Jun produces 5.9 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.

Sandy ranks 2 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

UK Power Networks operates the distribution network across Bedfordshire, 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 Bedfordshire the planning database records 89 solar schemes totalling 837 MW, of which 16 are operational (REPD Q1 2026).
