Solar panels for warehouses in Dunstable

Most of the industrial stock around Dunstable carries a large, shallow-pitched roof that was never asked to do anything. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.

893 kWh per kWp a year at this latitude, so a 500 kWp array models at about 447,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Dunstable actually generates

Modelled irradiation at this latitude is 1143 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 893 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.

Distribution stock around Dunstable clusters on M1 J11, M1 J11a and A5, which is where the large single-let roofs are.

We survey across the LU postcode area, starting from LU6.

Central Bedfordshire is the planning authority for most sites here, and the built-up area holds a population of about 34,500, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

Jul produces 5.9 times what Dec does on the same roof. A 500 kWp array here models at about 447,000 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.

Dunstable ranks 6 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

From the government's Renewable Energy Planning Database, Q1 2026. These are the schemes on record in this postcode district, which is a fair guide to how the local network has been treating export applications.

Grid connection through UK Power Networks

UK Power Networks is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.

Across Bedfordshire the planning database records 89 solar schemes totalling 837 MW, of which 16 are operational (REPD Q1 2026).

Questions about solar in Dunstable

How much does a warehouse roof in Dunstable generate?
The model gives 893 kWh for every kWp installed here, so 500 kWp comes out at about 447,000 kWh a year before any shading losses. You need roughly 1,485 sqm of clear roof to fit it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Does the grid around Dunstable have capacity?
UK Power Networks is the distribution network operator for Bedfordshire. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. We submit it as part of the design.
Is planning permission needed for panels on a Dunstable unit?
Usually permitted development covers it. We still put the question to Central Bedfordshire before design sign-off, and we tell you early if a full application is needed rather than discovering it late.
Has anyone near LU6 already done this?
The planning database records 2 solar schemes in this postcode district. 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.
