Solar panels for warehouses in Bexley
Roof space is the one asset a Bexley unit already owns and rarely uses. We start with the covering and the structure, because a roof with five years left in it changes the answer entirely.
916 kWh per kWp a year at this latitude, so a 500 kWp array models at about 458,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Greater London
What a roof in Bexley actually generates
Modelled irradiation at this latitude is 1177 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 916 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 3 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.
Bexley ranks 3 of 50 towns we cover in Greater London on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 847 to 987, a spread of 140 kWh per kWp. On a 500 kWp array that is about 70,000 kWh a year between the strongest and weakest town in the county.
Grid connection through UK Power Networks
Connections around Bexley 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.

Questions about solar in Bexley
- How much does a warehouse roof in Bexley generate?
- The model gives 916 kWh for every kWp installed here, so 500 kWp comes out at about 458,000 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 Bexley have capacity?
- UK Power Networks is the distribution network operator for Greater London. 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.
