Is there enough sun in Stratford to make this work?

Modelled at 904 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 452,000 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 Stratford?

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.

Solar panels for warehouses in Stratford

Sheds around Stratford tend to have more roof than the business has any other use for. What decides a scheme here is the state of the covering and the load path, which is why the survey starts on the roof rather than in a spreadsheet.

What a roof in Stratford actually generates

Modelled irradiation at this latitude is 1163 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 904 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.

FIG. 1 What a Stratford roof makes, month by month

Jul produces 5.7 times what Dec does on the same roof. A 500 kWp array here models at about 452,000 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.

Stratford ranks 24 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.

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 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.
