What would a 500 kWp array produce in Kingston?

Yes, and the number matters more than the sunshine. At 987 kWh per kWp a year, a 500 kWp array on a Kingston roof models at around 494,000 kWh. What changes the answer is how much of that you use on site rather than export. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Which network operator handles the connection in Kingston?

Applications go to UK Power Networks, who run the network across Greater London. They decide the export limit, and we handle the G99 paperwork alongside the array design.

Solar panels for warehouses in Kingston

Sheds around Kingston 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 Kingston actually generates

Modelled irradiation at this latitude is 1265 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 987 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 11 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.

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

Jun produces 6.1 times what Dec does on the same roof. A 500 kWp array here models at about 494,000 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.

Kingston ranks 1 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 operates the distribution network across Greater London, 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.
