Commercial building solar panels across Greater London
We arrange roof surveys on offices, retail units, hotels and leisure buildings throughout Greater London, model what each roof can carry against the building's own consumption, and arrange the design, the grid application and the install through our MCS-certified partner.

What the data says about Greater London
Modelled yield varies across Greater London: Kingston comes out at 987 kWh per kWp a year against 847 at Sutton. On a 210 kWp commercial roof that gap is about 29,400 kWh a year.
Across the 34 authorities our Greater London towns sit in, the Valuation Office Agency lists 104,480 office and 88,870 retail properties, 1,640 of them large-format stores and retail warehouses.

The planning database records no roof-mounted commercial schemes in the districts we cover in Greater London. That usually means arrays have gone in below its reporting threshold, not that none exist: many commercial roofs carry less than a megawatt and never appear.
Connections across the county run through UK Power Networks. Anything above 3.68 kW per phase needs a G99 application, and the export limit offered shapes the design, so the question is asked before the array is sized.
