Solar panels for warehouses in Sevenoaks
Roof space is the one asset a Sevenoaks unit already owns and rarely uses. 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.
920 kWh per kWp a year at this latitude, so a 500 kWp array models at about 460,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Kent
What a roof in Sevenoaks actually generates
Modelled irradiation at this latitude is 1181 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 920 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 4 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.
Most of the units we look at here sit in the TN postcode area.
Sevenoaks is the planning authority for most sites here, and the built-up area holds a population of about 26,475, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Sevenoaks ranks 11 of 12 towns we cover in Kent on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 915 to 990, a spread of 75 kWh per kWp. On a 500 kWp array that is about 37,500 kWh a year between the strongest and weakest town in the county.
Grid connection through UK Power Networks
Connections around Sevenoaks 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.
Across Kent the planning database records 237 solar schemes totalling 2072 MW, of which 45 are operational (REPD Q1 2026).

Questions about solar in Sevenoaks
- What would a 500 kWp array produce in Sevenoaks?
- Yes, and the number matters more than the sunshine. At 920 kWh per kWp a year, a 500 kWp array on a Sevenoaks roof models at around 460,000 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 Sevenoaks?
- Applications go to UK Power Networks, who run the network across Kent. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Sevenoaks require for rooftop solar?
- Roof-mounted panels on a commercial building usually fall under permitted development, subject to the limits on projection above the roof plane and to the building not being listed or in a conservation area. We confirm the position with Sevenoaks before the design is finalised.
