Solar panels for farms in Sevenoaks
The case for solar on a Sevenoaks holding turns on how much of the output the farm uses itself, not on how much the roof makes. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.

Agricultural rooftop solar across Kent
What a farm roof near Sevenoaks 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 areas we cover, which is as strong as UK farm rooftop gets outside the south coast.
1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Sevenoaks is higher than the record shows.
Most of the buildings we look at here sit in the TN postcode area.
Sevenoaks is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.
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 farm 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 on a farm near Sevenoaks?
- Yes, and the figure matters more than the sunshine. At 920 kWh per kWp a year, a 500 kWp array on a Sevenoaks holding models at around 460,000 kWh. What changes the answer is how much of that the farm uses itself. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection around Sevenoaks?
- Applications go to UK Power Networks, who run the network across Kent. On a farm the incoming supply matters as much as their answer: a single phase supply caps what can be installed whatever the roof would take.
- What does Sevenoaks require for solar on an agricultural building?
- Roof-mounted panels on an agricultural building often fall under permitted development, subject to limits on projection above the roof plane and to the building not being listed or in a conservation area or National Park. We confirm the position with Sevenoaks before the design is finalised.
