Solar panels for farms in Folkestone
Around Folkestone the constraint is rarely the roof. It is the incoming supply and what the network will accept back. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.
990 kWh per kWp a year at this latitude, so a 500 kWp array models at about 495,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Farm building solar PV across Kent
What a farm roof near Folkestone generates
Modelled irradiation at this latitude is 1248 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 990 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 12 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.
No solar scheme is recorded in this postcode district in the planning database. On a farm that usually means nothing has been built above the reporting threshold rather than that nothing has been built, because a roof array on a shed rarely appears in it.
We survey holdings across the CT postcode area, starting from CT20.
Folkestone and Hythe 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.
Folkestone ranks 2 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
UK Power Networks operates the distribution network across Kent, 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.
Across Kent the planning database records 237 solar schemes totalling 2072 MW, of which 45 are operational (REPD Q1 2026).

Questions about solar in Folkestone
- How much does a farm roof near Folkestone generate?
- The model gives 990 kWh for every kWp installed here, so 500 kWp comes out at about 495,000 kWh a year before shading losses. A building of roughly 1,485 sqm of clear roof carries it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Will the rural network around Folkestone take the export?
- UK Power Networks is the distribution network operator for Kent. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. Rural supplies are often the binding constraint, so we ask the question before an array is sized.
- Is planning permission needed for panels on a farm building near Folkestone?
- Usually permitted development covers a roof array. Ground mounted arrays are a different question and are far more likely to need a full application. We put both to Folkestone and Hythe before design sign-off.
