Solar panels for warehouses in Ashford

A Ashford warehouse roof sits idle through exactly the hours its occupier buys the most expensive electricity. We start with the covering and the structure, because a roof with five years left in it changes the answer entirely.

What a roof in Ashford actually generates

Modelled irradiation at this latitude is 1256 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 983 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.

Distribution stock around Ashford clusters on M20 J9, M20 J10 and A2070, which is where the large single-let roofs are.

Jun produces 6.0 times what Dec does on the same roof. A 500 kWp array here models at about 492,000 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.

Ashford ranks 3 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.

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 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 Ashford

How much does a warehouse roof in Ashford generate?
The model gives 983 kWh for every kWp installed here, so 500 kWp comes out at about 492,000 kWh a year before any shading losses. You need roughly 1,485 sqm of clear roof to fit it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Does the grid around Ashford have capacity?
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. We submit it as part of the design.
