Solar panels for warehouses in Gravesend

Sheds around Gravesend tend to have more roof than the business has any other use for. 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.

What a roof in Gravesend actually generates

Modelled irradiation at this latitude is 1189 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 926 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 5 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.

Distribution stock around Gravesend clusters on A2 and M25 J2, which is where the large single-let roofs are.

We survey across the DA postcode area, starting from DA12.

Gravesham is the planning authority for most sites here, and the built-up area holds a population of about 58,105, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

Jul produces 5.9 times what Dec does on the same roof. A 500 kWp array here models at about 463,000 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.

Gravesend ranks 9 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).

Solar already consented near DA12

From the government's Renewable Energy Planning Database, Q1 2026. These are the schemes on record in this postcode district, which is a fair guide to how the local network has been treating export applications.

Questions about solar in Gravesend

Is there enough sun in Gravesend to make this work?
Modelled at 926 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 463,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Who do we apply to for export in Gravesend?
Capacity varies street by street, and only UK Power Networks can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
Do we need planning permission in Gravesham?
In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with Gravesham first either way.
