Solar panels for warehouses in Dartford
What makes a Dartford scheme work is rarely the panels. It is the condition of the roof underneath them. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
915 kWh per kWp a year at this latitude, so a 500 kWp array models at about 458,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Dartford actually generates
Modelled irradiation at this latitude is 1175 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 915 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 3 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.
Distribution stock around Dartford clusters on M25 J1a, A2 and A282, which is where the large single-let roofs are.
Surveys run across DA postcodes, DA2 outward.
Dartford is the planning authority for most sites here, and the built-up area holds a population of about 69,130, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
Dartford ranks 12 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.

| Scheme | Operator | Capacity | Mounting | Status |

| Riverbridge House, Admirals Park - Solar Panels | PCP IV Alpha Limited | 0.27 MW | Roof | Awaiting Construction |
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 Dartford
- Is there enough sun in Dartford to make this work?
- Modelled at 915 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 458,000 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 Dartford?
- 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 Dartford?
- 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 Dartford first either way.
- Has anyone near DA2 already done this?
- The planning database records 2 solar schemes in this postcode district, 2 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
