How much does a warehouse roof in Maidstone generate?

The model gives 930 kWh for every kWp installed here, so 500 kWp comes out at about 465,000 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 Maidstone 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.

Is planning permission needed for panels on a Maidstone unit?

Usually permitted development covers it. We still put the question to Maidstone before design sign-off, and we tell you early if a full application is needed rather than discovering it late.

Has anyone near ME15 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.

Solar panels for warehouses in Maidstone

Most of the industrial stock around Maidstone carries a large, shallow-pitched roof that was never asked to do anything. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.

930 kWh per kWp a year at this latitude, so a 500 kWp array models at about 465,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Maidstone actually generates

Modelled irradiation at this latitude is 1193 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 930 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 Maidstone clusters on M20 J7, M20 J8 and A20, which is where the large single-let roofs are.

We survey across the ME postcode area, starting from ME15.

Maidstone is the planning authority for most sites here, and the built-up area holds a population of about 109,490, the size that tends to be served by mid-box last-mile units rather than national hubs (ONS Census 2021 built-up areas).

FIG. 1 What a Maidstone roof makes, month by month

Jun produces 5.9 times what Dec does on the same roof. A 500 kWp array here models at about 465,000 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.

Maidstone ranks 6 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 is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.

Across Kent the planning database records 237 solar schemes totalling 2072 MW, of which 45 are operational (REPD Q1 2026).
