How much does a warehouse roof in Worthing generate?

The model gives 999 kWh for every kWp installed here, so 500 kWp comes out at about 500,000 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.

Is planning permission needed for panels on a Worthing unit?

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

Solar panels for warehouses in Worthing

Most of the industrial stock around Worthing 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.

What a roof in Worthing actually generates

Modelled irradiation at this latitude is 1273 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 999 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 13 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.

We survey across the BN postcode area, starting from BN13.

Worthing is the planning authority for most sites here, and the built-up area holds a population of about 111,620, 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 Worthing roof makes, month by month

Jun produces 6.2 times what Dec does on the same roof. A 500 kWp array here models at about 500,000 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.
