Is there enough sun in Bognor Regis to make this work?

Modelled at 1000 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 500,000 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.

Do we need planning permission in Arun?

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 Arun first either way.

Solar panels for warehouses in Bognor Regis

What makes a Bognor Regis scheme work is rarely the panels. It is the condition of the roof underneath them. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.

1000 kWh per kWp a year at this latitude, so a 500 kWp array models at about 500,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Bognor Regis actually generates

Modelled irradiation at this latitude is 1267 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 1000 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.

Surveys run across PO postcodes, PO21 outward.

Arun is the planning authority for most sites here, and the built-up area holds a population of about 68,435, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

FIG. 1 What a Bognor Regis 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.

Bognor Regis ranks 5 of 10 towns we cover in Sussex on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 915 to 1028, a spread of 113 kWh per kWp. On a 500 kWp array that is about 56,500 kWh a year between the strongest and weakest town in the county.
