Is there enough sun in Hastings to make this work?

Modelled at 989 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 495,000 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 Hastings?

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 Hastings first either way.

Sheds around Hastings 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 Hastings actually generates

Modelled irradiation at this latitude is 1272 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 989 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 12 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 TN postcode area, starting from TN34.

Hastings is the planning authority for most sites here, and the built-up area holds a population of about 91,490, 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 Hastings roof makes, month by month

Jun produces 6.1 times what Dec does on the same roof. A 500 kWp array here models at about 495,000 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.

Hastings ranks 7 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.
