How much does a farm roof near 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 shading losses. A building of roughly 1,485 sqm of clear roof carries it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Is planning permission needed for panels on a farm building near Worthing?

Usually permitted development covers a roof array. Ground mounted arrays are a different question and are far more likely to need a full application. We put both to Worthing before design sign-off.

Solar panels for farms in Worthing

A Worthing farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.

999 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 farm roof near Worthing 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 areas we cover, which is as strong as UK farm rooftop gets outside the south coast.

1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Worthing is higher than the record shows.

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

Worthing is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.

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.

Worthing ranks 6 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.
