How much does a farm roof near Haywards Heath generate?

The model gives 957 kWh for every kWp installed here, so 500 kWp comes out at about 479,000 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 Haywards Heath?

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 Lewes before design sign-off.

Solar panels for farms in Haywards Heath

Most holdings around Haywards Heath already own the best generating site they will ever have, and it is the roof of the shed they built for something else. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.

957 kWh per kWp a year at this latitude, so a 500 kWp array models at about 479,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Haywards Heath generates

Modelled irradiation at this latitude is 1230 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 957 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 8 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.

No solar scheme is recorded in this postcode district in the planning database. On a farm that usually means nothing has been built above the reporting threshold rather than that nothing has been built, because a roof array on a shed rarely appears in it.

Surveys run across RH postcodes, RH16 outward.

Lewes 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 Haywards Heath 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 479,000 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.

Haywards Heath ranks 8 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.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: location is not the lever, consumption is. Source: EU PVGIS v5.2, modelled per town
