How much does a farm roof near Weston-super-Mare generate?

The model gives 934 kWh for every kWp installed here, so 500 kWp comes out at about 467,000 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.

Will the rural network around Weston-super-Mare take the export?

National Grid Electricity Distribution is the distribution network operator for Somerset. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. Rural supplies are often the binding constraint, so we ask the question before an array is sized.

Is planning permission needed for panels on a farm building near Weston-super-Mare?

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 North Somerset before design sign-off.

Has anyone near BS23 already done this?

The planning database records 0 ground mounted and 4 roof mounted solar schemes in this postcode district. That matters less as proof it works and more as evidence of how the local network has treated export applications. Roof arrays under a megawatt often never appear in the database, so the real figure is higher. Source: Renewable Energy Planning Database, Q1 2026.

Solar panels for farms in Weston-super-Mare

A Weston-super-Mare farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.

934 kWh per kWp a year at this latitude, so a 500 kWp array models at about 467,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Weston-super-Mare generates

Modelled irradiation at this latitude is 1196 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 934 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 5 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.

4 roof mounted schemes are on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Weston-super-Mare is higher than the record shows.

Surveys run across BS postcodes, BS23 outward.

North Somerset 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 Weston-super-Mare roof makes, month by month

Jul produces 6.1 times what Dec does on the same roof. A 500 kWp array here models at about 467,000 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.

Weston-super-Mare ranks 1 of 8 towns we cover in Somerset on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 894 to 934, a spread of 40 kWh per kWp. Within Somerset that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

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

Grid connection through National Grid Electricity Distribution

National Grid Electricity Distribution is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.

Across Somerset the planning database records 223 solar schemes totalling 1574 MW, of which 79 are operational (REPD Q1 2026).
