Solar panels for farms in Glastonbury
Farm buildings around Glastonbury carry broad, shallow roofs that were put up for storage and stock, not for generation. 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.
913 kWh per kWp a year at this latitude, so a 500 kWp array models at about 457,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Farm building solar PV across Somerset
What a farm roof near Glastonbury generates
Modelled irradiation at this latitude is 1169 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 913 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 3 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.
Glastonbury ranks 4 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.
Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across Somerset, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.
Across Somerset the planning database records 223 solar schemes totalling 1574 MW, of which 79 are operational (REPD Q1 2026).

Questions about solar in Glastonbury
- How much does a farm roof near Glastonbury generate?
- The model gives 913 kWh for every kWp installed here, so 500 kWp comes out at about 457,000 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 Glastonbury 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.
