Solar panels for farms in Lydney

Farm buildings around Lydney 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.

905 kWh per kWp a year at this latitude, so a 500 kWp array models at about 453,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Lydney generates

Modelled irradiation at this latitude is 1162 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 905 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.

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.

Jul produces 6.4 times what Dec does on the same roof. A 500 kWp array here models at about 453,000 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.

Lydney ranks 1 of 6 towns we cover in Gloucestershire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 870 to 905, a spread of 35 kWh per kWp. Within Gloucestershire 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 Gloucestershire the planning database records 207 solar schemes totalling 1592 MW, of which 39 are operational (REPD Q1 2026).

Questions about solar in Lydney

How much does a farm roof near Lydney generate?
The model gives 905 kWh for every kWp installed here, so 500 kWp comes out at about 453,000 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 Lydney take the export?
National Grid Electricity Distribution is the distribution network operator for Gloucestershire. 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.
