Solar panels for farms in Marlborough
The case for solar on a Marlborough holding turns on how much of the output the farm uses itself, not on how much the roof makes. 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.
900 kWh per kWp a year at this latitude, so a 500 kWp array models at about 450,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Farm building solar PV across Wiltshire
What a farm roof near Marlborough generates
Modelled irradiation at this latitude is 1152 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 900 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.
Marlborough ranks 6 of 8 towns we cover in Wiltshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 894 to 923, a spread of 29 kWh per kWp. Within Wiltshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Grid connection through Scottish and Southern Electricity Networks
Scottish and Southern Electricity Networks 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 Wiltshire the planning database records 159 solar schemes totalling 1585 MW, of which 56 are operational (REPD Q1 2026).

Questions about solar in Marlborough
- Is there enough sun around Marlborough to make this work?
- Modelled at 900 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 450,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export near Marlborough?
- Only Scottish and Southern Electricity Networks can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.
