Solar panels for warehouses in Marlborough
Most of the industrial stock around Marlborough carries a large, shallow-pitched roof that was never asked to do anything. The survey measures the roof, not the postcode: cladding profile, purlin centres, remaining sheet life and the load the frame can take.
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.

What a roof in Marlborough actually 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 towns we cover, so the case rests on your consumption pattern rather than on the weather.
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 in 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 walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export in Marlborough?
- Capacity varies street by street, and only Scottish and Southern Electricity Networks can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
