Commercial solar in Trowbridge - FAQs

Does MoD supply-chain Scope-3 pressure drive PV here?

Yes - the MoD's Defence Sustainability Strategy audits tier-2 and tier-3 supplier Scope-2 evidence rigorously, especially for Corsham cyber / digital and Boscombe Down test-evaluation feeders. On-site PV is now expected primary evidence.

How does south-west irradiance affect BA14 payback?

Trowbridge sits in the top UK irradiance band (around 1,000–1,050 kWh/kWp/year). Combined with continuous machine-shop and food-manufacturing loads, payback frequently lands in the 4.5–5.5 year range on properly sized arrays.

What array sizes do BA14 industrial estates support?

Bradley Road and the wider West Wiltshire estates typically support 200–800 kWp east-west ballasted arrays on modern units. Airsprung-scale legacy footprints deliver 500 kWp–1 MWp with structural review.

Is SSE Networks grid capacity a constraint in Trowbridge?

The West Wiltshire network retains reasonable 33 kV headroom. Sub-500 kWp G99 with default export limitation clears reliably; multi-MW warrants an early SSEN study but is deliverable across most of BA14.

How wide is West Wiltshire coverage from Trowbridge?

Hilperton, Staverton, Southwick, North Bradley, Westbury-edge, Bradford-on-Avon-edge, Melksham-edge and along the A361 to Devizes and out to Warminster are all routine day-one visits from the Wiltshire team.
