Commercial building solar panels across Powys
We arrange roof surveys on offices, retail units, hotels and leisure buildings throughout Powys, model what each roof can carry against the building's own consumption, and arrange the design, the grid application and the install through our MCS-certified partner.

What the data says about Powys
Modelled yield is consistent across Powys, from 820 kWh per kWp a year at Newtown to 838 at Hay on Wye. At that spread, location does not decide the case. Daytime consumption does.
Across the authority our Powys towns sit in, the Valuation Office Agency lists 890 office and 1,410 retail properties, 30 of them large-format stores and retail warehouses. Source: Valuation Office Agency, Non-domestic rating: business floorspace, 31 March 2025 (published December 2025), counts and floorspace by special category code and local authority district, England and Wales.
The planning database records no roof-mounted commercial schemes in the districts we cover in Powys. That usually means arrays have gone in below its reporting threshold, not that none exist: many commercial roofs carry less than a megawatt and never appear.
Connections across the county run through National Grid Electricity Distribution. Anything above 3.68 kW per phase needs a G99 application, and the export limit offered shapes the design, so the question is asked before the array is sized.
