Commercial building solar panels across Devon
We arrange roof surveys on offices, retail units, hotels and leisure buildings throughout Devon, 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 Devon
Modelled yield varies across Devon: Paignton comes out at 961 kWh per kWp a year against 903 at Tiverton. On a 210 kWp commercial roof that gap is about 12,180 kWh a year.
Across the 7 authorities our Devon towns sit in, the Valuation Office Agency lists 5,770 office and 8,780 retail properties, 370 of them large-format stores and retail warehouses.

The planning database records 7 roof-mounted solar schemes on commercial buildings in the postcode districts we cover here, including Sainsburys Supermarket, Plymouth Road, Torbay Leisure Centre - Energy Project, Morrisons, Totnes Road and Devon Cliffs Holiday Centre, Sandy Bay. These are other organisations' projects, listed from the public record. Source: Renewable Energy Planning Database, Q1 2026.
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.
