Commercial building solar panels across Dorset
We arrange roof surveys on offices, retail units, hotels and leisure buildings throughout Dorset, 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 Dorset
Modelled yield varies across Dorset: Weymouth comes out at 1006 kWh per kWp a year against 924 at Sherborne. On a 210 kWp commercial roof that gap is about 17,220 kWh a year.
Across the 2 authorities our Dorset towns sit in, the Valuation Office Agency lists 4,150 office and 7,240 retail properties, 240 of them large-format stores and retail warehouses.

The planning database records 4 roof-mounted solar schemes on commercial buildings in the postcode districts we cover here, including Morrisons Supermarket, Dorchester Road and Seaview Holiday Park,Preston Road. These are other organisations' projects, listed from the public record. Source: Renewable Energy Planning Database, Q1 2026.
Connections across the county run through Scottish and Southern Electricity Networks. 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.
