Commercial building solar panels across Hampshire
We arrange roof surveys on offices, retail units, hotels and leisure buildings throughout Hampshire, 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 Hampshire
Modelled yield varies across Hampshire: Portsmouth comes out at 987 kWh per kWp a year against 903 at Aldershot. On a 210 kWp commercial roof that gap is about 17,640 kWh a year.
Across the 9 authorities our Hampshire towns sit in, the Valuation Office Agency lists 8,610 office and 8,760 retail properties, 400 of them large-format stores and retail warehouses.

The planning database records 5 roof-mounted solar schemes on commercial buildings in the postcode districts we cover here, including Worting 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.
