Commercial building solar panels across Berkshire
We arrange roof surveys on offices, retail units, hotels and leisure buildings throughout Berkshire, 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 Berkshire
Modelled yield is consistent across Berkshire, from 891 kWh per kWp a year at Bracknell to 910 at Thatcham. At that spread, location does not decide the case. Daytime consumption does.
Across the 6 authorities our Berkshire towns sit in, the Valuation Office Agency lists 7,610 office and 5,690 retail properties, 290 of them large-format stores and retail warehouses.

The planning database records 8 roof-mounted solar schemes on commercial buildings in the postcode districts we cover here, including Unit 2a, Slough Retail Park, David Lloyd Royal Berkshire, Car Park Legoland Windsor Resort, Winkfield Road and Waitrose, King Edward Court. 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.
