Commercial building solar panels across Northamptonshire
We arrange roof surveys on offices, retail units, hotels and leisure buildings throughout Northamptonshire, 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 Northamptonshire
Modelled yield is consistent across Northamptonshire, from 890 kWh per kWp a year at Daventry to 900 at Rushden. At that spread, location does not decide the case. Daytime consumption does.
Across the 2 authorities our Northamptonshire towns sit in, the Valuation Office Agency lists 4,390 office and 4,660 retail properties, 260 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 Corby East Midlands International Pool, Parkland Gateway, Morrisons Supermarket, Lower Street, Belgrave Retail Park, Northfield Avenue and Sainsburys Store And Petrol, Northampton Road. 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.
