Commercial building solar panels across Merseyside
We arrange roof surveys on offices, retail units, hotels and leisure buildings throughout Merseyside, 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 Merseyside
Modelled yield varies across Merseyside: Southport comes out at 877 kWh per kWp a year against 830 at St Helens. On a 210 kWp commercial roof that gap is about 9,870 kWh a year.
Across the 4 authorities our Merseyside towns sit in, the Valuation Office Agency lists 8,660 office and 13,440 retail properties, 490 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 Tesco, Bidston Link Road, Bidston, Tesco Pharmacy, Bidston and St Helens Rugby League Stadium, Peasley Cross Lane. These are other organisations' projects, listed from the public record. Source: Renewable Energy Planning Database, Q1 2026.
Connections across the county run through SP Energy 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.
- Liverpool 848 kWh/kWp
- Birkenhead 855 kWh/kWp
- St Helens 830 kWh/kWp
- Southport 877 kWh/kWp
