Commercial solar in Manchester
Commercial solar PV, battery storage and EV charging for Greater Manchester businesses, designed, installed and maintained by our own team.
Cornerstone Group designs and installs commercial solar PV for warehouses, factories, offices, schools and retail sites across Greater Manchester: Manchester, Salford, Trafford, Stockport, Tameside, Oldham, Rochdale, Bury, Bolton and Wigan. We are based around 30 miles away in Preston and use our own installers and electricians.
Manchester’s industrial estates are full of large, simple roofs with steady daytime electricity use, which is exactly where solar performs best. A well-matched system typically pays for itself in two to four years and then generates low-cost power for decades.
Because roofing is part of the same group, we can replace a tired roof and install the array in one programme. When we fit the roof and install the solar, both are covered by a single combined 30-year warranty.
What’s included
Sized to how you use power
We start with your half-hourly electricity data and roof survey, then size the array so you use as much of the generation on site as possible. Adding battery storage lets you keep surplus power for the evening peak.
The grid connection, handled
Larger systems need approval from the local network operator before they can be switched on. In Greater Manchester that is Electricity North West. We prepare and submit the application and build the lead time into your programme.
Roof first, then solar
Panels last 25 years or more, so the roof beneath must last too. At Booker Watford we replaced the roof and installed 334 kWp of solar together, for a 3.1-year payback. Read should you re-roof before installing solar?

Manchester solar questions answered.
Can't see your question here? Our team is happy to talk it through.
Do you install commercial solar across Greater Manchester?
Yes, in all ten boroughs: Manchester, Salford, Trafford, Stockport, Tameside, Oldham, Rochdale, Bury, Bolton and Wigan. We are based in Preston, around 30 miles from central Manchester, and use our own installers.
How long does commercial solar take to pay back?
Most commercial systems we model pay back in two to four years on a capital purchase, depending on your daytime demand, roof and tariff. We model your site before you commit.
Who deals with the grid connection?
We do. Greater Manchester is covered by Electricity North West, and larger systems need its approval before switch-on. We prepare and submit the application for you.
What if our roof is old?
We survey it first. If it needs replacing, our roofing team can do that and the solar in one programme, with both covered by a single combined 30-year warranty.
Can you add battery storage and EV charging?
Yes. Batteries store surplus solar for peak times, and workplace or fleet EV chargers can run on your own generation. We design them as one system.
