Solar for warehouses, distribution centres and retail units

If you own a warehouse, distribution centre, retail unit or cash-and-carry building anywhere in Greater Manchester, the chances are you're sitting on a flat roof that could be earning its keep instead of just keeping the rain off.

We're currently designing a system for a carpet and interior design warehouse in Bolton. The family own their building, bought it in the 1980s, and currently spend £700 a month on electricity. Our 50-panel flat-roof design takes that bill to zero with a three-year payback. Or a larger 115-panel system covering both the flat roof and the pitched sections, which still pays back in four years.

After payback, both options deliver decades of free energy plus income from selling excess back to the grid through the Smart Export Guarantee.

Why warehouses are ideal for commercial solar

Warehouses tick every box for a strong return:

• Big roofs, often unused and unobstructed
• Daytime electricity demand - lighting, conveyors, forklifts on charge, climate control - matched to peak solar generation
• Single ownership of the building, which is required to make the payback work
• Long-term occupation - most warehouse owners aren't planning to move
• Flat roof flexibility - we can mount panels to point south regardless of how the building is oriented

Because warehouse and retail operations consume electricity during the day when solar generation is at its peak, you use nearly every kilowatt-hour your panels produce. That's why payback periods on commercial properties are typically 3-4 years - much faster than on a typical home, where most consumption happens in the evening.

Why flat roofs work brilliantly

Flat roofs give us flexibility that pitched roofs don't. We can mount panels pointing south regardless of building orientation, which is why retail units, warehouses and commercial properties with large flat roofs generate substantial energy throughout the day. Many commercial buildings have large flat roof spaces going unused - we can turn those into assets that produce savings for decades.

If you've got pitched roof sections too, those can usually be incorporated into a combined design - the Bolton job is a good example, with options at multiple system sizes.

Ground-mounted and EV-charging additions

If your site has spare land, grass verges or yard space, ground-mounted solar can supplement rooftop generation or power EV charging points for staff and visitor vehicles. We've installed ground-mounted systems connected to outdoor fuse boards for businesses wanting to offer free EV charging to staff - powered entirely by solar, with no recurring electricity cost.

That's a strong staff benefit, an eye-catching environmental statement for visitors and clients, and something your competitors probably aren't doing.

What you need to qualify

The main requirement is that you own the building - solar installations on leased or rented warehouses don't work because you need long-term ownership to realise the payback. You'll also need:

• Sufficient roof space (south-facing pitched, flat of any orientation, or available ground space)
• High enough electricity consumption to give a good return - the more you spend, the faster the payback
• A plan to keep the property long-term to maximise the financial benefits

How the process works

When you get in touch, a qualified electrician (Ashley) assesses your property and reviews your electricity usage. Not a salesperson working from a script. We then put together detailed designs showing projected generation, cost savings, and payback period based on your actual usage data. Most commercial clients get multiple design options - flat roof only, pitched roof only, or combined - with full financial analysis for each.

Installation is coordinated to minimise disruption to your operations. After commissioning, we handle the grid connection requirements, provide electrical certifications and set up your Smart Export Guarantee arrangements.
