The case for solar · Warehouses & logistics

Cut your warehouse power bill by up to 70% Solar panels for warehouses and logistics, built as a business case.

*Dependent on the customer’s consumption, generation and electricity cost at the time of install.

A warehouse has the biggest, flattest, emptiest roof in your estate, and a load that runs long hours: high-bay lighting, racking, chargers, chillers. Point solar at it and that roof becomes a generating asset. One Greenford distribution site now runs more than 40% of its power off its own roof, and is on track to save a quarter of a million pounds over the system's life.

01
The opportunity

The biggest roof in your estate is doing nothing

Solar panels for warehouses make sense because warehouses and distribution sheds have the largest unbroken roofs in British business, and most of them sit empty. Meanwhile the building draws power for long hours, often around the clock: high-bay lighting, conveyors, racking, and it is that steady draw that makes solar panels for warehouses pay. Add battery charging, and increasingly refrigeration and EV fleets. That combination, a huge roof over a long, steady load, is the single best case for solar there is. You generate on the roof and use it on the floor, so very little is ever wasted back to the grid.

Warehouses also carry a big slice of fixed grid charges tied to peak demand. Solar shaves that peak, so you save on the units and on the standing charges. And as fleets electrify, a warehouse roof can feed the chargers directly, turning daytime sun into fuel for your vans and HGVs instead of buying it at grid or forecourt rates. It works whether you call it a warehouse, a distribution centre, a logistics hub or an industrial unit.

02
The business case

It reads straight on a logistics P&L

Energy is one of the few warehouse costs you can actually attack. Warehouse solar converts a rising, volatile bill into a fixed asset with a payback a finance director can sign off. The same rooftop solar PV is clean, sustainable energy that cuts your environmental impact as much as your bills. Qualifying commercial solar can be written down against tax under current capital-allowance rules, which shortens payback, and grant support exists for some sites. For 3PLs and landlords it also lifts the asset: a greener building lets, leases and sells better, and answers the carbon questions now built into most logistics tenders, from ISO 14001 and CHAS to a customer's own net-zero targets. On-site solar is clean energy that lifts your sustainability rating.

There is a resilience dividend too. A site making its own power is less exposed when wholesale prices spike, and pairing panels with battery storage keeps critical load, chillers, security and comms, steadier through a grid event. On a warehouse, where a few hours of downtime can strand a whole day's dispatch, that matters more than most.

The key benefits of installing solar panels for warehouses

Put the biggest roof to work
A warehouse roof is thousands of square metres of unused space. Turn it into renewable energy that cuts your energy bills, operating costs and grid electricity.
Slash long-hours energy costs
Lighting, racking, chillers and chargers run for hours. Cover them with power you make, not power you buy.
Fuel your EV fleet
EV charging runs vans and HGVs off your own roof, turning daytime solar energy into clean fleet fuel instead of grid or forecourt rates.
Lift the asset value
A greener, more sustainable building lets, leases and sells better, and its lower carbon footprint and carbon emissions answer the net zero questions in every logistics tender.
Low maintenance, long life
Panels have no moving parts, sit out of the way on the roof, and are covered by a 25-year warranty.
Strong, stable ROI
Big roof, steady load: warehouses see some of the best payback in commercial solar, often five to six years.

The numbers, from a real distribution warehouse

We don't deal in vague promises. Here is exactly what solar did on a Greenford distribution site, the kind of numbers we will model for your warehouse before you commit to anything.

The bottom line

A flat roof that used to sit empty now covers more than 40% of a Greenford distribution site's power, and is on track to pay back £240,000 to £260,000 over its life. We put those numbers in front of them before they signed, not after.

How it works

Installed around your operation, not through it

A commercial solar installation on a working warehouse is a different job from a home system. One team, in-house, from first site visit to switch-on, and we plan the work around your shifts so dispatch keeps running.

STEP 01
Site visit
We assess your roof, structure, load profile and half-hourly usage on site.
STEP 02
Design and projection
You get a system sized to your roof and a real projection of cost, savings and payback.
STEP 03
Grid and paperwork
We handle the DNO application and every certificate, so you don't have to chase it.
STEP 04
Install, zero downtime
our MCS-registered installers fit it around your shifts. Production keeps running.
STEP 05
Switch-on and aftercare
Commissioning, monitoring and a team you can call. We don't disappear after handover.

Good to know

The questions warehouse and logistics operators actually ask before committing to commercial solar.

Will my warehouse roof take the weight?

Most large-span warehouse and distribution roofs are built for it, but we never assume. Every job starts with a structural check as part of the site visit, and we design the mounting to suit your roof, whether it is trapezoidal steel, standing seam, built-up felt or a flat membrane. If it needs strengthening, we tell you up front, before anything is ordered.

Will the installation disrupt operations or dispatch?

It doesn't have to. Almost all of the work happens on the roof, away from the floor, racking and loading bays. We plan around your shifts, deliveries and dispatch windows, isolate only what we must and only when agreed, and keep the site running. Zero operational downtime is the target we plan to hit.

How much does a warehouse solar system cost?

Every roof and load is different, so we size and price it to your site and how you use power, then show you what it gives back. A Greenford distribution site's 51.6 kWp system cost £54,000 and is on track to save £240,000 to £260,000 over its life. You get the same honest projection first.

What payback can a warehouse expect?

Because a warehouse pairs a huge roof with a long, steady daytime load, the return is usually strong, often five to six years, then decades of generation under a 25-year panel warranty. We model your exact figures so you can take a real number to your board.

Can it charge our EV fleet or work with batteries?

Yes. A warehouse roof is ideal for feeding on-site chargers, turning daytime generation into fleet fuel, and pairing panels with battery storage lets you shift solar into the evening and hold critical load through a grid event. We design it around how your fleet and shifts actually run.

Do you handle the DNO and grid application?

Yes. A larger warehouse system needs approval from your Distribution Network Operator, and we manage that application for you along with all certification, so you get a signed-off, compliant system without project-managing the grid paperwork yourself.
