01
The client

An IT business that runs on power, around the clock

CAE Technology Services keeps other businesses running, servers, infrastructure, the systems people rely on without ever thinking about them. That mission takes serious, constant electricity, and it had become one of the biggest running costs the company carried, keeping the racks and the lights on. As that bill climbed, CAE wanted more than a smaller invoice. They wanted predictable costs, and a way to put money back into growth and their mission instead of straight into the grid.

02
The challenge

Money straight out of growth, every year

Every pound going to grid electricity was a pound not going into people, service, or growth. For a company built on efficiency, that was the one line that kept climbing and never worked harder for them. The real question wasn't whether to act, it was how to cut it without disrupting an IT operation that simply can't afford downtime.

03
What we did

A 24.6 kW system, sized to the load

We didn't sell CAE a number off a shelf, we designed a 24.6 kW rooftop system, around 58 panels, matched to how the business actually uses power: heavily, and in daylight. We ran the whole job end to end, from site visit and design through to install and commissioning, and scheduled it around the business so the IT operation never skipped a beat.

  • ~58 panels (24.6 kW total), sized to CAE’s daytime demand
  • Commercial inverter + monitoring
  • Designed to generate in the same daytime hours CAE draws the most power
  • Installed around a live IT operation with zero downtime, future-proofed for battery

The results

A 69% cut, straight off the bill

CAE’s electricity bill fell by close to 69%. The system generates an estimated ~22,000 kWh a year and avoids around 4.5 tonnes of CO₂ annually (both estimated from the 24.6 kW system size and UK yield). Money that used to leave the building now stays in it, in the same daylight hours the business runs hardest. Over the system’s 25-year life that is roughly £92,000 to £123,000, on an install that typically pays for itself in five to six years.

Generation and saving figures on this page are estimates, modelled from the system size and a typical UK yield. They are not meter readings. Your own figures depend on your roof, your usage and the weather in any given year, and we confirm them from a real assessment rather than a model.

Good to know

Common questions about commercial solar, and how they played out for CAE.

Does solar pay off for a business that uses power all day?

That’s exactly where it pays best. CAE draws electricity heavily in daylight hours, the same hours the panels generate, so a large share is used on site the moment it’s made. That’s what took roughly two‑thirds off their bill. We’ll model your exact load and roof and show you the real numbers before you commit.

What does a commercial system like this cost?

Every building is different, so we size and price to your roof and how you actually use power. CAE’s 24.6 kW system took about 69% off the bill, and a commercial system like it typically pays for itself in five to six years. We’ll put a real, numbers‑first projection of cost, saving and payback in front of you, not behind a sales pitch.

Will the installation disrupt my business?

It doesn’t have to. We planned CAE’s install around a live IT operation, so systems and staff were never disrupted. Site visit, design, install and commissioning, handled end to end and scheduled around you.

The bottom line

A power bill cut by 69%, with the difference staying in the business every year, made on the company’s own roof.
