A data centre, server room or tech facility runs a heavy, constant load, cooling and IT that never switch off, so the bill is relentless and resilience is everything. Rooftop solar won't cover all of it, and we won't pretend it can, but at this scale even a roof's worth of clean generation trims a large bill, hardens the site against a grid that can't blink, and turns unused roof into a working, ESG-friendly asset.
A data centre, server room or tech facility carries a load unlike almost any other: cooling and IT running at full tilt, around the clock, every day of the year. The bill is relentless and, more than anywhere, resilience is non-negotiable, because downtime is measured in money and reputation. Rooftop solar will not power a data hall on its own, and we won't pretend it can, but at this scale even a roof's worth of clean generation offsets a meaningful, always-daytime slice of a very large bill, from space that is otherwise doing nothing.
Paired with battery storage, solar also plays a resilience role: on-site generation and stored energy add a layer of protection behind your UPS and generators, and reduce exposure to a volatile grid and its prices. For a business whose whole product is uptime, that combination, lower cost and greater independence, is worth real money.
Technology and data companies are under growing pressure, from customers, investors and regulation, to prove their environmental credentials, and energy-hungry data infrastructure is a visible part of that story. On-site solar is a straight, evidenced answer for an ESG report, a customer supply-chain audit or a net-zero commitment, made real on your own roof rather than bought as an offset. Generated on your own roof rather than bought as an offset, that renewable energy cuts your energy bills and carbon footprint, powers EV charging, improves your energy efficiency, and answers the sustainability and net zero targets your customers now audit.
The finance works too. Solar turns unused roof into a fixed, low-carbon asset with a payback of roughly five to six years, then decades of near-free generation under a 25-year warranty. Qualifying commercial solar can be written down against tax. For a sector that plans capacity years ahead, a predictable, falling slice of the energy bill is a welcome certainty.
A data facility's roof is often small next to its load, so solar offsets a slice rather than the whole bill, and we won't pretend otherwise. What a big commercial roof does deliver is real. Here are the numbers from one we powered, the kind of asset we would build on your roof, then model against your actual load.
A big commercial roof we powered turned empty space into an asset saving up to £260,000 over its life. On a tech or data site the roof offsets a slice of a far larger bill, but every kWh you make is one you don't buy, and paired with storage it hardens your uptime. We would model your site's exact numbers before you commit, not after.

A commercial solar installation on a live technology or data site 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 uptime is never at risk.
The questions data and technology operators actually ask before putting solar on the roof.
No, and we won't pretend it can. A data hall's load is far larger than any roof can supply. What solar does is offset a meaningful, always-daytime slice of a very large bill from space that is otherwise doing nothing, and paired with storage it adds a resilience layer behind your UPS and generators. At this scale, even a partial offset is real money.
It doesn't have to. Almost all of the work happens on the roof, away from the data floor and plant. We plan around your change-control and maintenance windows, isolate only what is agreed, and design the connection so it never sits in the critical power path unless you want it to. Zero risk to uptime is the target we plan to hit.
Solar turns unused roof into a fixed, low-carbon asset with a payback of roughly five to six years, then decades of near-free generation under a 25-year warranty. Because your bill is so large, the pounds saved add up quickly even from a partial offset, and qualifying commercial solar can be written down against tax.
Yes, directly. On-site, metered generation is a straight, evidenced answer for an ESG report, a customer supply-chain audit or a net-zero commitment, real generation on your own roof rather than a bought offset, which increasingly matters to customers and investors in tech.
Yes. We design solar to complement your existing UPS, generators and any battery storage, adding on-site generation and stored energy that reduce grid exposure and support resilience. We engineer the interface to your requirements and standards.
Yes. A larger system needs approval from your Distribution Network Operator, and we manage that application and all certification for you, so you get a signed-off, compliant system without the paperwork.
