Air Liquide is a World leader in gases, technologies and services for Industry and Health and is present in 80 countries with more than 50,000 employees and serves more than 2 million customers and patients. Oxygen, nitrogen and hydrogen have been at the core of the company’s activities since its creation in 1902. Air Liquide’s ambition is to be the leader in its industry, delivering long-term performance and acting responsibly.

In September 2015, Air Liquide made the decision to install a solar PV system at their UK head office in Coleshill. As well as being important to their sustainability objectives, this would serve as a pilot, with the possibility of further installations in the future.

Air Liquide is committed to optimising their environmental footprint, so utilising energy from sustainable sources was a key factor in their decision to install a PV system, allowing them to act responsibly and bring value to their stakeholders.

Air Liquide’s brief was to install a system as close to 250 kWp as possible. After a detailed survey, EvoEnergy proposed splitting the system over three areas of the site utilising 876 x 275W Trina panels and Solar Edge optimisers that would enhance the performance of each panel and minimise the impact of some minor shading issues. SolarEdge technology also meant that each panel could be monitored individually.

Because Air Liquide wanted to maximise the system’s output in challenging conditions they needed to work with a supplier who utilised the best technology available, had extensive expertise and offered a full maintenance plan.

At Air Liquide, safety is the number one priority, and during the installation, which took 3 weeks, various types of mounting frames and fixing methods were used to fit the system onto different roof types across the site.

Abel Merloiu, Environment & IMS Officer for Air Liquide UK, commented;

“This is the largest PV system installation at an Air Liquide UK site and we are delighted to have worked with EvoEnergy. They have delivered a complex system on time and within budget, despite adverse weather conditions and have adhered to our very stringent health and safety standards.  It has been a pleasure working with the team and I can endorse their quality customer-focused solutions.

Now complete, all of the solar energy generated onsite will be used by their intensive 7 day a week operations expected to be around 224,182 kWh per year, also reducing the company’s carbon footprint by over 100 tonnes annually.
