The group said it was one of the largest private solar installations in Britain. 

It covers more than 7,500sqm of roof space and is comprised of 3,680 individual panels. 

Group ESG director Lucy Klinkenberg said the installation would “significantly enhance” Paragon's sustainability credentials and would also contribute to its broader environmental goals.

"The new system is projected to generate an impressive 1.6 million kWh of self-generated electricity annually, leading to a substantial reduction of approximately 20% (331 tons) in Scope 2 carbon emissions a year,” she explained.

“Beyond the immediate environmental benefits, this investment also bolsters Paragon's energy independence, mitigating exposure to volatile market energy prices and securing a more sustainable operational future.”

The amount invested in the new setup was not disclosed.

The group is exploring the potential to add similar solar arrays at other suitable sites that are owned by the business.

There will also be a digital display at Dagenham so employees can see live data on the energy being generated. 

Dave Phillips, business line COO at Paragon UK, described it as a pivotal moment in Paragon’s sustainability journey.

He commented: “We are immensely proud to implement one of the largest private solar arrays in the UK, significantly reducing our carbon footprint and driving us closer to our ambitious Net Zero targets.

“This investment is not just good for the planet; it's good for our business and our stakeholders. We implement locally to impact nationally.”
