Bentley puts factory roof to practical use

Over 20,000 solar panels with a capacity of 5MW have been installed on the roof of Bentley Motors' factory in Crewe, Cheshire.

The array occupies 3.45 hectares of roof space, and Bentley says the system is three times more powerful than the current largest roof-mounted system in the UK.

At peak generation times, the system is expected to produce up to 40 per cent of the plant’s energy requirements, reducing its CO2 emissions by over 2,500 tonnes per year.

The installation is owned and operated by Lightsource Renewable Energy, which will supply locally generated clean energy to Bentley through a power purchase agreement.

Michael Straughan, Bentley’s member of the board for manufacturing, explained: “Unlikely as it may seem, our 1940s plant in Crewe is ideally situated to generate solar power, as the ‘saw tooth’ factory roofs are south facing at an angle of 20 degrees. We take the sustainability of our products and factory extremely seriously and we are always looking for ways to reduce emissions and improve energy efficiency.”

Bentley Motors employs around 4,000 people in Crewe, which is home to all its operations including design, R&D, engineering and production.
