UK’s largest on-site solar array installed

The installation of the UK’s largest single roof mounted solar panel array on its distribution centre

Marks & Spencer (M&S) has completed the installation of the UK’s largest single roof mounted solar panel array on its distribution centre in Castle Donington, England.

The solar PV array will span the site’s 900,000 sq ft roof and will generate over 5,000 MWh of electricity per year, the equivalent amount of energy to power 1,190 houses.

The 24,272 PV panel structure, which would cover 25 miles if the panels were laid end to end, will lower M&S’s carbon footprint by 48,000 tonnes over 20 years. The energy generated will provide nearly 25% of the energy required for the fully automated distribution centre.

The record-breaking PV array will help M&S maintain its commitment of sourcing 100% of its electricity for UK and Ireland buildings from renewable sources, with 50% sourced from small scale renewable sources by 2020.

Amber Rudd, Minister for Energy and Climate Change, said: “There is massive potential to turn our large buildings into power stations ” and this is a great example of how businesses can reap the benefits.”

The project is the first of a number of onsite renewable initiatives set to be rolled out this year by M&S, and is another step on the retailer’s carbon reduction journey. Since the launch of Plan A in 2007, M&S has lowered its carbon emissions by 37% and is carbon neutral across its worldwide operations.

M&S has agreed a Power Purchase Agreement with leading infrastructure specialist Amber Infrastructure, which will be supplying and maintaining the 6.1MWp solar panel array, having now completed its installation. The agreement runs for 20 years, with commitment from M&S to purchase all the electricity generated by the solar panels.
