The supermarket chain’s investment will see solar panels fitted at an additional 230 stores across the UK from 2027 to 2031.
Designed to help Aldi generate more of its own renewable electricity, the latest commitment builds on the company’s previous £8.4 million programme to install solar panels at 100 stores during 2025 and 2026.
The firm said each installation will be capable of providing up to 30% of a store’s annual energy requirements.
Once completed, the latest programme will bring Aldi’s total investment in solar power to £26 million, with more than 500 of its UK stores expected to have the renewable technology fitted by the end of this year alone.
Jonathan Neale, managing director of national real estate at Aldi UK, said: “We have plenty of space on our store roofs, so it makes sense to use it.
“We want solar power to become a normal part of how we run our stores, and this investment will help us bring it to even more locations over the coming years.”
He added: “By generating more of our own electricity, we can reduce our reliance on the grid and make our stores more sustainable.”
The announcement forms part of Aldi’s wider investment in its UK stores. Earlier this year, the supermarket announced plans to invest more than £300 million in upgrading and extending existing stores in 2026, including the introduction of energy-saving features such as fridge doors and natural refrigerants to help reduce carbon emissions.
The retailer is also recruiting for 600 roles at its new automated distribution centre in Bardon, Leicestershire.
The new jobs will be in warehouse operations, logistics and transport at the supermarket chain’s 1.3 million sq ft distribution centre.
According to Aldi, the facility will be the UK’s largest supermarket distribution centre, capable of moving around seven million pallets each year to support stores across the Midlands and beyond.
