Aldi is investing £17.5 million in over 200 of its UK stores to expand its use of solar energy. The supermarket chain plans to install solar panels between 2027 and 2031, bringing its total investment in solar power to around £26 million.
The new solar panel installations will allow Aldi to produce a greater share of its own renewable electricity, helping to reduce its reliance on the national grid. Each system is expected to generate enough power to supply up to 30% of a store’s annual energy requirements.
Aldi’s investment forms part of its wider commitment to renewable energy, following an earlier £8.4 million programme to fit solar panels at 100 stores during 2025 and 2026. By the end of 2026, over 500 of its stores are expected to be equipped with solar power systems.

Aldi UK managing director of national real estate Jonathan Neale said: “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.”
By generating more of its own electricity, Aldi can reduce its reliance on the grid and make its stores more sustainable. The announcement is part of Aldi’s wider investment in its UK estate, which includes a £300 million commitment to refurbishing and expanding existing stores during 2026.
The upgrades will also include energy-efficiency initiatives, such as installing doors on refrigerated cabinets and using natural refrigerants. These measures are designed to cut energy consumption and help lower the company’s carbon emissions.
