ALDI Narellan has become the latest store in the supermarket chain to become solar powered.
The Narellan store is among 250 in the country to have solar panels installed on the roof this year. A further six distribution centres will also be solar powered.
The switch to solar energy is part of the supermarket's pledge to convert to 100 per cent renewable electricity in Australia by the end of 2021.
It is estimated the roll-out of 102,000 solar panels at ALDI locations nationally will prevent 41,000 tones of carbon emissions from entering the atmosphere every year, which is the equivalent of 11,000 cars being taken off the road.
The company has already reduced its operational emissions by about 40 per cent since 2012, through using LED lighting, climate-friendly refrigerants and energy efficient chillers in store.
"We are excited about the role that ALDI Narellan now plays in contributing to a more renewable future for Australia," ALDI NSW manager director Alex Foster said.
"The switch to solar at the store is a significant step toward reducing our impact on the environment.
"It is our hope that we can continue playing a positive role in the local community and make our customers proud to shop at ALDI Narellan."
To meet the commitment of 100 per cent renewable electricity, ALDI has procured energy through two 10-year Power Purchasing Agreements (PPA).
