Environmentally friendly rooftops may soon be coming to a local grocery store.

Whole Foods announced today that it plans to install solar panels through Elon Musk’s SolarCity and NRG Energy partnership at up to 100 stores. While the store locations have not been released, NRG says they will be installed at up to 84 locations. SolarCity did not release how many they plan to install.

Whole Foods has nearly 431 stores across the United States, and will become one of the top 25 corporate solar users in America once the installations start.

A Whole Foods spokeswoman says installing solar panels at Whole Foods Markets will increase the amount of renewable energy that is generated in communities where Whole Foods stores are located. Direct Energy Business already provides solar services to Whole Foods and SolarCity will design the solar systems and sell electricity.

Installation of the solar panels will start next month.
