ALBUQUERQUE, N.M. — Kroger announced that two of its Smith's stores in Albuquerque, N.M., have installed photovoltaic energy panels.

The solar energy system on the roof of each Smith's store consists of 442 panels, each containing cells that convert sunlight into direct current electricity, Kroger said. Smith's was selected to be among the first Kroger division stores to install photovoltaic panels.

"We have done a lot of work over the last several years to integrate sustainable practices into our everyday business operations," Kroger president and COO Rodney McMullen. "Today, we are proud to unveil Kroger's first operational solar energy project. Smith's has done a tremendous job bringing this to realization. Kroger will continue reducing energy consumption and testing technologies that support future use of alternative energy sources."

Smith's operates 133 stores throughout seven western states.
