Bentonville, Ark. -- Wal-Mart Stores, Inc. has installed eight solar photovoltaic (PV) arrays in Massachusetts.

The arrays contain almost 10,000 solar panels that Wal-Mart estimates will generate 2.8 million kilowatt hours (kWh) of energy every year, eliminating almost 1.5 billion tons of carbon dioxide emissions.

New York -- Walmart plans to install solar panels on about half of its stores in Massachusetts, making it the largest user of solar power in the state.

Walmart is partnering with Greenskies Renewable Energy LLC, Middletown, Conn., on the project, which involves 27 stores.

Lancaster, Pa. -- Giant Food Stores announced that roof-mounted solar photovoltaic systems have been installed and are operational at two of its locations in Lancaster and Pottstown. In-store flat panel monitors will reveal to customers in real time how the system operates and the energy savings being achieved.

West Chester, Ohio -- Ikea said Tuesday that it has officially plugged-in the solar energy system installed at its Cincinnati-area store in West Chester, Ohio. 

The 128,000-sq.-ft. PV array consists of a 1,026-kW system, built with 4,186 panels. Ikea West Chester’s program will produce approximately 1,334,300 kWh of clean electricity annually, the equivalent of reducing 1,014 tons of carbon dioxide, eliminating the emissions of 180 cars or powering 115 homes yearly.

Conshohocken, Pa. -- Ikea announced plans to install solar energy panels on 10 additional United States locations, its entire presence in the Southern United States.

Pending governmental permits, installation will begin this winter, with completion expected in summer 2012.

Collectively, the nine stores and one distribution center will total 10.7 Megawatts (MW) of solar generating capacity, nearly 45,360 panels, and a projected annual electricity output of 15,248,334 kilowatt hours (kWh).

When it comes to managing energy use, more and more retailers are looking to the sun — and are generating electricity on-site through solar roof panel installations designed to increase efficiencies and utilize a proven green power option. Chain Store Age talked with Michael Walker, director, commercial product management and marketing for Lennox Industries, about the growing retail movement toward solar power and how Lennox is leveraging the interest.


From Kohl’s to Whole Foods Market, retailers nationwide are utilizing solar power as a way to rein in energy costs. Still, solar energy remains victim of many misconceptions, according to Ben Collingwood, director of national accounts for REC Solar, a San Luis Obispo, Calif.-based solar power provider. Here are some of the most common:


Wayne, N.J. -- Toys “R” Us said Thursday it has completed a 5.38 megawatt rooftop solar power system at the company’s largest distribution center in Flanders, N.J.

The solar roof is estimated to offset 72% of the electrical needs for the Toys “R” Us facility, making it the largest operational rooftop solar installation in North America.

Tejon, Calif. -- Ikea on Wednesday flipped the switch on a newly constructed solar energy system at its southwestern U.S. distribution center in Tejon, Calif. The 370,000-sq.-ft. solar array consists of a 1.8 MW system designed and installed by California-based REC Solar, and built with 7,980 REC Group panels.

Bentonville, Ark. -- Walmart announced the deployment of five rooftop solar arrays for Walmart and Sam’s Club locations in Puerto Rico. The solar program is made possible through a solar energy service agreement where Sun Edison, a subsidiary of MEMC Electronic Materials, will design, deploy, operate and maintain over three megawatts of solar technologies across the five locations with no upfront costs to Walmart.
