Macy's will be installing 8 megawatts of solar power in 26 stores throughout California. The installation will be performed by SunPower, a solar cell manufacturer. Macy's will buy the arrays for 11 of the stores. For the other 15 stores, Macy's will purchase the electricity produced by the solar panels from a third-party financier who will retain ownership of the systems. Additionally, the stores will be getting energy efficient upgrades, which will reduce its energy use by 40%, almost doubling the impact of the solar power alone. Specifically, Macy's will be integrating the solar power with efficient lighting, heating and cooling systems, and energy management systems.
Macy's is just another in a long list of big retailers who have gone solar. Other retailers now using solar power include: Estee Lauder, Kohl's, Target, Tiffany, Wal-Mart and BJ's Wholesale.
