Per a SunPower press release:
Macy's is launching a program to install solar electric power systems at 28 California stores, including 15 in Southern California. SunPower Corporation (Nasdaq:SPWR), a Silicon Valley-based manufacturer of high-efficiency, solar cells, solar panels and solar systems, is partnering with Macy's to design and install the systems. . . .
Through its 28-store partnership with SunPower, Macy's has committed to installing a total of 8.9-megawatts of solar power systems on its California stores. In addition, SunPower is assisting Macy's to improve the energy efficiency at the stores. Combining solar power with energy efficiency will allow Macy's to achieve an estimated 40 percent reduction in utility-provided energy, almost doubling the impact of the solar power alone. . . .
For 17 of the 28 stores, Macy's will purchase solar-generated electricity under the SunPower Access(tm) program, a solar services agreement that allows the retailer to purchase just the electricity generated at its stores -- not the solar power systems. At the end of a 10-year term, Macy's will have the option to renew the agreement, transfer the equipment to a new site, or buy the system. Macy's will buy solar power systems for the remaining 11 stores through an outright system purchase.
SunPower commercial 300 series solar panels deliver panel efficiencies of up to 19.3% and are backed by a 25 year warranty.
The company is headquartered in San Jose, California and is a subsidiary of Cypress Semiconductor Corporation.
This is a very large commitment by Macy's and with a potential energy savings of 40%, with energy efficiency improvements, demonstrates that solar power combined with energy savings has a great potential, even at the present time, in areas where there is high solar radiation. There are large incentives in California, as well as high solar radiation, which enable such installations now and help develop a solar industry that can be incentive free when production costs are reduced as they most certainly will be in the next 3 to 5 years.
