Spanish Supermarket Bon Preu Esclat Powered by SunPower Solar Systems
SunPower Dealer SUD Energies Renovables Selects High-Efficiency,
Non-Penetrating SunPower T10 Solar Roof Tiles for Bon Preu Esclat Stores
MADRID, Spain, June 2 /PRNewswire-FirstCall/ -- SunPower Corporation
(Nasdaq: SPWR), a manufacturer of high-efficiency solar cells, solar panels,
and solar systems, announced today that SunPower solar electric power systems
totaling 132 kilowatts have been installed on the rooftops of two Bon Preu
Esclat stores located outside of Barcelona, Spain. SunPower dealer SUD
Energies Renovables, S.L. of Vic (Barcelona) installed the systems, and
reports that they are working with the supermarket chain to install SunPower
solar power systems on additional Bon Preu Esclat stores over the next three
years.
A Bon Preu Esclat store in Piera, Spain received a 55-kilowatt SunPower
system, and a 77-kilowatt solar system has been installed atop the Bon Preu
Esclat store in Valls. At these locations, SUD Energies Renovables installed
SunPower(R) T10 Solar Roof Tiles, which are tilted at a 10-degree angle to
increase energy capture, and SunPower(R) 210 solar panels. SunPower panels are
up to 50 percent more efficient than conventional panels and up to 100 percent
more efficient than thin-film solar panels.
"We had two primary requirements for these installations. We wanted to
maximize the amount of power that could be generated within the limited roof
space, and we needed a lightweight system that would not require any roof
penetrations," said Manel Romero, technical director of SUD Energies
Renovables, S.L. "After investigating our options, including thin-film solar
electric products, we chose SunPower because it manufactures the highest
efficiency solar technology on the market today. Also, SunPower T10 Solar Roof
Tile systems are non-penetrating, lightweight and durable. The systems are
protecting the integrity of the rooftops, while delivering exceptional power
generation to the customer."
These installations for Bon Preu Esclat represent the first set of solar
systems in Spain using the SunPower T10 product on a commercial rooftop. In
the U.S., the T10 product has been installed on commercial rooftop systems for
SunPower customers such as FedEx, Wal-Mart Stores and Microsoft.
Also in Spain, SunPower has more than 45 megawatts of solar power plants
under construction.
