SolarPower: Spanish Supermarket chain goes green

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.
