MADRID, Spain, October 14 /PRNewswire/ --

SunPower (Nasdaq: SPWRA, SPWRB), a manufacturer of high-efficiency solar cells, solar panels and solar systems, and The Naturener Group, a Spanish-based company, today dedicated a 7-megawatt solar electric power plant in Casas de Don Pedro, Badajoz, Spain.

"The SunPower Tracker solar power system is a proven and reliable solution for maximizing the highest energy delivery, while optimizing land use and reducing related costs."
