The "Commercial Regional Top Producer of the Year" award honours the SunPower commercial dealer that has the highest shipment volume in their region of the United States. In 2013, Santa Clara-based Vista Solar installed the largest privately owned commercial solar power system in Fremont, Calif. The 920-kilowatt rooftop installation features the Sun Power E Series solar panels with an efficiency of 20 percent. Using such high-efficiency panels allowed the building owner to maximize underutilized roof space by installing solar, and see electricity savings of nearly $250,000 in the first year. The system is expected to generate savings of more than $7,000,000 over its 25-year lifetime.

"We congratulate Vista Solar for their extraordinary sales performance in 2013," said Howard Wenger, SunPower president, regions. "As a SunPower Commercial Dealer, they have demonstrated a level of quality and commitment to excellence exceeding our expectations, and we look forward to their continued success in 2014."

Jaymes Callinan, vice president of Vista Solar, said partnering with SunPower allows his company the ability to offer customers reliable solar energy and electricity savings over the life of their systems.

The SunPower dealer network includes more than 1,800 dealers worldwide, with approximately 400 located in the U.S.
