Canadian Solar Announces Sponsorship of New York Yankees

Founded in 1903, the New York Yankees are considered to be Major League Baseball's most successful franchise. The New York Yankees have won 27 World Series championships and 40 American League pennants. The team has featured some of baseball's best known, most dominant players, including Babe Ruth, Lou Gehrig, Joe DiMaggio, Mickey Mantle, Yogi Berra, and recently Derek Jeter and Alex Rodriguez. Forty-three Yankees players and eleven Yankees managers have been inducted into the Baseball Hall of Fame, and the team has retired the numbers of 16 people.

Dr. Shawn Qu, Chairman and Chief Executive Officer of Canadian Solar, commented, "Canadian Solar is proud to become an official sponsor of the iconic New York Yankees.  The New York Yankees have always transcended the sport of baseball, with the franchise recognized globally for its championships, professionalism and excellence. Canadian Solar also represents excellence to solar customers worldwide, backed by our history of technology innovation, proven performance and superior customer service.  By joining with the New York Yankees, we can now leverage one of the world's most powerful, global brand-building platforms to further expand awareness of Canadian Solar and our innovative, affordable, cost effective solar energy solutions."

Since its opening in 2009, Yankee Stadium has made a strong commitment to raising environmental awareness. Various waste-reducing activities, including the establishment of the Yankees Sustainability Facility Program, have helped promote responsible energy consumption and community improvement. The program ensures the efficiency of all equipment while focusing on energy reduction. During the 2010 season, waste management, composting and recycling helped divert more than 35 percent of Yankee Stadium's trash away from landfills. Additionally, close to 9,000 gallons of cooking oil used in the Stadium last year was converted into roughly 7,000 gallons of biodiesel fuel.

"We are extremely pleased about our new relationship with Canadian Solar," said Michael J. Tusiani, Yankees senior vice president of corporate sales & sponsorships.  "We hope its in-Stadium signage will strengthen the importance of environment attentiveness, which is a significant platform for our organization."

The solar industry grew 101% in the USA in 2010 creating over 93,000 jobs, making it one of the fastest-growing industries in the United States.
