In what is thought to be the first commercial installation in Charlotte where a building generates its own green power, workers and engineers from Cyclone Roofing installed a new solar array Friday on the roof of the Outfitter's Store at the U.S. National Whitewater Center. According to Tim Munson, a sales executive for Cyclone, the company attended a symposium there last year and was impressed by the facility. He said, "After holding a couple of our events there, we decided to donate a solar system to the Center as a marketing and educational tool. We purchased the system from Advanced Green Technology, our supplier of thin film solar panels, and worked with our other vendors to donate time and materials." The array is made up of 36 18-foot-long by 15-inch-wide flexible solar panels which each generate 136 watts of power. At full noon sun, the array is providing almost 5,000 watts of power to the Center's office building. Munson said that the polymer-based thin film technology is competitive with conventional crystalline cells because it generates power in low light. It is also lighter and simpler to install as it can be adhered to many commercial roofing materials. Panoramic Photo Composite by Gary O'Brien - gobrien@charlotteobserver.com
