Community Energy Solar, Radnor, Pa., has closed financing and commenced construction of its 6MW Keystone Solar Project in Lancaster County, Pa. Exelon Generation and Community Energy's retail marketing division committed to buy the output and back the financing for the project. Several early high-profile customers have already signed up for a share of the output, including Franklin & Marshall College, Eastern University, Clean Air Council, and most recently, the Philadelphia Phillies and Millersville University.
The solar panels are being installed on driven posts without concrete to avoid soil disturbance, such that the site will be maintained with selected cover vegetation to preserve and improve organic soil content. About 20,000 Canadian Solar 290W modules are being installed on fixed tilt, ground-mounted aluminum racking provided by Schletter and will be interconnected to the PPL Electric grid at 12 kilovolts with Advanced Energy inverters and platforms. The project will supply about 7.5 million kilowatt hours per year of solar generated electricity under a fifteen-year power purchase agreement with Exelon.
