The new swimming complex, built on the campus of the Georgia Institute of Technology for the 1996 Summer Olympic Games, features a large-scale solar electric system.  A 340-kWp rooftop PV array was installed on the main structure, and a custom arched glass PV canopy was designed for the entrance to the complex.  The rooftop PV system employs 2,832 Solarex Corporation 120-W PV modules mounted above the steel roof deck to allow for the free flow of cooling air below the array.  A central, Kenetech 300-kW DC-to-AC inverter feeds three-phase power into the campus utility grid.  The total array has an area of some 3,043 square meters and is the largest system of its kind in the world.  The new entry canopy of the natatorium features special large-area 250-W Solarex AC PV modules that have a clear back skin, to allow light transmission between the individual crystalline cells.  The PV modules form the canopy and are integrated in a special arched aluminum support structure custom-fabricated by the Kawneer Company.  Each PV module has its own integrated DC-to-AC micro inverter, developed by Advanced Energy Systems, to deliver 60-Hz AC power directly to the building complex.  Shown here, the entry canopy.
