Suniva, which was chosen as the supplier for the solar roof, is an Atlanta-based solar-cell and module manufacturer. Suniva secured $50 million to build a commercial production facility in Atlanta in February 2008. The company licensed technology invented at Georgia Tech: extremely thin high-efficiency mono crystalline silicon solar cells that are less than 100 microns thick and claim 20 percent efficiency.
The stadium was built for the 2010 Commonwealth Games taking place October 3-14, the Olympics equivalent for former British territories, colonies, and existing commonwealth members. (About 71 countries participate including Australia, Bahamas, Canada, Kenya, and New Zealand.)
It's the first time India has ever hosted and the New Delhi organizing committee for the games has promised that this will also be the first ever "Green Games." In an effort to be carbon neutral, the committee pledged a series of green venue initiatives including rainwater harvesting, green waste management, sustainable public transport options, energy-efficient fixtures for venue interiors, solar-based lighting for venue exteriors, eco-friendly construction materials, and planting three city forests of trees.
The solar plant on top of Thyagaraj Stadium goes toward that end.
Suniva, which installed 3,640 of its 280Wp modules on top of Thyagaraj Stadium, expects the solar roof to generate approximately 1.4 million kilowatt-hours of electricity per year.
