Two workers install solar panels over the curved roof of Beijing's National Indoor Stadium, dubbed with 'Bird's Nest', June 19, 2007. Beijing News reported that the host city has finished the installation of a total of 1,124 solar panels, with a lifespan of about 25 years. 1,100 of them have been installed atop the roof, each spanning 1.2 meters long and 0.8 meters wide. The other 24 replace the glass curtain wall on the stadium's southern face. When the solar modules are put into use, they are expected to save 904.8 tons of standard coal in their lifetime.
