Solar power will play an important role in several key pavilions at the Shanghai 2010 World Expo, experts told a Yangtze River Delta science forum held yesterday in the city to discuss energy and sustainable development.

Solar-influenced construction will be used at the China Pavilion, Expo Center and the Theme Pavilion, where the slogan "Better City, Better Life" will play out. Solar lamps and solar-energy fixtures such as toilets and information boards will also be adopted, using batteries for storage.
