The Beijing Solar Energy Research Institute presented 303 sets of solar energy devices to Lhasa, capital of southwest China's Tibet Autonomous Region, at a ceremony held Monday.

Tibet, on the "roof of the world", has the plenty of sunshine with over 3,000 hours annually.

Apart from the 100,000 solar furnaces, Tibet has also built a number of houses equipped with heating systems using solar power.

Statistics show that the solar energy facilities now in operation in Tibet can save conventional energy resources equaling 120,000 tons of standard coal annually.

Beijing has donated a total of 603 solar energy devices to Tibet and is seeking international assistance to help Tibet spread solar energy usage.
