In recent years, the annual output of solar collector utilization in China accounted for the proportion of world output is maintained at more than 76% ownership of about 2/3 of the world. The use of solar thermal products have been exported to Europe and the United States and other developed countries, including the world's 200 countries and regions, favored by the residents and businesses in these countries to meet the needs of hot water heat in their daily lives . In 2011, China has 203 national export solar water heater products. As of the end of 2011, China has 168 million square meters of solar water heaters and annual savings of more than 2000 tons of standard coal. In accordance with the "12th Five-Year Plan in 2015, China solar water heater has to reach as much as 400 million square meters.
China is not only the world's largest producer and user countries of solar evacuated tube systems and solar thermal technology and equipment is also output to some countries and regions, support the development of the local solar industry. China's solar thermal industry is a national industry with independent intellectual property rights, control of the vacuum tube of the core components of the invention patents, as well as more systems integration technologies and equipment manufacturing technology. Some solar thermal companies by the United States, India, Vietnam, non-state investment or technology factories, the advanced technology of solar thermal utilization in China brought to the world. Some companies are still many countries and regions engineering design and construction of a large number of solar thermal utilization, and provide a model and reference for the local solar construction projects. Chinese solar water heater rely mainly on market forces to develop its spontaneous self-industry social service system is also worth abroad to learn from the reference.
