Solar radiation heat. China's 1.3 billion people, 3.5 million households, if the daily supply of 60 ° C per 100 liters of hot water, 664,300,000,000 to be the year of electricity, the country spent almost half of the annual generation capacity, electricity is about 4000 Billion at a cost significantly. As the market demand, solar water heaters is the use of light and heat of the most successful in the field. China's solar water heater in the fundamental research, material research, applied research, technical standards, the level of manufacturing, product quality, in the whole of the international advanced level, a number of leading international indicators.

China's solar water heaters involved in the production, sale and installation services business has more than 1,000, the amount of water heaters to maintain 10,000 square meters over 4000, sales of solar water heater production and installation of the first area in the world. In 2002, solar water heater production of about 10,000,000 square meters, the output value of 110 billion yuan of output value has reached more than 10 billion super-family. Plan By 2005, China solar water heater with an annual production capacity up to 11,000,000 square meters, to maintain the total volume of 64,000,000 square meters, then these two figures may be a breakthrough. At present, solar water heaters are glass vacuum tube-type heat pipe vacuum tube, flat panel and a small amount of sun-stuffy, glass vacuum tube-type accounts for more than 80%. China's future government, industry associations and related businesses in the solar water heater industry is the focus of attention should be given to:

       (1) to further standardize the market, to secure Lingtou Su to ensure sustained and healthy development of the industry;

       (2) increased government support, business innovation and technology to strengthen and improve the level of the industry as a whole and equipment, foster a number of international enterprises Jingzheng Li;

       (3) to speed up construction and integration of solar energy research and demonstration work, and strive to break through as soon as possible;

       (4) to strengthen international exchanges and cooperation, and actively introducing foreign capital and advanced technology, the expansion of Japan, to jointly promote the development of China's solar water heater industry;

       (5) vigorously promote a good job. Education, training and information work.

       The use of solar thermal, solar water heaters in addition, there are the sun room, solar cookers, solar greenhouse, solar drying systems, solar disinfection of the soil to kill Yin technology, these technologies, particularly in northern and western parts of a wider application, and achieved remarkable results.

       Solar thermal use of solar thermal power generation is an important aspect of this technology is the use of solar radiation collectors to heat water heating together for the production of steam, and then through the steam turbine, generator for power generation. According to the collector in different ways and at high temperature and low temperature power generation. The United States, Japan, Italy and other countries in the solar thermal electric power generation than the leader, China has just begun.

       If the all-round solution to the solar hot water inside the building, heating, air-conditioning and lighting can be used, it will be the best option, solar energy and construction (including the high-level) integration and implementation of the research, development and utilization of solar energy in the future is an important direction, but also The solar energy industry as a whole make a big root of the problem. Although this regard, there is no substantial progress, but because of the demand for the efforts of the world, I believe there will be a breakthrough soon.
