Shanghai Solar Technology Co., Ltd is a Sino-America jointed company with its support from American TSUN Energy Technology Company. It focuses on the R&D, production and sales of the solar energy series products. The main production center is in China while its corn technology is brought from America. Because of the non-regeneration and pollution of the traditional energy, while the human beings create the industrial civilization and pursue for realization of perfect living status, they increasingly destroy the self-living environment and pay heavy cost: energy crisis, air pollution, soil and water loss, vegetation regression, ELNINO, red tide, soil and water sources heavily pollutedâ?¦ Today, the oil, gas, coal etc traditional resources, as the basis of the modern human civilization only can last one more century. The air, soil and water sources have been heavily polluted. More and more areas are not suitable for residence any more. If it cannot make right-about, the human civilization will collapse with exhaust of the traditional energies and deterioration of natural environment. The existence of the human beings and the human society is looming and the energy saving and environment protection have become the common desire of all countries. The solar energy has many advantages, such as â??unlimitedâ?? reserves, generalization of existence, cleanness of development and utilization and gradual disclosure of economy. The solar energy serial products, such as the solar water heater, solar power generation home system, solar power generation engineering system and solar lighting etc, are very popular among the people because of non-pollution, energy-saving, environment-friendly, safety and null expense at the time of using etc. Its development and utilization is the effective approach finally solving the energy deficiency, environment pollution and greenhouse effect etc problems caused by the regular energy, especially the petrochemical energy. It is the ideal substituting energy for the human being.
