“…The annual surface absorption of solar energy is equivalent to the energy of 1.7 trillion tons of standard coal, which gives good conditions for the utilization of solar energy, especially in the northwest, Tibet and Yunnan Province, and other areas which are particularly rich in solar energy resources. IJESM 3,1 In the application of solar PV, from 2002 to 2004, the state organized and implemented the "make electricity available to the countryside" and provided ¥4.7 billion to build a number of independent renewable energy power plants in 1,065 township of 12 provinces such as Inner Mongolia, Qinghai, Xinjiang, Sichuan, Tibet and Shanxi, etc. These plants include photovoltaic, small hydropower and other forms of plants, of which photovoltaic power plants account for most of the whole, and the application of 17,000 kW photovoltaic batteries has promoted the development of domestic PV industry.…”
