Use of solar power technology solar principle is not very popular, the use of solar power there are still high cost, low efficiency problem, but in terms of satellite solar cells provide energy has been applied. Solar energy is the energy of nuclear fusion reactions inside the sun or sunspot surface continuously generated. The average solar radiation intensity on the Earth's orbit is 1369w / m. Earth's equatorial circumference to 40000km of photovoltaic power generation, which calculated the energy the Earth get up 173000TW. Standard peak intensity at sea level is 1kw / m2, the Earth's surface to a point 24h annual average radiation intensity is 0.20kw / m, equivalent of 102000TW energy, the energy dependence of human survival, including all other forms of Renewable energy (excluding geothermal resources) photovoltaic power generation, although the total amount of solar energy resources equivalent to the current human use of energy ten thousand times, but the low energy density of solar energy, and it varies from place to photovoltaic systems, as time changes This is the main problem facing the development and utilization of solar energy. PV relevant national energy policy Article IV State Council department in charge of the country distributed PV planning guidance and supervision; local energy authorities in charge of the energy sector under the guidance of the State Council, responsible for the area of ??distributed photovoltaic power generation planning, supervision and management of construction; National Energy Board the agency responsible for the area of ??distributed PV planning and policy implementation, and network operation, the market fair and safe operation of PV power installed to regulate the price, day-solar power (certified), East Lake PV from Wuhan Tianhui Giant Technology Limited. Wuhan Tian Hui Ju Technology Co., Ltd. (www.thjnkj.com) (www.thjnkj.cn) is Wuhan, a leader in solar and renewable energy, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In day-solar power leadership with the staff warmly welcome all inquiries negotiations to create day-solar power a better future.
