Solar power train efficiency in solar power generation system, the overall efficiency of the system by the PV conversion rate ηese battery pack, the controller efficiency, battery efficiency, efficiency inverter efficiency and load of other components. But with respect to the solar cell technology in terms of technology and production levels of solar power principle than controllers, inverters and lighting loads and other elements much more mature solar power, and the conversion rate of the system is only about 17%. Therefore, to improve the conversion rate of the battery pack, reducing the unit cost of power is solar power industry of the important and difficult. Since the advent of solar cells, crystalline silicon material as the protagonist holding a dominant position. Research on silicon cell conversion rate increased mainly around the energy-absorbing surface, such as double-sided solar cell market, reduce the reflection; the use of technology to reduce the gettering compound semiconductor material; ultra-thin battery technology; improve theory, new model; condenser batteries. Several solar cell conversion efficiency of a solar cell applications application of solar cells from the military field, enter the aerospace industry, commerce, agriculture, communications, home appliances and utilities sectors, especially in remote areas can be dispersed, mountains, deserts, islands and rural use of solar power rate of return, in order to save the cost of expensive transmission lines. But at this stage, it costs still high, issue 1kW electricity need to invest thousands of dollars, so the large-scale use is still limited economy. Solar power market, riverbank solar power, day-solar power provided by the Wuhan days-Technology Co., Ltd. giant. Wuhan Tian Hui Ju Technology Co., Ltd. (www.thjnkj.com) (www.thjnkj.cn) strong, credible, in Wuhan, Hubei solar and renewable energy industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead day-solar power into the brilliant and you work for a better future!
