And solar photovoltaic industry is the main force foe the development of new energy industry. This paper points out the obstacles which improves the international competitiveness of China＇ s photovoltaic industry based on the analysis of the three big indexes, namely the international competitiveness of photovoltaic industry IMS, TCD and RCI, and proposes the suggestion which enhances the competitive advantage of China＇ s solar photovoltaic industry.展开更多

Energy crisis and environmental crisis prompted human thinking, looking for a way out. While fossil energy in the past hundred years time, the development of human society has made a huge role, but due to the limitations of its own： the non-renewable nature, environmental pollution and energy politicized, destined to be replaced. New energy in a tough energy and environmental situation become a new impetus for economic development. Of course, the new energy present due to various reasons, in the proportion of human energy consumption structure, the proportion accounted for far less than fossil fuels, technical issues, storage and transportation issues and cost issues still restrict the development and popularization of new energy. Nuclear, solar, wind, tidal energy and hydrogen energy are all new areas. Which in terms of nuclear and solar energy technology, the use is still relatively mature, the market prospects of other energy sources is also very tempting, in this paper, standing industrial perspective analysis of the market prospects of new energy solar and hydrogen energy.展开更多

DGPVi utilizes HyPV （hybrid PV） system which generates solar power for self-consumption in lighting and air conditioning in a production line of a factory when solar energy is available. It does not feed the excess PV power to the grid. HyPV will be switched to grid power supply when solar energy is not available. A 3 kWp DGPVi is installed in a factory for field demonstration. The test results show that the solar PV power generated can be utilized immediately. The solar energy generation efficiency （kWh/day per kWp PV installation） of DGPVi is close to that of grid-tied PV system without self-consumption and battery storage. The yearly return on investment of DGPVi is 2.0% at the present installation cost or 3.3% at further cost-down cost. The payback time will be 14.3 years at the present installation cost or 12.1 years at cost-down cost. The present study verifies the economic feasibility of DGPVi.展开更多
