Abstract In today's society is face many problems such as environmental pollution and energy shortage。 Sharply in recent years, with the industrial development, the use of too much energy such as coal, oil, produced a large number of nitrogen dioxide, sulfur dioxide, contributing to the greenhouse effect and fog etc。 Bad phenomenon to appear,this makes the human survival environment suffered serious destruction, has now reached a direct threat to human life and property safety。 Energy crisis alarm has been in our side think of, so quick to find solutions to these problems, make full use of clean energy and renewable energy to become the choice to solve these problems。 And solar power generation technology naturally become one of the main channel to save the urgent need, this paper will study the photovoltaic (pv) grid power generation technology is the development trend of solar photovoltaic power generation。 Next we will generally expounds the composition, application status of solar photovoltaic power generation systems。 Mainly to learn about grid systems and solar photovoltaic power generation technology and application。
Key words; The energy crisis; Solar photovoltaic power generation system; Photovoltaic (pv) grid technology and applications
