Design Of Household Stand-alone PV Power Generation System

Now,the solar energy alternative energy sources is experiencing from the added energy to the development stage of history.Solar photovoltaic power generation technology as an important component of the solar energy utilization,and is believed to be twenty-first century one of the most promising way to generate electricity.Solar photovoltaic power generation system research to alleviate the energy crisis,reduce environmental pollution,and reduce the greenhouse effect has important significance.Because of the power electronic technology and photovoltaic battery technology rapid progress,and the degree to which new energy sources such as photovoltaic attaches great importance to the people's increasing,make photovoltaic power generation technology is developing very quickly.Based on the photovoltaic power generation system as an example to research,design.Is the current situation of the photovoltaic power generation and analysis of the first and the future development prospect,photovoltaic power generation system are introduced research status at home and abroad and the research direction of this paper;And then the classification of photovoltaic power generation system is introduced,the system composition of the independent photovoltaic power generation system is emphatically introduced.In the following,the principles and applications of solar panels,inverters,controllers and batteries are elaborated.In addition,the climate and lighting conditions in Beijing are taken as an example to calculate the optimal tilt angle of the photovoltaic cell panel.On the basis of meeting the needs of users,each formation was selected with models,allowing the configuration of the system to be the most reasonable and economical.
