Abstract:With the development of society, the human the demand for power has indispensable, can use all sorts of human beings Source into electrical energy. Solar pv with its clean, inexhaustible and by all countries' energy experts after Holding, especially (pv) power is the world hot technology research. This paper first analyzes the energy crisis form

   The development of the industry of photovoltaic system market, in the full analysis of the countries (pv) power policies and the advantages and disadvantages of the entity

   The basis, through local families of power consumption of the investigation, and then get the battery needed power component. In the actual measurement of housing, select the appropriate installation site, ground and equipment choice .Not only for the selection of quality and use the security, considered the best economic benefit, wiring requirements.Also use the most short. At the same time, also on photovoltaic module, battery pack, controller, inverter, etc.The application of a series of protection measures.

Key words: Solar energy，Photovoltaic (pv)，The actual measurement，Location         select material，Power

　　　在本次设计中主要是根据对家庭用电的总功率和应急负载用电量调查以及对家庭用房的实际测量，通过计算，再结合地理纬度所得的最佳日照角度，然后对太阳能电池组件，蓄电池，控制器，逆变器选型，再根据家庭实际状况在对设备部件设计以及安装。通过计算得所需要的总电池板的电池板的面积，找到能满足要求的地方进行安装。最后根据各种设备的价格算出整套设备的价位。

　　　本次设计的指标为：（1）白天电能自动存入蓄电池，夜晚或者阴天，蓄电池给一般负载供电，然而当发生什么重大灾难，可以通过手动使蓄电池给应急负载供电，并且手动使蓄电池与一般负载断开。
