Abstract: On account of the limited non-renewable energy and enlarging energy consumption, solar seems to be an alternative, because it is free, clean and extensive, and can be changed into different energy forms. In

this case, photovoltaic (PV) system is utilized to convert sunlight into electricity directly and is widely applied all around the world. This report is based on a PV laboratory and provides an opportunity for people to acquire a comprehensive understanding of characteristics of PV system, especially the influencing elements on electricity generation of PV system. A series of tests would control variables, such as the circuit ｌｏａｄ, the irradiation and connection type, to investigate the behavior of PV modules. The data presented in the following content reveals the specifying links between them. For the efficiency part, factors would be raised to analyze the distance between the results and normal data.
