This paper presents a novel method for selecting the optimum tilt angle and the optimum sizing of stand alone photovoltaic systems in accordance with different values of loss of load probability.The continuity uniformity and maximum of radiation on the surface should be considered comprehensively when the optimal tilt angle is determined.Assuming that average daily insolation on a tilt surface in a period of"Summer Half Year"and"Winter Half Year"is H l and H 2,respectively,the corresponding angle is optimum,when H l is equal to H 2 or before that H 2 has its maximum.With the simple calculation method of changing correlative depth of discharge,a series of array/storage combination corresponding to different LOLP can be achieved,thus optimum PV array and storage battery capacity can be obtained.
