Calculating method of the capacity of photovoltaic array and battery considering power failure probability in stand-alone PV systems

摘要

In this paper, the way to decide the most suitable capacity of photovoltaic arrays and batteries in stand-alone PV power systems is suggested. It is decided based on the parameter PFP (power failure probability). The designer can make the nomogram using the suggested method to decide the most suitable capacity of array and battery from the location of the system, the load patterns, and the climate data. An example of deciding the capacity of arrays and batteries in Tokyo from the calculation and the derived nomogram is presented.
