IEEE Guide for Array and Battery Sizing in Stand-Alone Photovoltaic (PV) Systems

A method for properly sizing the PV array and battery for stand-alone PV systems where PV is the only charging source is recommended (in conjunction with IEEE Std 1013(TM)). Load calculations and determination of solar radiation in the sizing of the system need special attention. Additionally, the critical nature of the load in deciding an acceptable annual availability needs to be considered.
