IEEE Draft Guide for Array and Battery Sizing in Stand- Alone Photovoltaic Systems Prepared by the Energy Storage Subsystems Working Group of the IEEE Standards Coordinating Committee 21, Fuel Cells, Photovoltaics, Dispersed Generation, and Energy Storage Committee

This guide provides information to assist in sizing the array and battery of a stand-alone photovoltaic (PV) system. Systems considered in this guide consist of PV as the only power source and a battery for energy storage. These systems also commonly employ controls to protect the battery form being over or under charged, and may employer a power conversion subsystem (inverter or convertor).
