A PV system design can be either approximate or precise. The approximate design is useful as it allows one to size the PV system without going much into the details of each component. But the efficiency of large PV systems can only be improved by precise sizing. There are various factors that should be incorporated in precise sizing of a PV system some of them are precise estimation of solar radiation data, information about battery Dod and PV array losses. All these factors have been considered in this paper for a precise sizing of stand-alone PV system for a residence in Nagpur (Maharashtra). Copyright@ International Science Community Association
