Some applications of recent R and D experiences in the sizing of stand-alone photovoltaic power systems
Stand-alone photovoltaic (PV) power systems have become a cost-effective energy source for various applications. As the demand for stand-alone PV power systems grows, more importance is placed on improving system cost-effectiveness and reliability. Sandia National Laboratories is responding to this need through the development of detailed PV performance models which are being employed as the basis for simplified design methods. This paper outlines some of the most important conclusions from this work including the application of PVFORM, a computerized systems simulation model in optimizing a PV system configuration. Specific examples are presented and the use of the model is described with respect to determining the most cost-effective component configuration in a stand-alone PV system. Also outlined is an analysis of the expected long-term performance of a stand-alone PV system with respect to its capacity to service the load reliably.
