Summary:The installation of parallel-connected dc/dc converters allows energy and cost saving in photovoltaic (PV) systems. This paper develops a methodology with several algorithms to study the annual energy saving obtained with paralleled dc/dc converters in any world location. Moreover, this methodology allows one to select the minimum-cost size of a stand-alone PV system with dc/dc converter paralleling. For this purpose, a power-system sizing computer tool has been used, but its initial capabilities have been extended. The developed methodology allows for decision taking before investment is made.
