This paper presents a Levelized Cost of Electricity (LCoE) model that was firstly developed for conventional photovoltaic (PV) modules integrated in four different PV configurations: fixed; tracking (1-axis and 2- axes); and concentrated photovoltaic (CPV) systems, the DoubleSun® technology. Such analysis highlighted that as the complexity of the PV system increases (e.g. tracking structures, optics, etc.) additional costs appear and the relative relevance of the module cost decreases. However, a significant decrease of the cost of standard modules may reduce the advantage of other configurations as to the conventional flat plate, suggesting the need for higher concentration levels. Thus, the LCoE analysis was then used as an auxiliary design tool for the development of the new HSUN concept, a new medium CPV system that is being developed by WS Energia. By establishing the target of grid parity, the model has pointed out that the optimum level of concentration for a new CPV technology, the HSUN concept, must lie within 15-20 suns.
