Weighted average efficiency and analysis of investment of photovoltaic systems in the Brazilian State of Santa Catarina

This paper analyses the solar radiation profile of three cities of the Brazilian State of Santa Catarina and shows the calculation of the weighted average efficiency, aiming to allow efficiency maximization designs for the electrical energy processing in photovoltaic systems. By means of data obtained in climatic stations the electrical generation capacity of these stations is shown to optimize the design of power converters. It is shown the results for the cities of Indaial, Itajai and Florianopolis. In addition, investigates the economic potential for the use of photovoltaic solar energy in homes, these calculations allow us to estimate the maximum efficiency of electricity generation from solar photovoltaic systems.
