Why is it important?
By means of data obtained in climatic stations the electrical generation capacity of these stations is shown to optimize the design of power converters. The characteristics of photovoltaic cells was analysed by means of mathematical modelling using the single-exponential model. With the meteorological data and using the concept of weighted efficiency established by IEC 61683 it was calculated the weighted average efficiency of photovoltaic systems in three cities of the Brazilian State of Santa Catarina: Indaial, Florianopolis and Itajai.
Perspectives
The equations obtained serve to make analysis about the potential of solar generation, optimizing the efficiency of photovoltaic generation system allowing the investor to know the payback level and the return time of a possible investment in the area analyzed.
