Rendimento de módulos fotovoltaicos sob condições específicas do espectro solar incidente na Serra Gaúcha

Abstract

The purpose of this work is to determine the degree of influence that the meteorological and geographical conditions of Farroupilha city feature on the photovoltaic energy production capacity and also on the efficiency of the three main modules technologies for photovoltaic conversion present in the world market and, therefore, in the correct sizing of cogeneration systems connected to the local power grid. The behavior of the different technologies of photovoltaic panels will be determined by the spectral responses obtained by scanning graphic tested by internationally recognized institution and the generation of monthly average spectra of solar radiation is determined by the insertion of meteorological data of fourteen years of measurements provided by National Institute of Meteorology and tested on the SMARTS software 2.9.2 (Simple Model of the Atmospheric Radiative Transfer of Sunshine). Thus, we found an average annual increase of 2.04% in the short-circuit current to the monocrystalline silicon module, 2.14% for polycrystalline silicon module and 8.2% for thin film module amorphous silicon; followed by an average annual variation in the conversion efficiency of these photovoltaic modules -1.75%, -1.66% and + 4.19% consecutively. It will be executed sizing with performance conditions under the influence of the standard spectrum (G173-03) and under the particular influence of the spectrum of the Serra Gaúcha region, it was determined which of these technologies has the best features and lower return time of the investment to the specific climatic and geographic conditions of the city of Farroupilha, RS.
