Model for electric power estimation in photovoltaic silicon modules

Abstract

The photovoltaic modules have a power generation capacity dependent on the location site’s weather
conditions. This work develops and evaluates a model that determines the power generated by solar
modules based on monocrystalline, polycrystalline and an amorphous thin silicon film, if the temperature
and irradiance conditions of the zone in which they are planned to be located are known. The model was
carried out by analyzing the solar modules potential response to the climatological behavior, during a
year, Measures collected by a meteorological system; the model parameters were calculated applying
the quasi-Newton with BFGS update algorithm. The power model response was compared to the real
photovoltaic generation system that includes the three technologies and a D.C. load, evidencing that the
real response corresponds to the estimation delivered by the model.
