Effect of the angle of solar irradiance on the photo generation of a photovoltaic module

The correct installation of a photovoltaic system is vital to obtain the expected generation when sizing the energy that will be needed, since photovoltaic technology is constantly exposed to factors that can reduce its efficiency. In this work, the effect of the angle of solar incidence on the surface of a module was analyzed, through the comparison of the power generated at different angles of inclination from 10 to 45°, and giving the module different angles of orientation from east to west passing through the south (90° to -90° in the azimuth). The behavior of irradiance over time was also analyzed. Derived from this study, it was found that, for the city of Torreon, Coahuila, Mexico photovoltaic modules should be installed facing south and with an inclination of 25°, in addition, the region has an average HSP of 6 hours that occur around noon
