A method for evaluating shading losses involved in a GC-BIPV using real data

Abstract

This paper presents a simplified method for evaluating the energy loss involved in a grid connected building integrated photovoltaic (GC-BIPV) system due to partial shading. The method consists in the comparison of the monthly theoretical curve (for un-shaded PV generator) and real fitted curve (deducted from monitoring data) of the maximum energy produced by the PV generator.
