A comprehensive method for estimating energy losses due to shading of GC-BIPV systems using monitoring data

In this paper, a comprehensive method for evaluating energy losses of a grid-connected building integrated photovoltaic (GC-BIPV) system due to partial shading is described. The method consists to make a comparison between theoretical and measured (monitoring data) curves of the maximum output energy produced by a GC-BIPV system installed at Jaén University (Spain). The results showed that loss of energy is 1.79 kWh/day, which corresponds to a shading factor of 14.4%.

► Energy loss is 1.79 (kWh/day) which corresponds to a shading factor of 14.4%.
► Proposed method can serves as a tool for the performance analysis of GC-BIPV systems.
► The method validation is carried out by a developed simulation procedure.
