Experimental validation of a model for PV systems under partial shading for building integrated applications

•A dedicated experimental setup was built to simulate BIPV shading conditions.•PV models under partial shading conditions are validates against experiments.•The developed simplified PV model reduces computational efforts preserving accuracy.•The effects of partial shading on cells are analysed by means of detailed modelling.•A dynamic thermal model is introduced to predict the cell temperature in BIPV systems.
