Performance analysis of building integrated photovoltaic (BIPV) for commercial buildings in Urban Area

Abstract

The objective of this work is to carry out a performance analysis of building integrated photovoltaic systems. The proposed system will occupy the majority of the unused space of vertical walls and harness more solar energy that can be used as the back up electrical energy resources for daily usage in urban areas. Here mono-facial solar panel is considered that harnesses energy from the front side of the panel. A special parameter i.e. cloud shadow effect is taken into consideration throughout the study. Results show that, proposed system mounted in the rooftop gives 30% less electrical energy in the cloudy days where as the vertically mounted system can generate 26% less electrical energy. The system is more recommendable for the vertical space than rooftop installation.
