Abstract

In this research paper the energy, exergy and power generation of building integrated semitransparent photovoltaic (BISPV) modules for roof and facade has been evaluated. Solar radiation intensity on BISPV modules surfaces is an essential parameter for assessing energy and exergy. The experimental setup consists of two BISPV modules, each of 75W rating, which has been conducted on a clear sky day at roof and façade of Energy Centre building, MANIT Bhopal, India. It is observed that the energy efficiency varies between 11-18% at roof and 13-18% at facade throughout the day. The maximum value of electrical efficiency of BISPV module is 85% at roof and 72% at façade.

5. Conclusion

In this experimentation, a comprehensive analysis of energy and exergy analyses has been carried out to investigate the performance of BISPV module. The experimentation data obtained through measurements during a clear day is analysed to find the optimum temperature, which leads to maximum exergy efficiency. On the basis of practical results the following conclusions have been drawn: It has been found that the building integrated semitransparent photovoltaic module temperature has a great effect on the exergy efficiency. The exergy efficiency of a BISPV module can be improved if the heat can be removed from the BISPV module surface. There are some experimental methods for the cooling of BISPV module using flowing water on the top surface of modules. The design parameters such as BISPV module area have very little effect on the exergy efficiency. As the environmental temperature i.e. ambient temperature increases, the exergy efficiency of BISPV module falls down. The exergy efficiency of BISPV module decreases as the ambient temperature increase due to increasing module temperature. The exergy efficiency of BISPV module increases initially with increase in solar intensity and then decreases after attaining peak point. Future studies should focus on modeling the efficiency of the BISPV module and exergy analysis with destruction.
