Previously comparisons and performance analysis were carried out for opaque and semitransparent system in non-optimized way but in the present case it has been optimized to get better results. As far as energy efficiency and exergy is concerned semitransparent PVT has an edge as compared to others in all respect. Semitransparent PVT has higher useful energy gain by 2.5 KWH as compared to SCT. Further the electrical and thermal efficiency has been derived and a conclusion has been made that semitransparent PV cell has an edge in all respects as compared to SCT. The electrical efficiency has been increased to 17.17% from the previous 16% and overall exergy to 18.4% from previous 17.1%. i.e. an overall growth of 6.8% and 7.6% respectively.

Introduction In recent times solar thermal systems are widely used, but PVTs are not used extensively. More than 80% of the incoming solar energy is either reflected or absorbed as heat energy. Loferski et al. (1998) studied and obtained few results related to the system with air circulation in a housing. Agrawal and Tiwari (2009) concluded that in terms of energy saving glazed hybrid gives better result as compared to normal PV module. Vats and Tiwari (2012) provided various data of the efficiency of different types of material out of which one can select. He et al. (2006) used the Hybrid Photovoltaic and Thermal (PVT) collector technology using water as the coolant as a solution for improving the energy performance. The BIPVT system designed by (Agrawal and Tiwari, 2010) have shown that the roof top placed in an effective area of 65 m 2 , is capable of producing the net electrical and thermal exercise of 16,300 kWh and 1550 kWh, respectively, at an overall thermal efficiency of 54.2%. Kim and Kim (2012) have studied simulation of air-type building-integrated photovoltaic-thermal system. Singh et al. (2015) described the modeling and optimization of single channel system by genetic algorithm. The scheme proposed by Singh et al. (2016) made a comparative study of exergy of different cities and concluded that there is an increment of 5.8 to
