An analysis of BIPVT system has been carried out in this paper based on arrays named as solar cell tile array and semi-transparent array. 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.
