Exergoeconomic and Envirnoeconomic Analysis of Building Integrated photovoltaic Thermal (BIPVT) System and its Optimization

Abstract

This paper gives an idea about advantage of semitransparent photovoltaic system over opaque system. In an inclined system. Considering different parameters of the cell, room, duct and tedlar effect has been made to increase the overall efficiency of the total system. Thermal Model has been designed and mathematical analysis has been done. Electrical as well as thermal energy calculation has been compared with other system from different outputs of different places. If we compare a normal PV system definitely the hybrid PVT system has an edge over PV as in PVT system we consider thermal energy too. A soft computing technique has been developed to optimize the exergy of the system by varying the velocity and length of channel. For the proposed system, it has found that air at 4.5 m/s and channel length of 0. 2083 m gives maximum exergy. A total thermal energy gain of 54716kWh and electrical energy gain of 15838kwh is obtained.
