Simulation of a Building Integrated Solar PVT- Roof System

摘要

The present photovoltaic solar cell (PV) converts solar energy into electricity with efficiency, of less than 20%. Photovoltaic thermal (PV/T) system consists of PV module along a heat removing passage to remove the heat below the PV. Also PV/T systems can provide simultaneously electricity and heat, and hence can serve dual purpose. In this paper comparative study of three roof models are discussed -1) Conventional roof: Conventional roof is taken as a base case which is made up of concrete.2) roof with photovoltaic, 3) roof with photovoltaic thermal (PV/T). The electricity consumption for each system is computed using EQUEST software. Also estimation of carbon di-oxide emission is compared in each case done for each system.
