2-E (Energy-Exergy) for partially covered concentrated photovoltaic thermal (PVT) collector

摘要

In present study, the concentrated photovoltaic thermal (PVT) has been proposed for higher thermal gain. The compound parabolic concentrator (CPC) has been also implemented with photovoltaic thermal (PVT) to increase higher input energy or solar radiation to get higher temperature. Here, water and dimethyl-diphenyl silicone fluid (DMDP) have been considered as a fluid for proposed system. The comparative study of two fluids: water and DMDP has been presented. The maximum outlet fluid temperature of PVT (25% of collector area covered by PV module) - CPC collector have been optimized for 190 °C at mass flow rate=0.06 kg/s of this fluid. The area of receiver and aperture are 2 m~2 and 4 m~2. The concentration ratio is 2. The area of semi-transparent (glass to glass) PV module is 0.5 m2. The annual analysis has been carried out for a clear day condition for each month, New Delhi, India. Here, the net annual overall thermal energy and exergy have been found 304.46 kWh and 50.58 kWh, respectively. The electrical gain has also been found as 12.97 kWh. The proposed system has been designed for space heating or drying for many applications with self-sustainability feature.
