Performance analysis of a double-pass photovoltaic/thermal (PV/T) solar collector with CPC and fins

Effect of Air Channel Depth and Mass Flow Rate on the Efficiency of Hybrid Thermal - Photovoltaic Sensor

“…Fins are fixed on the heat exchanger to improve heat transfer from the solar cells to the fluid. The heat exchanger bottom is covered with a good insulator to minimize heat losses to the ambient [7].The cold air enters the exchanger through a centrifugal compressor; the latter is powered by an alternating current. The controller convert a power generating part continues by alternative power cells so that the compressor works.…”

“…Garg and all have developed a stable model to simulate the performance of thermal-photovoltaic hybrid system [3]. In the recent years much research has been reported in the literature on new solar thermal systems with lower costs [4][5][6][7]. In this work we analyze the mass flow rate and the exchanger channel depth effects on the efficiency of the system when the length of the system, the cell parameters (V, I, T…..) and the cooling by the exchanger vary.…”

Photovoltaic Systems and Applications

“…www.intechopen.com The use of a CPC with a double-pass PV/T air heater was examined by Othman et al (2005). In the considered design, the bottom surface of the absorber has vertical fins (Fig.…”

Performance of a V-trough photovoltaic/thermal concentrator

“…They found that their collector for air heating, with a concentration ratio of 3, resulted in better efficiencies when integrated into a system. A similar system was also demonstrated by Othman et al (2005). However, where Garg and Adhikari used a single pass to heat air, they utilised a double pass with a rear finned surface in their system.…”
