“…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.…”

“…A prototype of photovoltaic/thermal system using air or water as a cooling fluid to decrease the temperature of solar cell presented by kern et al in 1978 [1]. Since then considerable research was performed in order to reduce the cost of photovoltaic/thermal systems using new concentrating photovoltaic/thermal configurations [2][3][4][5][6][7]. Most of the effort was devoted to the optimization of the concentrator with a given exchanger geometry.…”

In this paper, a theoretical study of a photovoltaic/thermal air system with a parabolic concentrator is presented. The investigated system consists of a photovoltaic panel under which air is made to flow through an exchange in order to extract heat from the panel, thereby cooling the cells and hence increasing their efficiency. The global energy yield of the system is evaluated in clouding both the electrical output of the modal and the thermal energy of air. The energy balance equations of the whole system are computed using the GAUSS-SAIDEL method, allowing to estimate heat transfer from all the main components, the results show that the daily yield, of the system increases with air mass flow rate, and decreases with the exchanger channel width. results at solar irradiance of 1120 W/m 2 show that the combined PV/TH efficiency is increasing from 60% to 75% and mass flow necessary to maintain the cells temperature constant decreasing form 1.8 to 1.2 Kg/s, at exchanger channel width varies from 0.35 to 0.05 m.

“…In 1978, kern and all [1] presented a prototype of a thermal/photovoltaic system using air and water as a coolant to reduce the temperature of the solar cells. A number of theoretical and experimental studies to assess the efficiency of hybrid thermal/photovoltaic system have been performed [2][3][4][5][6][7]. Florschuetz and all [2] used the model of hotel-Whillier to analyze the performance of the hybrid solar system that could provide domestic hot water.…”

“…Garg and all [3] have developed a stable model to simulate the performance of thermal/photovoltaic hybrid system. In the recent years much research has been reported in the literature on new solar thermal systems with lower costs [4][5][6][7]. When sunlight is concentrated on the solar cell, most of the energy absorbed by the cell is converted into thermal energy which in turn increases the temperature and reduces the electrical efficiency.…”

Hybrid thermal/photovoltaic systems associating a solar concentrator with a heat exchanger are an effective way to improve solar energy conversion yield. We present here an analysis of the effect of the mass flow rates in such a collector. A numerical simulation of the performance of the thermal/photovoltaic sensor with a heat exchanger including fins attached to the absorber and using air as a coolant is presented. A thorough analysis of the influence of the mass flow rate on the efficiency and the working of a thermal/photovoltaic collector is presented. The analysis is made using the equations of the components of heat transfer cascade into a matrix of four unknown's which are the glass , cells, fluid and insulation plate temperature. This matrix is solved by the fixed point method and Gauss-Seidel, at the permanent regime. Results show that the overall conversion efficiency of the system is increasing from 27% to 65%, and the cell temperatures decreasing from 345°K to 335°K when mass flow rates varies from 0.02 kg/s to 0.1 kg/s.
