Abstract
Renewable energy sources have been widely studied lately to reduce global impacts on the environment or even to supply the demand of remote locations. In the present work, were analyzed the potential of cogeneration of a high concentration photovoltaic system (HCPV) by using microchannel heat exchangers (MCHE) in relevant ambient, with different manufacturing material and geometrical designs, for heat recovery. Two flow rates (45 and 60 ml/min) were tested to prove the incidence of this variable in the heat recovery in the solar cell. Were observed that for lower flow rates the thermal recovery efficiency decreases. The results for the analysis of a pair of mono modules, with a straight channel heat exchanger installed, showed that mono modules with passive and active cooling had statistically the same electrical efficiency 9.29% and 9.41%, respectively. However, for the single module with active cooling, there is the recovery energy in the form of heat of 46.84% leading to a more efficient global use, where 56.25% of all available energy in the solar cell is used.
