Though the solar photovoltaic (PV) module is used for power production, it usually works at high temperatures, decreasing its efficiency and therefore its output. So if an effective cooling method is to be implemented, it would reduce the heat from the solar PV module and increase its power production. Significant research in water cooling on both top and bottom surfaces of the PV module widen the scope for uniform cooling with constant module temperature throughout at any instant. In this work, uniform flow is maintained by means of overflow water from a tank fitted on the top of the PV module. Experiments were carried out with and without cooling. Performance parameters in terms of power output and efficiency have been presented for the PV module without cooling and cooling with three different mass flow rates. The results show that there is a significant rise in efficiency of the PV module by reducing its temperature. An accelerated output power of 23 W has been observed for a higher mass flow rate of 5.3 kg/min which is 15% higher than the photovoltaic module operating without cooling. Results were compared with previous researchers’ work and found to be a good enhancement. Theoretical results agree well with experiments.

“…42 Therefore, in order to achieve high energy efficiency, it is necessary to investigate possible to cool down solar panels' temperature and resulted in an efficiency increase of 12% [9]. Both 49 Bahaidarah [10] and Nizetic et al [11] The schematic of the experimental system is shown in Figure 1. Voltage (V) in Figure 5, it can be seen both current and voltage had significant increase under cooled condition.…”

“…In early days, the jet impingement heat transfer was thought as one of the better options for achieving a high heat transfer because of their high heat transfer coefficient in the impingement region. A great deal of research [4][5][6][7][8][9][10][11][12] has been devoted on jet impingement heat transfer investigating the effects of different parameters on heat transfer. However, the jet impingement method, in the context of miniaturization, may not be suitable to cool a substrate for high heat transfer applications.…”

In this paper, the fluid flow and heat transfer characteristics of a small rectangular channel fitted with triangular protrusions have been studied in a three-dimensional computational domain. A hybrid cooling strategy employing forced convection air stream with jet impingement on the protruded surface has been numerically studied by solving the conservation equations for mass, momentum, energy as well as turbulent kinetic energy and its dissipation rate in the frame work of finite volume method. The duct and nozzle Reynolds numbers and Prandtl number are varied in the range of 17; 827 Re Dh;duct 53; 480, 5; 135 Re Dh;nz 12; 044 and 0:7 Pr 12, respectively. The effects of the duct Reynolds number, nozzle Reynolds number and Prandtl number on heat transfer rate have been quantified. Extensive numerical computation has also been executed to collect the data for Nusselt number by varying each of the independent parameters. A non-linear regression analysis based on Lvenberg-Marquardt (L-M) method has been used to fit a correlation for Nusselt number utilizing the data captured from CFD analysis. adhana(0123456789().,-volV)FT3 ](0123456789().,-volV)
