EXPERIMENTAL AND NUMERICAL INVESTIGATION OF PHOTO-VOLTAIC MODULE PERFORMANCE VIA CONTINUOUS AND INTERMITTENT WATER COOLING TECHNIQUES

Experimental and numerical investigation of photovoltaic solar modules (PVSMs) performance via continuous water cooling technique (CCT) and intermittent water cooling techniques (ICT) has been investigated in present work. A New cooling technique had submitted for the (PVSM) as compared to previous works. In addition to analyze the enhancement for (PVSMs) temperature, cooling rate, output power, output energy, fill factor, and electrical efficiency. Experimental data were tabulated of (PVSMs) for both cooling techniques. A mathematical model for (PVSMs) were formulated. MATLAB code has been developed and written to solve mathematical model. Numerical integration of (1/3) Simpson's rule was used to estimate the energy enhancement. The average values of cooling rate for (ICT), and (CCT) were (3.4804 Image and (3.1617 Image respectively, than for non-cooling (PVSM). the enhancement of the output power, fill factor, electrical efficiency for (ICT), and (CCT) were (7.349 %) and (5.587 %), (6.313 %) and (2.630 %), (8.389 %) and (6.826 %) respectively, than for non-cooling (PVSM). The energy enhancement for (ICT) was (6. 308%) for current work. By contrast, there were losses in energy for (CCT). Consequently, According to the obtained results, the enhancement for all parameters mentioned above were the better for (ICT) than for (CCT).
