| Abstract | ||
| The experiments have been carried out to compares the effects of surface cooling by a thin continuous film of tap water, distilled water and nanofluid (distilled water and chicory nanoparticles). The nanoparticles mixed with distilled water with various concentrations of nanofluids such as 0.01%, 0.03% and 0.05% running on the front of the PV module to investigate the performance of photovoltaic solar system. Data obtained from the elemental composition analysis of green chicory revealed the presence of 23 elements with nano size. The formation of potassium chloride nanoparticles was confirmed by X-Ray Diffraction, XRD, with average crystallite size 20 nm, which is in agreement with Transmission Electron Microscpe, TEM, analysis Scanning Electron Microscope, SEM, analysis shows the aspheric potassium chloride and other minerals nanoparticles [1]. It was found that Nanofluid has more effect on improving the panel performance than pure water. The average output power of the PV module increased from 3.83% to 7.95% with increasing the cooling flow rate of tap water from 0.275 to 0.85 L/min and distilled water from 5.67% to 7.94% with flow rate of 0.75 to 0.85 L/min compared without cooling. But for nanofluid of 0.95 L/min with concentration of 0.01, 0.03, 0.05% nanoparticles, the average output power were increased from 8.023% to 8.816% by about 10%. The average improvements of daily back surface temperature of PV is found about 30% at cases of distilled water with flow rate of 0.95 L/min and nanofluid with concentration of 0.05%. | ||
