This research focuses on developing a method of evaluation the effect concentrator solar panel performance to get higher power and optimum efficiency. Also temperature system with without was studied. A Flat Mirror has been used as Concentrator (FMC) for low cost control consumption which fixed module. FMC increase incident irradiance by concentrating sun light ray it then improve cell performance. comparison is made between two PV systems concentrator. The consists flat mirrors glass,...
In this work, we have synthesized ZnO:Al thin films by pulsed laser deposition technique and investigated their microstructural optical properties. The XRD study confirmed a polycrystalline structure of wurtzite ZnO in all films. Further, Al doping has improved the crystallinity decreased crystal size volume unit cell. surface morphology was homogeneous with nanoscopic crystals clustered to form granular nanoparticles. properties significantly increasing concentration. produced are excellent...
Turbulent effects are very complicated and still not entirely understood. Light waves from an astronomical object distorted as they pass through the atmosphere. The refractive index fluctuations in turbulent atmosphere induce optical path difference (OPD) between different parts of wavefront, wavefronts produce low-quality images degrade image beyond diffraction limit. In this paper degradation due to 2-D Gaussian atmospheric turbulence is considered terms point spread function (PSF), Strehl...
People have tended for investing the sources of renewable energy, especially solar as they are clean and environmentally friendly sources. The present work aims to invest measured data irradiance, maximum ambient temperatures wind speed provided by Al Khidhir Meteorological Station predict minimum performance photovoltaic systems (NT-R0E3E-SHARP) electric power generation. single diode model is used calculate output produced module its conversion efficiency based on soalr throughout 2020....
In this research, a general equation was derived to represent the modulation transfer function (MTF) of human eye with presence contact lenses (CL) and during vision monochrome or multi-wavelength (polychromatic) light. This used fit MTF's curves for pupil diameters (EPD) (2.5, 4, 6, 8 mm). The fitting accuracy revealed by using standard deviation (STD). results indicated that image MTF is sensitive (EPD). Moreover, degrades as increases due increased spherical chromatic aberrations. new...
Strehl-Ratio is one of the important Image quality assessment parameters, especially when optical system has some aberrations. The effect pupil shapes on resolution an was evaluated. These systems are apodized with Hanning amplitude filter under influence coma aberration. analytically computed results illustrated graphically in terms point spread function curves various considerations aberrations and a different degree apodization. This study shows that square aperture half diagonal (1) high...
During the day, ground usually becomes hot because of solar radiation. The lowest atmospheric layer absorbs heat from ground, expands, and rises, producing worst turbulence atmosphere refractive change. This index along path will produce an aberration in image object destroy quality at plane. slant is more complicated than horizontal direction need numerical methods to calculate it. In this work, for different was studied. effects angle observation (Zenith Z0=0, 5, 50, 60, 70, 80, 90...
