Determination of the optimum tilt angle for photovoltaic panels in Diyarbakir city

With the discovery of solar energy production of PV panels, humanity started to show great interest in this field in electricity generation. While entering the atmosphere of the earth, the sunlight emitted from the sun source comes to the earth at various angles. Here are some angular values of the sun; azimuth angle, zenith angle and tilt angle can be calculated. In this study, the experimental study was completed by calculating the optimum inclination angle of the PV panels for Diyarbakir city and making use of solar energy with maximum efficiency. Necessary calculations are made with the help of the sun's declination angle (δ), hour angle (ω), time equation and azimuth angle (γ). As a result of these calculations, the optimum inclination angle and the current and voltage values of 3 panels, 10 degrees below and above this angle, are measured. The power calculation was made in line with the DC voltage produced by 3 PV panels with different inclination angles and the DC current values from which various loads are fed. The accuracy of the optimum angle is ensured by comparing the voltage current values produced by the panel with the optimum inclination angle and the PV panel in the same physical conditions and conditions but with different inclination angles.
