Determination of the Optimal Solar Panel Tilt Angle for Baku and Nakhchivan

Year: 2024

Abstract: Solar energy, which is the most widely used of renewable resources, is more preferred due to its affordable cost and easy installation. In order to obtain the optimum amount of electricity from solar energy, it is very important to place the PV panels at an optimum angle to the sun. In addition, other factors such as avoiding shade, suitable and high quality equipment, avoiding dust and pollution also affect the optimum energy from the sun. In this study for two different regions in Azerbaijan, the determination of the optimum solar panel tilt angle for the selected regions, the maximum radiation values that can be obtained, the amount of energy produced from PV panels and their comparison were analysed. When the obtained values are analysed, the difference between 4.25% (Baku) and 5.6% (Nakhchivan) occurs in PV systems with variable tilt angle 12 times a year (every month) compared to fixed angle systems. In addition, when the PV systems with variable adjustment every month are compared, it is seen that the PV system installed in Nakhchivan is 33.4% more than the PV system installed in Baku. When the PV panel inclination angle is constant throughout the year for both regions, it is concluded that 422.7 MWh/year (or 30%) more electrical energy is obtained from the PV system installed in Nakhchivan than the PV system installed in Baku. According to the results of the study carried out in two different simulation tools for both regions, the positioning of PV systems at varying angles every month is more suitable for system efficiency and performance.
