The purpose of this article is to constitute awareness about solar PV panels and investigate the effect of tilt angles on the performance at different latitudes of Turkey where the active solar systems are not widely used. The monthly average global and diffuse solar radiations of the locations were calculated numerically. A two-step screening was carried out for detecting the annual optimum tilt angles. Firstly a search between 0° and 75° with 5° steps, then a deeper analysis between 28° and 40° with 1° steps was employed. Then the monthly and seasonal optimum tilt angles were determined. Monthly and annual energy yield of the PV installations were obtained by using PVSyst 5.0 software. The monthly, seasonally and the yearly optimum tilt angles were detected for each locations. As a result it’s found out that, the yearly optimum tilt angles for Antakya, Elazig and Sinop are 32.1, 34.6 and 37.9 respectively. It is also found that mounting the panels at the monthly average tilt angles increase the energy output of PV systems with the ratios of % 5.2 for Antakya, % 6 for Elazig and % 6.3 for Sinop..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
