Energy obtained from fossil fuels negatively affects the environment and human health. In order to reduce the negative impact of energy consumption in the world, new precautions have been implemented by the International Renewable Energy Agency. Electricity generation based on solar energy comes first among these precautions. This study was carried out to ensure that the solar panels used in solar energy investments to be made in Kayseri benefit from solar radiation better. In the study, it was aimed to determine the optimum tilt angle with monthly, seasonal and semi-annual performances of the panels. Within the scope of the study, Photovoltaic Geographical Information System (PVGIS) was used to detect solar radiation, and PVGIS and Hottel & Woertz (HW) methods were used to determine the slope angles. As a result of the calculations; It was observed that the angle difference between the PVGIS and HW methods increased up to 10.6° in the summer months, and took the same values in the last four months of the year. In Kayseri, if solar panels are positioned with a different fixed optimum tilt angle each month, a maximum solar irradiance of 1852.3 kWh/m2 has been achieved. According to the solar panel positioned with an annual inclination angle of 29.5°; It has been determined that the yield in panel slope angles, which are changed monthly, seasonally and semi-annually, increased by 4.11%, 3.25% and 2.99% per year, respectively. It has been understood that positioning with the monthly optimum angle of inclination provides a great advantage. When the seasonal and six-month optimum slope angles were compared, it was found that the yield difference was 0.26 percent. The fact that this difference is low has shown that it would be appropriate to position the solar panels by changing the angle of inclination twice a year (six months).
