Optimization of the Tilt Angle of Solar Panels for Seven Cities in Türkiye

Abstract Türkiye occupies a crucial position in harnessing solar energy due to its solar radiation and duration of exposure to the sun. To maximize energy yield from solar power, photovoltaic panels must be inclined at an optimum angle relative to the sun’s position. This study employs the photovoltaic geographical information system program to determine monthly, seasonal, and annual optimum panel tilt angles for seven selected cities in Türkiye. By utilizing this data, adjustments can be made to the panel tilt angle to optimize energy production. This research contributes to advancing solar energy utilization in Türkiye and similar regions, facilitating sustainable energy generation. The results indicate that adjusting the panel tilt angle seasonally and monthly is more profitable compared to using the same panel tilt angle throughout the year. This profitability increases to 4.20% with seasonal adjustments and can reach up to 5.05% with monthly adjustments. While the seasonal and monthly adjustments of panel tilt angles have the most significant impact on Bartın, they have the most negligible impact on Kastamonu. These findings underscore the importance of location and tilt angle selection when establishing solar energy facilities to assess Türkiye’s and neighboring countries’ solar energy potential.
