This study provides estimates of photovoltaic (PV) panel optimal tilt angles for all countries worldwide. It then estimates the incident solar radiation normal to either tracked or optimally tilted panels relative to horizontal panels globally. Optimal tilts are derived from the National Renewable Energy Laboratory's PVWatts program.
The optimal tilt angle is calculated by adding 15 degrees to your latitude in winter and subtracting 15 degrees from your latitude in summer. For example, if your latitude is 34°, the optimal tilt angle for your solar panels in winter would be 34 + 15 = 49°. For precise data tailored to your specific situation, use our PVGIS solar calculator.
The PV panel performance to generate electrical energy depends on many factors among which tilt angle is also a crucial one. Among hundreds of research work performed pertinent to solar PV panels performance, this work critically reviews the role of tilt angles and particularly locating the optimum tilt angle using different methods.
Moltames and FarajiMohammad calculated the optimal monthly, seasonal, semi-annual, and annual tilt angles of solar panels in different cities of Iran. The results show that the optimal tilt angle for each city is approximately 4–8° lower than that city's latitude.
