Yilmaz et al. proposed and tested a sun sensor for photovoltaic panels, which was composed of two photoresistors placed at 180° and separated by a thin wall, as shown in Fig. 15. This sensor detected the Sun's position based on the light intensity. When the Sun moved, the wall produced a shade in some photoresistors.
The calibration process consisted of installing the sun position sensor on the photovoltaic system and calibrating it perpendicular to the surface of photovoltaic system. The sensor was tested with 50000–70000 lumen. The results revealed that the solar tracking error was of 5° with a maximal FOV of 90°.
This sensor detected the Sun's position based on the light intensity. When the Sun moved, the wall produced a shade in some photoresistors.
