Design of Photo Diode Sensors for Measuring Solar Light Orientation

Abstract:

In this paper, the photo diode sensors are used to realize the solar light detector for measuring the relative solar orientations. The proposed solar light detector comprises five photo diode sensors which are positioned on the front, back, left, right, and upper sides, respectively, on a cubic structure and cubic light-measuring detector is constructed. Accordingly, the photo sensors located on five facets can detect solar light from various directions and measure the incident solar power. Therefore, the relative solar azimuth and elevation angles can be measured precisely. The experimental results have confirmed the validity of the developed system.
