Simple Solar Tracking Sensor Is Self-Powered

Focus:

The solar tracking sensor plays a very important role in photovoltaic systems where it increases the overall system efficiency by directing the solar panels toward the sun. Using the signals obtained from the solar tracking sensor, a control loop rotates the panels toward the sun. This article presents a simple, reliable and cost effective sensor circuit design that is also self-powered. The circuit consists of photodetectors and an SLG88103 operational amplifier. The photodetectors, which sense the solar radiation, also power the op amp. Circuit operation is analyzed, and simulated results and an example implementation are presented.
