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.
