This paper describes the design of a low cost solar tracking photo-voltaic (PV) array system as part of an undergraduate senior project. The solar tracking system is interfaced with a solar panel, a mechanical driving mechanism, a signal amplifier and an analog to digital converter (ADC). Solar tracking is realized through ”field” programming using Lab View programming language on a lap-top computer and alternatively with a low cost solar radiation sensing transducer consisting of an array of photoresistors (CdS cells). Actuation of the panel tilt for azimuth tracking and rotation of the panel for solar tracking are operated with a gear motor-based control system for adjusting the PV mount system's position so as to collect maximum solar radiation. The gear motor controller module is built with state-of-the-art low-cost digital logic circuit with built-in flexibility to accommodate seasonal position adjustments of the PV mounts. The design includes a computer access for monitoring the power generation of the system. The system is configured for a solar radiation condition specific to the location of the system at the Chinese Culture University of the Shilin District in Yang Ming Shan, but could be easily configured for any other locations.
