Passionate Passivity

Data indicates that the conventional passive tracking system generated 50% of its rated output (approximately 0.5 watts of a possible 1 watt), over a period of seven hours of exposure to controlled artificial light conditions. Throughout the trials, the system demonstrated delayed reaction to the thermal exposure, thus decreasing the opportunities for perpendicular angle alignment. Upon further analysis, it is identified that a lack of dual-axis ability limits movement of the passive photovoltaic tracker, decreasing overall system efficiency. Without an adequate restrictor control, it is difficult for the tracker to be precise. It was also noted within this investigation that previous delays proved to have consequences in the system’s following reactions to the artificial light source.

The system was incapable of fast-reacting action to correct any environmental and random delays that decreased the quality of the tracking. Thus, since the system progressively decreased in performance, data at later stages of the exposure period was significantly different from data at initial times in the same exposure. Utilizing the knowledge obtained from this Phase 1: Conventional Passive Tracking System Testing, the second phase of this project will develop a design for improving upon current flaws mentioned of the conventional passive tracking system.

Data indicates that the conventional passive tracking system generated 50% of its rated output (approximately 0.5 watts of a possible 1 watt), over a period of seven hours of exposure to controlled artificial light conditions.

Upon further analysis, it is identified that a lack of dual-axis ability limits movement of the passive photovoltaic tracker, decreasing overall system efficiency. Without an adequate restrictor control, it is difficult for the tracker to be precise.
