Passionate Passivity - Observations

In Phase 2: High-Precision Passive Tracking System Development, a new design was proposed and constructed to replace conventional passive photovoltaic panel tracking systems. A small-scale functional model was used for testing under a controlled environment with an artificial light source, utilizing the same test environment as the previous phase’s conventional passive tracking system testing. Throughout the seven-hour exposure period to light radiation, it was noted that the designed system of this project performed much better than the conventional system, producing a greater net output. This was accomplished through a higher level of accuracy for the tracker’s angle to the light source, and a lower angle of deviation.

During the initial time exposures to the artificial light source, the system was not as precise as it was later in the exposure period. This was because it took a considerable amount of time for the entire system to be activated by the thermal energy. Each side had to react individually for increased precision, which took time. However, in comparison to the conventional passive tracking system, the designed passive tracker in this phase maintained improved accuracy throughout the entire exposure period. This is advantageous because the thermal dynamics of the system is not affected by any environmental and random delays that may occur. In general, the hydraulic restrictor control of the system performed its function effectively. It reacted to the movements of the metal thermal expansion processes in order to tilt the panel in a specific manner. Although there were some material limitations to this constructed small-scale design, this project phase demonstrates the potential for this concept in passive photovoltaic panel tracking.
