Passionate Passivity - Observations

In this investigation, a conventional passive photovoltaic panel tracking system, constructed from small-scale materials and an adapted version of the partial pressure vapourization system, was tested under a seven-hour exposure period of an artificial light source environment. According to qualitative observations at the initial stage of the testing, the system performed fairly accurately with a high angle to the light source, high voltage output, and a low deviation angle. However, the conventional passive tracking system decreased progressively in accuracy, due to the overall slow reaction of the system. This resulted in a higher deviation angle and a lower angle to the light source. This disadvantage can be attributed to the partial pressure vapourization system, which used a chemical process for mechanical purposes. With a higher environmental temperature controlled throughout the investigation, the progressive decline in performance greatly affected the net power output of the system, decreasing voltage.

The small-scale construction of the conventional passive tracking system was an accurate representation of the actual tracker. It demonstrated many of the major flaws that exist within today’s passive tracking systems, and confirms present research that has been conducted into this field regarding the economic and mechanical practicality of the system. Thus, improvements to conventional systems will be discussed further in this project.
