Project Summary |
|||||
Conventional passive photovoltaic panel tracking systems are ineffective for collecting solar radiation due to their imprecision as a result of slow reaction to thermal exposure and lack of dual-axis flexibility for seasonal change. Passive trackers use chlorofluorocarbon and hydrochlorofluorocarbon vapourization processes, which are environmentally hazardous. Dual-axis active tracking systems are more efficient due to their speed and precision from electrical motorization. However, active tracking systems are not cost-effective, requiring constant mechanical realignment. This project aims to develop a high-precision and fast-reactive passive tracking system that will optimize perpendicular tracking through the methods of thermal expansion, hydraulic restrictor control and dual-axis flexibility. A study is first conducted on the conventional passive tracking system’s angle alignment accuracy, net energy output, and efficiency. Results indicate the conventional system generated only 50% of its rated output, on average, over an exposure period of seven hours. This project proposes an innovative passive photovoltaic panel tracking system, the first with high-precision ability, dual-axis capability, as well as an environmentally-positive mechanical hydraulic restrictor control. Under the same test conditions, the designed system optimizes energy collection during all exposure periods, matching conventional active tracking in virtually 100% efficiency according to the rated output, while eliminating most maintenance costs due to its higher reaction speed. In net output comparisons to the standard passive tracker, this design generates 96% more energy, as it fully achieves angle alignment accuracy. This design can be used to power third world countries and geographic locations with warmer climates. |
