| Summary: | ABSTRACT The contribution of photovoltaic energy has steadily increased within the energy matrix worldwide. Within this renewable energy system, optimization is there is continually pursued, which can be achieved through various approaches, including advancements in photovoltaic cell technology, impedance adjustments, inverter efficiency, collected energy storage (either on- or off-grid), cell cooling, module cleaning, and solar position tracking, which was the focus of this study. In remote areas without electrical grid access, motorized systems may not be feasible. A tracking prototype was developed whose structure is classified as chronological due to its fixed rotation, manual as it requires daily adjustment, single-axis azimuthal, and "analog" as it lacks motors, sensors, or algorithms. The results showed that the developed tracking prototype achieved a 9.69% energy production increase during the research period, with peaks of 35.51% on sunny days, and a significant efficiency improvement during the early morning and late afternoon. Statistical analysis results revealed a significant energy production difference between panels. In terms of economy, the prototype proved unviable when compared to the cost of grid electricity. |
