[0002] Photovoltaic panels are devices that convert solar energy into electrical energy. Their basic principle is the photovoltaic effect, which converts energy from sunlight into electricity. With the growth of global energy demand and increasing focus on renewable energy, photovoltaic power generation has become an important clean energy technology.
[0003] The efficiency of photovoltaic (PV) power generation is significantly affected by factors such as geographical location, weather conditions, and seasonal changes. In areas with scarce sunlight, the economic viability and sustainability of PV power generation are poor. Conversely, in areas with abundant sunlight, it is necessary to ensure direct sunlight on the PV panels to improve their power generation efficiency. However, currently, most PV panels can only be fixed in one direction to receive sunlight. Since the sun's position changes throughout the day, fixed PV panels receive limited solar energy, failing to convert it into more electricity and create greater economic value.
