摘要

The intelligent single-axis solar tracking system enhances energy efficiency by actively and passively tracking the sun, optimizing photovoltaic (PV) output even under partial shading conditions. Research shows that partial shading significantly reduces energy production, and incorporating tracking systems with optimization algorithms can mitigate these effects. The system maximizes energy by adjusting the PV modules’ orientation throughout the day, with active backtracking methods reducing shading impacts. Fluid simulations for wind loads were conducted on the structure, and results showed the system can withstand wind speeds of 15 m/s with a factor of safety. The system also mitigates wind load risks by moving into a safe stow position during high winds, increasing durability. With 12-h autonomy and data logging, it supports real-time performance analysis. Its dismantlable design offers flexibility for transport, making it adaptable to various environments, and an effective solution for maximizing solar energy generation.
