Working Principle of Photovoltaic Support Systems

Photovoltaic support systems provide stable support for photovoltaic modules through mechanical balance and structural stability design, ensuring efficient solar energy reception and resistance to external forces. Fixed supports utilize stable structures such as triangles to firmly fix the modules and transfer gravity, wind loads (e.g., wind pressure resistance ≥0.6kN/m²), and snow loads (e.g., load-bearing capacity ≥1.4kN/m²) through ground, roof, or wall foundations, ensuring environmental adaptability. Tracking supports use sensors (accuracy ±0.5°) to monitor the sun's position in real time and drive motors (e.g., stepper motors with torque 3N·m) to adjust the module angle. Single-axis tracking can increase power generation by 15-25%, while dual-axis tracking can achieve over 30%, maximizing light energy capture.
