As global energy demand increases and environmental standards become more stringent, improving PV conversion efficiency is essential for the widespread adoption of solar power. One of the most critical factors affecting this efficiency is the angle of solar incidence. Solar tracking systems dynamically adjust the orientation of PV modules to optimize solar energy capture per unit area, making them an effective technology for enhancing energy yield. But is a solar tracking system the right fit for your PV project?

Solar tracking systems are primarily classified by their automatic tracking movement into two main categories:

1.Single axis solar tracking system

Single axis solar tracking system rotate the PV modules along a single axis—usually oriented east to west. They offer a compact structure and require less space, making them suitable for installations with limited area. Compared to fixed installations, Single axis solar tracking system can boost power generation by 15%–30%, striking a balance between simplicity and efficiency.

Single-axis trackers can be further divided into two subtypes:

• Horizontal Single-Axis Trackers (HSAT):

These rotate around a horizontal axis typically oriented north-south. The PV arrays rotate east-west around this axis to maintain an optimal angle with the sunlight throughout the day. This design is particularly suitable for areas with low latitudes.

• Tilted Single-Axis Trackers (TSAT):

These use a tilted axis oriented north-south, allowing for better adaptation to variations in solar elevation angles in mid- to high-latitude regions. The system usually employs a three-point mechanical support structure to ensure stability.

2. Dual-Axis Solar Tracking Systems
Dual-axis solar tracking systems allow PV modules to rotate in both north-south and east-west directions, achieving full-scope solar tracking. Research shows that under identical conditions, dual-axis solar tracking systems can increase energy output by 25%–40% compared to fixed installations. This setup is especially beneficial for enterprises with limited roof space, as it significantly increases energy generation per unit area.

Regardless of the type—single-axis or dual-axis—solar trackers must meet strict standards for support strength and load capacity. Materials must be weather-resistant, corrosion-proof, and rust-resistant, while also complying with waterproofing, fire resistance, and high-temperature tolerance standards. Only with these safeguards can a tracking system maintain long-term precision and performance over its 25-year lifespan.

Solar tracking systems, with their unique technological advantages, play a vital role in boosting the photoelectric conversion efficiency of PV modules. To learn more about PV mounting system solutions, follow Huge Energy!
