A solar tracking system is a key technology to maximize the output of photovoltaic installations. By allowing solar panels to follow the sun’s path, it improves energy efficiency and shortens the payback period of solar projects.
What is a Solar Tracking System?
A solar tracking system keeps solar panels at the optimal angle to the sun throughout the day. From sunrise to sunset, the modules automatically adjust to remain perpendicular to the sun’s rays, producing significantly more electricity than fixed-tilt systems.
How a Solar Tracking System Works
Using sensors and motors, the system detects the sun’s position and automatically adjusts the modules. Two main types are commonly used:
- Single-axis trackers – Panels rotate from east to west. This simpler and more cost-effective solution already delivers a significant gain in output. (→ See also our guide on ground mounting in agricultural zones).
- Dual-axis trackers – Panels move horizontally and vertically to stay directly aligned with the sun. More complex and costly, but they maximise energy production.
Main Advantages
- Higher energy efficiency: up to 20% more electricity compared to fixed systems
- Greater energy yield: ideal for making the most of limited land or for enhancing low-productivity areas.
- Cost savings: more electricity produced means lower electricity bills and a faster return on investment.
- Contribution to the energy transition: increases the share of renewable energy and reduces carbon footprint.
