A solar tracking controller is a control device used to drive a solar tracking system. It automatically adjusts the angle of solar panels based on the real-time position of the sun, ensuring that photovoltaic panels are always aligned at the optimal angle to the sun, thereby improving photovoltaic power generation efficiency.

Compared to fixed solar panels, photovoltaic systems equipped with tracking controllers can increase power generation by 10% to 35%, with the advantage being more pronounced during early mornings, evenings, or in winter when sunlight is weaker.

A solar tracking controller uses built-in sensors, clock chips, or algorithms to calculate the sun’s position in real time and control the motor to rotate the mounting bracket.

Common control methods include:

1. Light-sensing: Uses light-sensitive sensors to detect light intensity and automatically adjust the angle.
2. Astronomical algorithm: Calculates the sun’s trajectory based on geographical coordinates, time, and date to achieve precise tracking.
3. Hybrid control: Combines light sensing and astronomical algorithms to ensure high-precision tracking around the clock.

Advantages of solar tracking controllers

Enhanced power generation efficiency: Maximises the utilisation of solar radiation.

Intelligent management: Supports automatic detection, fault alerts, and remote monitoring.

Extended equipment lifespan: Intelligent regulation prevents mechanical overuse.

Flexible compatibility: Applicable to single-axis and dual-axis photovoltaic tracking systems.

Application scenarios

Large-scale photovoltaic power plants: Enhances overall power generation and reduces the cost per kilowatt-hour through tracking controllers.

Distributed photovoltaic systems: Suitable for industrial buildings and agricultural photovoltaic projects.

Off-grid power generation systems: Improve energy acquisition efficiency for independent power systems.

How to Select a Solar Tracking Controller?

1. Compatible tracking type: Confirm whether it is a single-axis or dual-axis tracking system.
2. Control accuracy: Higher accuracy results in greater power generation gains.
3. Weather resistance and stability: Must withstand high temperatures, extreme cold, and sandstorms.
4. Intelligent features: Does it support remote monitoring, data logging, and communication interfaces?
