Advanced Solar Tracking Systems

Detailed overview of innovation with sample startups and prominent university research

What it is

Advanced solar tracking systems adjust the angle of solar panels throughout the day to maximize sunlight capture and energy generation. These systems can significantly increase energy output compared to fixed-tilt systems.

Impact on climate action

Advanced Solar Tracking Systems in Utility Scale Solar PV enhance climate action by optimizing energy generation and increasing solar panel efficiency. By dynamically adjusting panel angles to track the sun’s movement, these innovations maximize energy output, reduce land use, and accelerate the adoption of clean, renewable solar energy, mitigating carbon emissions.


  • Solar Tracking: Solar tracking systems adjust the angle of solar panels throughout the day to follow the sun’s path across the sky. This maximizes sunlight capture and increases energy generation compared to fixed-tilt systems.
  • Sensors and Control Systems: Advanced solar tracking systems use sensors to measure sunlight intensity and direction, and control algorithms to calculate the optimal panel angle. Motors then adjust the panels accordingly.
  • Single-Axis and Dual-Axis Tracking: Single-axis trackers rotate panels on one axis (typically east-west), while dual-axis trackers rotate panels on two axes (east-west and north-south), allowing for even more precise tracking.
