Have you ever noticed how solar panels are positioned to catch the most sunlight? That’s where solar trackers come in!
A solar tracker automatically adjusts the angle of solar panels so they always face the sun. This helps them absorb more sunlight by reducing reflection, which means they generate more energy.
Simply put, the more direct the sunlight, the more power a solar panel can produce. That’s why solar trackers are commonly used to keep panels aligned for maximum efficiency!
What Is Solar Panel Tracking?
Solar tracking technology offers a significant advancement in photovoltaic (PV) panel orientation. While traditional fixed-mount systems suffer from suboptimal energy yields due to their static positioning, solar trackers dynamically adjust panel angles to continuously follow the sun’s trajectory.
By maintaining and using solar panel cleaning robots throughout the day, solar trackers reduce energy losses from improper alignment, enhance light absorption, and ultimately maximize the efficiency of PV systems. This technology represents a key innovation in solar energy optimization.
Components Of A Solar Tracker-
A solar tracking system consists of several critical components that facilitate continuous alignment with the sun:
(1): Tracker Mount – The structural framework that supports and positions the photovoltaic panel at the correct inclination.
(2): Driver – A control mechanism responsible for regulating the rotation of the motor shaft.
(3): Sensors – These detect solar-induced parameters to provide real-time data for precise tracker adjustments.
(4): Motor – The actuator responsible for executing tracker movements.
(5): Algorithm – A computational model that determines the sun’s position based on time, date, and geographical coordinates to optimize panel orientation. Further, read Solar Trackers Boost Power Generation Efficiency.
Types Of Solar Tracking Systems
- Passive Trackers – Move when sunlight heats a special gas inside them.
- Active Trackers – Use motors and sensors to move the panels.
- Open Loop Trackers – Move based on a set schedule.
- Timed Trackers – Change direction at certain times of the day.
- Altitude/Azimuth Trackers – Move based on the sun’s height in the sky.
How Do They Move?
- Single-Axis Trackers – Move in one direction to follow the sun.
- Dual-Axis Trackers – Move in two directions to catch the most sunlight all day long!
Smart Solar Tracking
- Active Trackers use motors to follow the sun.
- Passive Trackers move when heat changes the pressure inside them.
Is A Solar Tracking System Good To Be Used?
The installation of a solar tracking system from a solar tracker manufacturer is contingent on site-specific factors, including solar energy availability, climate conditions, and spatial constraints. These systems enhance power generation in both ground-mounted and roof-mounted PV installations, provided there is sufficient solar exposure.
While solar trackers significantly improve energy yield, they may not be suitable for all installations. Considerations such as terrain, shading, structural feasibility, and regional weather patterns should be evaluated before implementation.
Solar trackers are particularly advantageous for locations with limited space and high energy demands. Additionally, they offer substantial benefits in high-latitude regions, where seasonal variations in solar angle impact energy capture.
