Solar Tracker

The solar tracker works by using two photoreceptors on each axis of motion. These sensors capture solar radiation, so a difference between them on the same straight line will indicate that the sun is not located perpendicularly.

As shown in the diagram, the intensity of the solar radiation captured by the sensors is not the same, slewing drive since the sun is not perpendicular to them.

By means of an electronic control system, this difference is translated into movements of the motors that regulate the position of the solar tracker.

When the solar intensity captured by both sensors is practically the same, the motors will stop and the solar tracker will be positioned in such a way that the sun will strike perpendicularly on them.

In the following diagram, you can see the mechanical operation of the solar tracker.

This design allows tilting and slewing drive azimuth movements, which allows the solar panel to be positioned optimally.

A Sensors
B Solar panel  
C Gears for inclination movement
D inclination motor  
E Crown for azimuth movement
F Azimuth motor
