At the center of this innovation are rotating solar panels, also known as sun tracking solar panels.
Rotating solar panels follow the sun's path, boosting energy capture throughout the day. They tilt to catch maximum sunlight, upping power generation by 10% to 25% more than fixed panels. This is thanks to their special tracking systems. How do solar panel rotation mechanisms work? These systems adjust the panels' angle using motors and sensors.
This orientation system is expected to save more than 40% of the total energy of the panels by keeping the panel's face perpendicular to the sun. This percentage is assumed to be lost energy in the fixed panels. A special care should be taken to the design of the grid arrangement of panels in the collecting plant.
This leads to the maximum needed torque to rotate the panel which is equal to 15 N.m while the maximum needed power is 1 Watt which forms 1% of the output of the panel. This calculation shows that it is feasible to rotate the panel using electric motors fed by the output of the panel itself.
As the sun moves across the sky, technology follows its lead. At the center of this innovation are rotating solar panels, also known as sun tracking solar panels. They move with the sun, leading to much higher power generation. In fact, the demand for solar installations went up significantly from 2008 to 2013.
This calculation shows that it is feasible to rotate the panel using electric motors fed by the output of the panel itself. The previous calculation is based on having a symmetric shape of the panel neglecting the friction of the rotational joint and the air drag force.
The active algorithm is a closed-loop tracking mechanism based on the control principle with feedback. A light sensor, which detects sun brightness, acts as the input to the system controller. The acquired values are then analyzed by the microcontroller, which controls the motor motion to orientate the solar panel towards the sun.
