Photovoltaic panel servo principle

How servo motors are used in solar PV system?

In this work, tiny servo motors controlled directly by the microcontroller are used to moving the PV panel with very low energy consumption. On the other part, in a large solar PV system, the required structure will be much heavier and will require powerful motors and the power requirements will be higher.

Why do we use servo motors for PV panel motorization?

Moreover, we used servo motors for the motorization of the PV panel instead of stepper motors or DC motors as in 50, 56, 55 that need an interface circuit to control the speed and the position, which increases the materials and the consumption of the energy.

What is a servo motor in a solar tracker?

A servo motor (SG90) for the solar tracker's vertical movement and a micro servo motor (MG996R) for the horizontal movement. A servo motor is able to wait for predetermined positions in the instructions given to it and then to maintain them, so it works in a closed loop.

How does the servo motor work?

The servo motor moves the solar panel towards the direction of higher light intensity. The movement continues until both LDRs detect almost equal light levels. Continuous Tracking: The system continuously monitors and adjusts throughout the day. At sunset, the system can be programmed to return the panel to its original position for the next day.
