This solar tracker system uses the Arduino UNO board, a servomotor, 2 LDRs and 2 resistors to rotate the solar panel towards the Sun or a source of light.

Mysoltrk solar panel Sun tracker Mysoltrk operates using a set of two straightforward, yet sturdy actuators, each one constructed around a 6V 30RPM geared DC motor.

Solar trackers can improve the energy harvesting ability of a solar panel by a substantial margin, and now [Jay] has a two-axis tracker that is also portable.

An Arduino Nano was chosen as it was low power, low cost, and easy to modify. A L298N h-bridge drives the motors, and a shunt is used instead of limit switches to reduce costs further.

Dual-axis solar tracker based on UV, MEMS sensors Researchers have designed a new tracking system that utilizes an arithmetic optimization-based PID controller.
