How to use a circuit diagram template.
- 01Choose your tracking method
Decide between single-axis (east-west) and dual-axis (plus elevation) based on your project needs.
- 02Place the light sensors
Position two LDRs or photodiodes with a divider so the controller can compare light intensity.
- 03Add the controller and motor driver
Connect the sensor outputs to an Arduino or PLC, and route control signals through a motor driver or relay.
- 04Connect the motor or actuator
Wire the motor that adjusts panel position, ensuring polarity and limit switches are included for safety.
- 05Label and verify the circuit
Annotate all connections, power rails, and ground, then simulate if possible before building.
Questions about circuit diagram templates
What components are needed for a solar tracker circuit?
A basic circuit includes two light-dependent resistors (LDRs), a microcontroller like Arduino, a motor driver, and a DC gear motor. Dual-axis versions add a second motor and sensor pair.
Can I use a PLC instead of Arduino?
Yes, PLCs are common in industrial solar trackers. The circuit diagram will show digital inputs from sensors and outputs to motor contactors or relays.
How does a dual-axis solar tracker differ from single-axis?
Dual-axis tracks both azimuth and elevation, requiring two motors and additional sensor pairs; single-axis only follows the sun east to west.
Is it possible to simulate the circuit before building?
Yes, you can use our online tool to draw and check the connections logically before wiring hardware, reducing errors.
What software can I use to design a solar tracker circuit?
Our circuit diagram generator is designed for this purpose, with ready-made symbols for sensors, controllers, and motors to speed up your work.
