Hello I'm presenting the project SOLAR TRACKER based on an integrated circuit (TDA2822 amplifier). The SOLAR TRACKER PCB prototype and diagram were designed with sun tracking in mind, which allows the solar panel to charge electricity on sunny days. Is the PCB design and schematic correct?...

I look at your tile designs and some thoughts come to my mind: 1. Unnecessary in the case of such simple tiles, you design the tiles as two-layer. 2. Some of the tracks on the board are duplicated on the top and bottom layers - example in this post . 3. You are unnecessarily switching paths of the same network alternately on the top and bottom layers. Example - connection of photoresistor R2 and resistor R4. 4. Less than optimal arrangement of elements. If the terminals of the MOTOR connector were swapped, it would be possible to avoid crossing the paths on the board and route them on one layer.

I routed the paths differently, is it better in this project?

I understand this is for azimuth tracking. I would also add a second system to track the angle of inclination. I wonder how it will handle the day-night-day transition, but the concept is interesting. Let me know when you run it.

And how can I connect this inclination angle tracking system to the system I designed? You've got it in the video, roughly how it works.

Do you need a controller and a stepper motor power supply for this SOLAR TRACKER?

A stepper motor without the appropriate driver will not work at all. This type of engine, depending on its design, has several coils that need to be properly controlled.

Is the PCB design and schematic correct?

4. Less than optimal arrangement of elements. If the terminals of the "MOTOR" connector were swapped, it would be possible to avoid crossing the paths on the board and route them on one layer.

Topic summary

The discussion revolves around a prototype for a solar tracker project utilizing the TDA2822 integrated circuit. The author seeks feedback on the PCB design and schematic, which is intended to optimize solar panel charging by tracking sunlight. Initial responses highlight issues with the PCB layout, such as unnecessary dual-layer design, duplicated tracks, and suboptimal component arrangement. Suggestions include improving routing to avoid path crossings and considering the addition of an inclination angle tracking system. The conversation also touches on the need for a controller and stepper motor power supply, emphasizing that a stepper motor requires a compatible driver for proper operation.
