What the original version of this project would be very good at is keeping a solar panel always pointing in the right direction. The greater solar efficiency would soon pay for the hardware.

The economic benefits of solar tracking in photo voltaic installations are not always positive, see e.g. https://www.sciencedirect.com/science/article/pii/S1876610214030471

I guess as one moves away from the equator the potential benefits of tracking increases though.

yes, its questionable if you are talking about an array of panels where tracking panels need be far enough apart to avoid shadowing each other.  My interest is in the case of one panel. Two situations -

1. Campers - right now, to get max sun, we need to pop back to camp and move the panel. Camping right now and moving that panel when I remember.

2. My wife recently sold an "Off grid" home that used a large-ish frame containing 9 or 12 (??) smaller panels. The frame itself rotated to track the sun and provided most of the house's electrical needs. (The tracking mechanism had failed long before I appeared on the scene)

In both cases, the reduced cost of solar panels weakens my arguments !

I'm asking here because I'm completely curious because I want to get the opinions of the masters on the subject.

Using pascal , is it possible to create such a head tracking application with already existing packages ?
If Ide=Lazarus 2.0.10 32 Bit and Os=Win 10 Home 64 Bit then Get up and do something useful! Because God is the helper of those who start again;

A good video is here https://www.youtube.com/watch?v=Q9Av10UxBEI you see - it is possible. But the question is - the soloution is finished with arduino. Why should you start it with pascal. Or is the way the target :-)

Thank you very much af0815 for the reply. Yes your video is better for start

I'm very inexperienced on this subject, it doesn't matter as a solution, pascal or someone else, I'm grateful for any information you provide.

Instead of the APDS9960 gesture sensor used in the video af0815 linked to, one could also use an IMU such as the mpu6050.  Incidentally I have a Pascal library for this sensor, so it would be a simple matter to convert the measured angles to servo equivalent output.

Thank you very much ccrause for the information. Awesome, you have a lot of ores. I note these links.
I'll hopefully get a start soon. (In useful works, there are many obstacles)  :)

Nice project, I hope we will work together in the future.

Apropos sensors, I've just been watching this which is interesting... I didn't realise low-end LIDAR was so accessible.
