Hi Guys,
I'm new to this forum, and new to solar tracking, but plan to build something myself.  I've looked at various approaches online, and many use sensors. I have an idea of how to do it, but cannot see any reference to this approach on any websites, so maybe it would not work.  Anyway, I wanted to put it out there and ask for feedback. So the idea is to just adjust the position of the panel to maximize the current going to the battery.  The current can be measured across an inexpensive shunt resistor. The Arduino would turn the control motor in the direction that causes the current to increase, and stop once the current starts to go down. It sounds pretty simple.  Am I missing something?
Feedback most welcome.
Regards,
Gerry.
