Solar Tracker Project

I've looked at a few MPPT parts on the web and have not seen many items that looked like they would be very easy get working.
Too many small parts add to the complexity and cost.

For a 26AH battery, it seems like a 60W PV panel would be more than power to do the job, using a regular charger circuit.
If that's not enough, I would most likely just buy a cheap Chinese MPPT charge controller.
