How To Build an MPPT Solar Charge Controller with Arduino
Julian Ilett has a series of 20 YouTube videos that show you how he built an MPPT solar charge controller with Arduino. Maximum Power Point Tracking (MPPT) is electronic tracking that enables the charge controller to compare the output of the panels to the battery voltage. It then figures out what is the best power that the panel can put out to charge the battery.
What that usually means that it tries to increase the charge on cloudy days (or in the mornings if your panel is not pointed to the sun) so that you can get the most from your panels.

What is nice about this one is that he walks you through "How To" build the graphic display.
