TO DO

This will be about selecting the right solar cell.

I assumed I could use the 6 or 7 volt solar cell that I already had, as long as the light was only bright enough to provide an actual voltage of only 2V or 3V. It seems that this assumption is incorrect. But why exactly?

I will include something about MPPT. Every five seconds the AEM10941 Solar Harvesting IC checks the voltage across the SRC and GND pins. You can observe this momentary spike using a voltmeter.
