(2) 12V Solar Panels....Series or Parallel?
I have (2) 140w 12V panels. The Bogart Engineering solar controller can operate on 12V or 24V input. Is there any advantage or disadvantage to wiring the panels in series for 24V rather than parallel ...

As I read and learn more, it appears the input AND output need to be either 12V or 24V........
So, if 24V, how do you utilize this in our 12V systems?
1) Yes. That's the problem with any PWM - voltage in and voltage out is the same, minus tapering.
2) You can't. This can be done with MPPT controller. Forget about series with PWM.
