Solar charging - can it be so?
I'm still trying to wrap my head around the solar and power issue, but I have learned a lot. In conversation with my RV service tech, an independent guy who takes pride in his knowledge and work, I wa...

so,
the panels will put out a constant voltage but the amps change.
In shade they still put out the same voltage, or does that drop? I have only experimented with different angles, not with shade.
If you have two 12v panels putting out 18 v each, 36 total in series, and going into a controller that will bounce the volts down to a lower number 13-14v, then all the shade is really doing on the battery side is reducing amps, not volts, since volts get changed anyway.??
no matter series or parallel, it seems the output is going to be decreased by the shaded cell, not the whole panel. I dont think I understand it fully.
I would rather have 15 volts with a lot of amps, than 20 volts with a weak amp supply.
