Solar charging with some shade
I'm facing west today, so I'm getting a pretty good shadow on one of six series-connected panels. Panels are all around 135w @ 12v. Shade is on the far-left panel - about half of it: No...

I just tried lowering the front panel. With the sun's lower angle I can't make any appreciable difference in the shadow until that panel is near flat. So I'm leaving it.
When I get time I may try adding a couple mounting brackets to be able to scoot the shadowed panel's bottom back a foot. That will increase its tilt angle, but not anything significant.

If you parallel connect panels and the voltage on one is 2 volts while the voltage on the other is 12 volts, the 2 volt panel would act as a load--unless there are blocking diodes.
