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...

Reduce one panel in the string to near zero amps, and the entire string is near zero. I think of it as a series of water pumps, each contributing to the pressure, but not the volume.
I know this has been explained several times about how it works with a string, but I am still confused. ...
How is tilting back an un-shaded panel in the string different from shading one, and whether it would be better to disconnect the back one and leave the tilted one up the same tilt as the others in the string or leave as is.
When you connect electrical devices together, you can increase volts or amps, but not both. Like batteries.. you get 12v from 2 -6v, but the amp-hours (capacity) remain the same.
Not sure I get the 2nd part..
