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...

if it hurts the string to lower the front panel, why doesn't it hurt the string the same way to have the back panel shaded so much?
Wouldn't it be better to just disconnect that back panel when you are facing West with the fronts all tilted up?
I know this has been explained several times about how it works with a string, but I am still confused. (A "string" means they are in series AFAIK) Perhaps somebody would be kind enough to try and explain this again.
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.
