again. no it wont

its all one long wire.

they will be the same regardless of if you have a 4 inch and a 4 foot piece togethor.

the panels are all connected at the same point. they are all drawing the same power and splitting the same line.

they will be the same! I can go into more detail if youd like?

Edit:

I'll ad a bit more.

The panels are all wired in Parallel. so it matters not in what arrangement they are. the + side of EVERY panel is essentially touching and the Negative side of evrey panel are touching. there for they are all in parallel

IF you were wiring in series. and have different panels in series I.E. 4 panels in series on one line and 8 panels in series on a seperate line. than YES they would run different temps if on the same t-stat

But please if you think or know I'm wrong feel free to explain and we can discuss it. I do have 4 years of school related to electronics and electrical
