Where is best location for solar controller
I'm putting together a new solar system for use with my Class C. I had a Renogy 100W solar suitcase which I had extended with a second 100W panel... this worked great until it was stolen this week :(...

#2 will have less loss because the connection through the long wire is at a lower current level (and higher voltage), so the ohmic loss in the wire will be lower. It's the same basic reason that the power lines on the poles to a house are usually operating at 7500 volts or so, rather than 240 volts.
