What gauge wire?
I'm going to be adding a second solar panel and need to know what gauge wire I need for 2/140w panels on a 35' run. Thanks Keith

Sorry, guess I should have gave a little more information.
I have a Blue Sky 30 PWM 30a controller and a single 140w Kyocerna panel and will be adding another Kyocerna 140w or 160w, haven't decided yet, panel.
The total run, panel to controller, is about 35'10ga then about 5'of 10ga from controller to battery. I will be updating the controller to battery to 8ga with the new panel but don't know if I should upgrade the 35' run to 8ga or run a second 10/2 wire along with the one that is already there.
