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

Hi,
#10 will be just fine with a pwm controller. I would add a temperature sensor.
Hate to sound stupid but, where would I find a temp sensor and where would I connect it?
Thanks

Some controllers have a temperature sensor build in and if they are in the general area of the battery that's good enough. Note that batteries should be isolated from electronics due to their vapors.
Some controllers don't have a temperature sensor.
Knowing the temperature allows the controller to better adjust the amount of charge.
