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

An alternative is to leave the 35 ft, 10 awg cable in place and go serial. You now need a mppt charge controller. You may find a controller cheaper than new cable. If you go serial then the two panels have to match. 140W each.
