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

Why put in high end Kyocera panels and cheep out on wire? 40 feet is a long way from the battery with a lot of voltage loss that you will never get back. Such a waste. If this is just going to be a battery maintainer, your little bitty #10 wire will be fine but if you are going to do some serious off grid camping, then go with at least # 4 cable as suggested. I have helped 3 others replace their factory installed #10 wire because their solar system didn't work as expected. In all cases there was big improvement.
