15% humidity lol, NOT here.. I work a bit and break a bit and suck down a least 1 bottle of water each break.. As you country men know we are regular bad a$$'es when you couple us to machinery.. Me and my tractor oh the feats we can accomplish.. 18 ft 2 in panel roughly 50 lbs, 3 holes and the electric hole had to be spilt since ya can't just disconnect the juice line.. It wasn't fun but it's in place and now for a little fine trimming..
