I,m going to add another 100w panel to the camper and am not sure what size wire Lance used in 2011 12g or 10g it looks like 12g to me and if it is I will replace with 10g. Thanks for any help
I;m thinking I will just order the 20ft of 10g wire and run it across the roof into the cupboard were the 20amp controler is maybe 8ft away and leave the other panel on its own.
