@Muleski, Harbor Freight had the kit on sale for $139 so that is all I am out at this point. I have an extra car battery and a 400W inverter so there is no outlay there and any internal wiring and outlets I choose to do will be used if I decide to do traditional electric. Yes, we get a good amount of sun in Reno, example, it hasn't rained in almost 3 months and bluebird every day. Like I said early on, all we will be using this for is for lights, charging the weedwacker and maybe a home meth lab, when Harbor Freight puts them on sale too.
