The only way I deal with hunting lodges and the like is to install close to full code (I do relax on the exact year, since it isn't new construction), or I supply parts and advice, and let them do it themselves. In Taos, we had some pretty poor folks trying to make it out in the desert, so I almost never turned anyone away, but not everyone got the benefits of a professional install. Try telling a fellow American living in a tent or plywood shanty that they have to comply with NEC 2011. Just to make you feel better: 12 v PV is one of the safest forms of electricity, so if the screw something up, they're not exactly going to vaporize the planet. They're much more likely to die in a car accident driving to your shop to get another fuse......
