I'm rebuilding a Class C and I might be redoing the roof soon. I would like to run the wiring for solar panels now instead of doing it through the fridge vent later. The thing is that I won't be able to install the max wattage from the beginning so is it possible to run the wires now and keep on adding/ changing the panels later or do I have to decide now what the system will be and run the right gauge.
Thanks
