Has anyone installed solar panels on the roof of their TT? If so, how did you run the wiring? I don't see where I could run this through the walls, so it would have to be an exterior run. If so, any ideas on how to protect the wiring?

refridge vent. conduit. Exterior runs usually look like hell.

or a tank vent stack. It will require drilling a hole in the stack inside and then sealing around the wire.

Use one of the vent pipes for the holding tanks or refrigerator vent to get the wires down to a storage compartment near the battery bank/controller.See this site for lots of RV solar info:http://www.jackdanmayer.com/rv_electrical_and_solar.htm

come down thru the roof / ceiling into a upper cabinent, then feed the rest thru interior routing. Our Terry has this "feature". The hole (sized for 14/2 ac wiring / romex or equivalent... 1/2 in hole maybe) is well caulked with dicor with no issue. The cabling on the roof is held down with standard cable clamps with screws (caulked accordingly).

A lot of folks choose the fridge vent. There is even a terminal block sold for this purpose so that you can parallel module wires to a larger cable to run to the solar controller.There are marine bulkhead fittings made for cables for boat use that would let an installer enter through the roof anywhere. These same fittings could be used through a wall. Some users mount a combiner box on the roof and lead wires down from that box. FWIW, I have 2 x 4 awg and a pair of THHN 14 AWG pulled through conduit over the edge of the roof and into the wall near my electrical distribution center. The conduit is along the side of a window.
