Does anyone see a problem with routing the wires from the solar panel into and out of the vent tube for the bathroom?

I was thinking of some plumbers caulk or the equivalent to seal the hole I would have to drill.

Why? because it would the be the easiest and shortest run from the panel to the controller, and subsequently the batteries.

thanks

Hi,

The "Solar Prep" package on the Holiday Rambler that I installed a 400 watt solar system on was "Drill a hole in the roof here, and pull out the wires". So I measured 15" from the sidewall, and 10" back from the skylight, and cut a hole about 1" diameter, fished around with a coat hanger for 10 minutes and pulled out about 4' of #6 wires.

Sealed the hole with a lot of rubber roof sealant, and have a water tight handy box on top of the hole, with the solar panel mounted above that, so the box will never see any rain.

My suggestion? Cut a hole in the roof that will end up under the solar panel, and put a box over the new hole. Make sure that the hole will be over a cabinet that you can run the wires through without them being visible. You might have a TV cabinet you can run the wires through, or a closet that the wires can be routed in a way they can not be seen while looking into the closet, without climbing inside.

I ran #10 UV cable direct burial wire between my panels, and also to the controller. I have one pair of 120 watt on one #10 wire and 16 watts on the other #10 wire. This goes to a 50 amp solar boost controller, and #8 wire running to the batteries.

Fred.

Thats how I ran mine and it worked out fine. I was able to run them from the top of the vent and came out under the bathroom sink where I could easily fish them through to the basement. I also caulked up the pipe and no problems.

My professional installation was done the same way. The wires were routed next to the vent pipe.

My wires are run down alongside the pipe. A little Dicor and things are good

"I was thinking of some plumbers caulk or the equivalent to seal the hole I would have to drill." Use a very good sealant like Dicor.
