Nearly every install I've seen talked about on this forum has had exterior conduits. I called a half dozen friends/family that has solar and the installers all did through attic running of the lines and in the cases where inverters were on walls that had attic access, ran those line into the walls to the inverter.
So it is normal? I'm asking because half my array as proposed has an exterior conduit going about 130 feet vs if it just went through the attic which would be half the distance. Not only that, the only way to get that conduit on the exterior to where the inverter will be will require some 25+ bends (complicated in my case).
Is this a code thing? Cost thing? Both?
