Divert Plumbing Vents on Roof (Solution)

Finally found a solution to divert those vent pipes.  They're always taking up space in which extra panels could be, such a waste.
Code changes now allow for a product called Solar Roof Jack to Divert.   Haven't had any problems with inspectors and they all give instant approval.

    The roof vents are often the easiest way for a plumber with a snake to clear a clog.  Most houses don't have clean-out plugs, and if you can't snake through a roof vent, you have to open lines up under a sink - messy and stinky.

    I'd like to hear from the plumbing experts about having vent pipes lay horizontally in freezing weather conditions.  Especially long horizontal runs.

    I see very little benefit to these other than, for aesthetic reasons, being able to squeeze another panel in that will spend the majority of its time in the shadow of a vent. Might as well put a dummy panel there.

    If using such a thing, why wouldn't you run the opening to the north side of the array? That would avoid shadowing and provide roof slope to the +/- horizontal part for drainage.
    Off-grid.

    That would make more sense than the way it is being presented. Or just relocate the vent from inside the attic.
