    Roof shingles have a lot of overlap to ensure that water doesn't get into your house. Solar panels, not so much. Would you trust six feet of snow on top of only solar panels? I wouldn't. Consider Buffalo this week:

    My installer told me that the air gap under the panels was essential to reduce the heating under direct sun. If the panels replace the roof, it works seem like you'd need a way to address that - either very good attic ventilation or possibly liquid cooled panels.Walter

    I remember reading something to the effect that if you get the gap right it also helps insulation in winter.
