I don't know much about solar panels, so a silly question: If the panels are 15% efficient, what happens to the remaining 85% of the sun's energy?

  It's either reflected or turned into heat within the panel.

    So the solar panel itself heats up the environment, even if the roof is in shade?

      In the same way that a normal roof heats up the environment, yes.
