Solar Panels, Sub Panels 
  Here's my situation: I have a detatched garage that would be perfect for putting a set of solar panels on. There is a subpanel that runs back to the main. Can I do all of the wiring of my solar array into the subpanel? Or do I have to run it all back to the main panel? Thanks, Scott
