  • Whats inside a commercially built solar panel

    So I am trying to figure out, without buying one, what is inside a commercially built solar panel.

    Do they have cooling fans, backflow systems, what other electrical systems would come inside just the panel itself?

      No fans or extra parts in the commercial panels. Mostly they just have tighter cell spacing, better cell output, better soldering, proper code-approved wire of the proper size, higher vacuum, better seals to hold the vacuum, stronger frames, good glass, UV resistance

      Some more differences:
      UL Listed
      Warranty
      Better Output
      More Durable
      Won't make your insurance company freak out.
      Won't freak out the electric company.

      The reason why the efficiency of commercial solar panels are better is because they make the batches of cells. Then they test the cells. The cells that put out enough are used and the ones that don't measure up are sold off to someone who puts them on eBay.
