[C320-list] Solar panels and shading

[sail-ability sail-ability]

   I'm sorry but this is incorrect, the panels can indeed be connected in
   Series so that they put out 24V same as connecting 12V batteries in
   series to produce 24V.

   Since most Panels have reverse polarity protection you don’t want to
   put them in series, you can simply parallel them (in theory)

   I have a single 180W panel on the davits on Luffin Life. Never had a
   shading issue due to location of the panel. I have learned however that
   if you have two panels hooked in series that the shading issue is
   mitigated somewhat. There's a guy in Mississauga ON (S.A.W.
   Technologies) who sells semiflex 100W panels which weigh in at 4lb. The
   issue is that you need a controller which will handle 24V; my Blue Sky
   controller will do that. I'm thinking of an upgrade as my single solid
   panel weighs in at 40lb and difficult to handle. I think those panels
   come in at 280 CAD each.

   Cheers

     Keep in mind that you can always add another panel someplace else if
     you
     have two smaller spaces or to keep one in the sun.
