Which is better, Series or Parallel panels

You don't need to keep changing down to Float every day when you only get the batts to Vabs late in the day. If you balance your battery bank size with your array size that is how it happens, and you can let night time be your "float" time.

So you can stay in your hammock without having to go over and push a button on that cursed controller that makes you do all that work.

(This assumes you have someone to bring you beer while you are in your hammock. Otherwise, you could mount the controller by the fridge and push its button when you get another beer.)
