Which is better .....
I presently have 3 strings of 4 one hundred watt panels going into a combiner then into the Outback Flex 80. I'm adding 8 more 100 watt panels.
I can either do 4 strings of 5 or 5 strings of 4. The VMP of each panel is 18 volts, and the Imp of each panel is 5.56. I'm leaning towards 5 strings of 4 so I can turn off 2 strings during the winter when I don't use my Plug In Prius at the property where this array is located.
Thanks in advance, Chris
