For the third example, we have 4 100W-12V solar panels. And same as the 2nd example, these panels are wired in 2S2P. However, the solar panels in this system need to charge 2 series wired 100Ah-12V batteries. So for this example: We have 2 parallel strings. 2 solar panels in each string. The power rating of our solar panels is 100W.
