Help connecting solar cells to be 12 V
It doesn't work that way.

If you connect two groups in series, the output current you get is the lowest of the current from either group. Thus you'd get 12 V (11.5 + 0.5), but only 3.6 A.

Secondly, solar cells don't give maximum output all the time -- only under ideal conditions. Likely most of the time you'll get much less output than you expect. W

The best approach is to connect equal numbers in series (or in parallel) to generate a 'reasonable' voltage, and then use a DC/DC converter to convert that (varying) voltage to the one (12 V ?) that you want. Perhaps 4 paralleled groups of 10 in series might be a good starting point.
