I'm not sure why you don't wire it as 12 volts for efficiency but my thinking and I may be wrong, is...

Assuming all panels have Sun,

1. four in parallel - maximum amps (24? amps) 12 volts
2. four in series - 1/4 total amps (6? amps) 48 volts
3. series-parallel: 1/2 total amps (12? amps) 24 volts

W / V = A is based on 14V output, not 12

If the blocking diodes segregate the shaded panel/s, that will alter those numbers drastically w/ any series connection.
