Question

[Russ]

If six 3v/200mA-rated photovoltaic cells that are connected in series and six more 3v/200mA rated photovoltaic cells also connected in series and placed in parallel with the first set of six, what is the total voltage of the combination of photovoltaic cells?

Thanks

The same as each separate series string - that is 6 x 3V = 18V.

The amperage adds for parallel PV strings, not the voltage, so you'll end up with a nominal 18V, 400 mA array.

If you put six 3 V, 200 mA supplies in series, you get an 18 V, 200 mA supply.

If you put this 18 V, 200 mA supply in parallel with another 18 V, 200 mA supply, you get an 18 V, 400 mA supply.

The rule to remember is that series voltages add up, parallel currents add up.

Hmm, hope this isn't a joke, but 6 X 3 volts(series)=18 volts @ 200mA + 18 volts @ 200mA (series) in parallel with first series is still 18 volts @ 400 mA output (if the spec numbers can be trusted).

 No, not a joke. Thank you  VERY much. 👍

You're very welcome.

NOTE: They may not share perfectly in parallel though. You need to keep them both aligned perfectly. In some cases, you may not achieve the
full 400mA, but should be close
