To solve this problem and to optimize the energy performance of the entire system, it is advisable to wire two panels in series (obtaining a doubling of the voltage) and then wire in parallel the three pairs previously wired in series (so as to have doubled the voltage and tripled the current).
When connecting solar panels in parallel, it’s crucial to prioritize safety. Firstly, ensure each panel is of the same voltage rating. Mismatched voltages can lead to inefficient charging and potential damage. Use fuses or circuit breakers on each line that feeds from the solar panel to the combiner box.
The next method of wiring solar panels is in parallel. In this configuration, all the positive ends are connected together, and all the negative ends are connected, maintaining the voltage but adding up the current. For our demonstration, we’ll only be able to use two panels due to the short circuit current of our panels (9.4A each).
For identical solar panels wired in a series-parallel configuration, for each series string the voltages are summed and the current stays the same. Then, for each series string of identical length wired in parallel, the currents are added and the voltage stays the same.
For identical panels wired in parallel, the currents are summed and the voltage stays the same. For example, let's go back to the scenario of 3 identical solar panels, all with a voltage of 12 volts and a current of 8 amps. When wired in parallel, the 3 connected panels will have a voltage of 12 volts and a current of 24 amps (8A + 8A + 8A).
In this case, it is possible to wire the two 6V panels in series and then wire the resultant array in parallel to the 12V panel. However, the latter type of connection is at the expense of efficiency. It is therefore essential, before making a parallel connection, to carefully check the voltage of the solar panels.

When Do You Need to Fuse Solar Panels? (and how to do it)
Remember that with parallel wiring the amperage increases, so the total short circuit current of this solar array is 36.27 Amps (12.09A x 3 panels = 36.27A).. In the event of a fault or short circuit in one of the panels, the other two panels would dump 24.18 Amps of current into the faulty panel (12.09A x 2 panels = 24.18A).
