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).
Parallel wiring is a method of connecting multiple electrical devices or components in such a way that the current is distributed evenly across each device. In the case of solar panels, parallel wiring involves connecting the positive terminals of each panel together and the negative terminals together.
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.
This means that if you wire four 12V solar panels in parallel, the total voltage output will still be 12V, but the current output will be four times higher than that of a single panel. Here is a diagram illustrating the wiring of solar panels in parallel:
