This parallel wiring method is essential for 12V systems, including 12V charge controllers and inverters. Therefore, two or more solar panels and batteries (each rated at 12V DC) are connected in parallel to maintain system voltage while increasing current capacity.
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.
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).
Solar panel series and parallel connection diagram with four panels. Showing positive to negative wiring diagram for series. It means, for a balanced and efficient 24V solar system, you need at least 4 panels, configured as 2S2P (2 panels in Series, then 2 such strings in Parallel).
