When you connect solar panels together in parallel, the total voltage output remains the same as for a single panel, but the output current becomes the sum of the output of each panel as shown. In this method, all the solar panels are of the same type and power rating.
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).
To connect solar panels in parallel, connect all of the positive wires together. Do the same with the negative wires. Be sure that you are using the right wires before connecting the panels. When you connect solar panels in parallel, the amps (current) increase but the voltage doesn’t.
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.
If we have two solar panels with same voltage and power, the connection will be very simple. As clearly visible in the picture, it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one.
The major practical difference between wiring identical solar panels in series or in parallel is what happens to the output current and voltage in each case: Series connection → Total output current of the entire system is equal to the output current of just one panel. The output voltage of the system is additive across all panels.
