To do this connect the first 2 solar panels in series and do the same for the rest two solar panels.
How to connect solar panel in series and parallel.
To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below.
While we re not going to get too deep into the details the difference between connecting solar panels in series vs in parallel is an intermediate level solar discussion.
This is called a string.
Connecting your solar panel in series vs parallel affects current flow and is dictated by your installation s setup.
Should you connect a 3a solar panel to a 3 5a solar panel the all round current will probably be pulled down to 3a.
The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage.
When solar panels are wired in parallel the positive terminal from one panel is connected to the positive terminal of another panel and the negative terminals of the two panels are connected together.
Connecting solar panels in series.
Comparing solar panels in series vs.
Now connect these two sets of series connected pv panels in parallel as shown in the following fig.
Please see diagram below.
Typically solar panels of specific or matching current needs to be connected with each other in series.
This kind of a lowering of current would of course cause a loss of power output and eventually loss in equipment efficiency.
Every time you group panels together in series whether is 2 4 10 100 etc.
When doing a series parallel connection you are essentially paralleling 2 or more equal strings together.
In fact by wiring several solar panels in series we increase the voltage keeping the same current while wiring them in parallel we increase the current keeping the same voltage.
The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector.
Make two pairs of two series connected solar panels.
