So if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series the voltage of the series would be 80 volts while the amperage would remain at 5 amps.
Does putting two 6v solar panels in series create 12v.
This is called a series parallel configuration.
However the latter type of connection is at the expense of efficiency.
In our illustration we show two 6v batteries with 225ah wired together.
To produce a 12 volt output two 6 volt deep cycle batteries must be wired in series positive to negative.
There are some major benefits to connecting solar panels in series.
You can use either 2 6 volt batteries in series or 1 12 volt battery.
The picture above depicts the connection of two different 12v solar panels.
This is usually used with 12v set ups.
So when connecting solar panels in series always try to keep the electrical properties of the solar panels identical to get the full benefit of the solar array.
Let s look at a numerical example.
It is therefore essential before making a parallel connection to carefully check the voltage of the solar panels.
You can then connect each 6 volt pair in parallel with another pair to create a larger 12 24 or 48 volt battery bank.
Wiring batteries in parallel.
Here is a very clear picture.
In a series configuration the batteries are wired per the diagram below and the result would be a doubling of the voltage while the capacity remains the same.
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.
Since each panel is 12v and the battery bank you want to charge is 12v then you need to parallel your system to keep the voltage the same.
What you are missing or not understanding is battery quality and you only want to use a single string and avoid parallel strings.
Putting panels in series makes it so the voltage of the array increases.
After these clarifications let s see how the series connection takes place.
By connecting multiple solar panels in series we increase the system voltage.
Say you have 2 x 100 watt solar panels and a 12v battery bank.
Each 6 volt battery pair operates as a single 12 volt battery.
Solar panels are connected in parallel to obtain higher output current.
100w 18vmp x 5 5a imp and 50w 18vmp x 2 77 imp designated for a solar power system of a 12v system voltage.
Now lets look at connecting solar panels in parallel.
When installing solar panels in series the voltage adds up but the current stays the same for all of the elements.
The result would be a battery bank that produces 12v and 225ah.
Makes no difference if comparing apples to apples quality wise.
