Does Putting Two 6v Solar Panels In Series Create 12v

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.

Does putting two 6v solar panels in series create 12v. Solar panels are connected in parallel to obtain higher output current. You can then connect each 6 volt pair in parallel with another pair to create a larger 12 24 or 48 volt battery bank. However the latter type of connection is at the expense of efficiency. Each 6 volt battery pair operates as a single 12 volt battery.

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. 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. When installing solar panels in series the voltage adds up but the current stays the same for all of the elements. By connecting multiple solar panels in series we increase the system voltage.

In a solar power system the higher the voltage and the lower the energy losses along the cables to know the maximum system voltage we usually just need to turn the panel and read the label where the value is reported. It is therefore essential before making a parallel connection to carefully check the voltage of the solar panels. 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. Wiring batteries in parallel.

Now lets look at connecting solar panels in parallel. 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. Makes no difference if comparing apples to apples quality wise.

What you are missing or not understanding is battery quality and you only want to use a single string and avoid parallel strings. For example if you installed 5 solar panels in series with each solar panel rated at 12 volts and 5 amps you d still have 5 amps but a full 60 volts. Let s look at a numerical example. 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.

This is usually used with 12v set ups. They might be for example one monocrystalline and one polycrystalline solar panel. Here is a very clear picture. Putting panels in series makes it so the voltage of the array increases.

The result would be a battery bank that produces 12v and 225ah. Say you have 2 x 100 watt solar panels and a 12v battery bank. To produce a 12 volt output two 6 volt deep cycle batteries must be wired in series positive to negative. This is called a series parallel configuration.

In our illustration we show two 6v batteries with 225ah wired together.
