Just check a few things first.
How to connect 4 solar panels together.
A series parallel connection is accomplished by using both a series and a parallel connection.
Please see diagram below.
This is called a string.
Are the solar panels compatible.
The best way to find out is to contact your solar panel supplier.
Then they are connected to the charge controller or to the inverter of the solar system.
You too can connect two solar panels into one system just like we do.
Every time you group panels together in series whether is 2 4 10 100 etc.

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same.
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.
They can be wired in parallel.
It allows you to connect two panels then connect them into one solar input.
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.
The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery.
Connecting solar panels in parallel wiring solar panels in parallel implies connecting positive terminals of each panel together and wiring the negative terminals of each panel together as well.
On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the.
When doing a series parallel connection you are essentially paralleling 2 or more equal strings together.
For example a 110ah battery should never be connected to a panel more than 11w without a solar controller and if you are using a solar controller you do not need a blocking diode.
If we have two solar panels with the same voltage but different wattage there is no problem.
