If both panels are rated at the same maximum voltage then you ll get maximum output.
How to connect two solar panels to one controller.
The wire from the solar panel will be too short to run to your charge controller.
The fuse rating is specified in the solar panel datasheet or on the sticker at the back of the panel.
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.
Connecting two solar panels in parallel.
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.
Maximum rated current 5 8a.
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.
What is the problem if we connect the same solar panel to two controllers in parallel which in turn each one is connected to a different battery.
Maximum rated voltage 19 8v.
Parallel connection of two identical solar panels.
If we have two solar panels with same voltage and power the connection will be very simple.
Connect the two solar panels to the charge controller.
Series and parallel connection of two solar panels.
You can use an inline mc4 connector fuse.
