Solar Installation Upgrade from 200 Watts to 400 Watts on Our Travel Trailer Series or Parallel ?

Heres my video on our upgrade from 200 watts to 400 watts using 100 watt solar panels.
I hope you watch the whole video to see my mistake of wiring the panels in Series in the beginning of the video and then changing to wiring in Parallel for better performance of the panels.
And go to the links I posted below to see the other videos I mentioned in the video. Thanks for Watching Note: Products I used and links to them are provided below.

Be responsible and know your limits. From Renogy Website - If you have an MPPT charge controller you have the option to wire your panels in series or parallel.
To determine which set-up is better we would answers to a few questions: 1.What is the distance you will have between your solar panels and charge controller? 2.Are your panels going to experience any type of constant shading throughout the day? 3.What type of battery bank do you want to charge: 12V or 24V? 1.
If your answer to this questions is longer than 20 -25 feet we would recommend connecting your panels in series.
When your panels are connected in series the operational voltage of the panels is added together.
If you are connecting two 100 Watt panels in series and each panel has an output of 18.9 volts you will end up with 200W 37.8 Volts and 5.29 amps under optimum conditions.
The higher voltage helps with the voltage drop caused by the large distance and allows the amperage to reach the controller efficiently. 2.
If you answered yes to this question we would recommend connecting your panels in parallel.
When your panels are connected in parallel you add the amperage together but the voltage stays the same.
For example if you have two RNG-100D 100 Watt panels each panel will produce about 5.29 amps.
Connecting these panels in parallel will produce 200 Watts 18.9V and 10.58 amps under optimum conditions.
