Does Wiring Solar Panels in Parallel Increase The Speed the Battery Can Charge At

Question:
I am trying to replace my estimated daily usage of 77AH to a Battle Born 100AH LiFpo4 and am concerned about cloudy days where there may not be enough sun hours. I was thinking no less than 2-100 watt solar panels to as many as 4-100AH solar panels. From the QandA Ive read here it seems that you can add up to 599 watts of Solar Panels to the Redarc Manager 30 so long as you stay below the max voltage input of 32 volts. Which in turn would mean that you would have to connect the solar panels in parallel, in order to stay below the 32 volts. Having said this, is there actually a benefit to be had by a set up like this? i.e. quicker charge time / greater charge Thanks,

Helpful Expert Reply:
When you wire anything in parallel you end up keeping the voltage the same but increasing the amperage. Since amperage is the biggest factor when charging a battery you would be greatly increasing the speed of the charge on the battery if the amperage/wattage increased by adding additional panels wired in parallel.
I also attached a help article link to this page that details how to pick out the amount of solar panel needed for an RV for you to check out as well.
