Optimal Panel Placement

As posted in other threads I've got a total of 10 415w 48v QCells panels I'm going to integrate into my (2) LV6548 + ESS setup. In previous posts (thanks to tons of helpful replies) it's pretty clear I'm either going to go with 4S2P with a string into each inverter or 3S3P with a couple strings into one MPP and the other string into the other inverter MPP.

My question here is related to placement on my rooftop. I went up there today to actually measure the space that I have and realized that these panels are freaking huge lol. As such I can't place all of them side by side like I wanted because it won't meet municipal permit setback of 3' from the ridge of the roof. As a matter of fact, the panels are so big that they would cover the entire side of my carport/garage roof that faces south (!) Attached is a photo with a 4S2P configuration on my house that will meet all required setbacks. Is this going to be the optimal placement/configuration for maximum PV or should I brainstorm a way to install 3S3P instead?

Thanks!

4s2p looks good to me.
Assuming that the voltage works for your MPPT's.
But the first paragraph is confusing.
4s2p would go to one MPPT. (8 of your 10 panels)
Unless you actually meant 4s1p (AKA 4s) to each?

The confusion is probably mine then. What would be the difference between running 4s2p into one MPPT and 4s1p into an MPPT on each inverter? I plan to use both so that I can supply an AC load center with 240v.

It's better to balance the system across both. Unless you plan to expand later.
Then it may make sense to just connect it to one, and save the other for future.
This also depends on the SCC limitations.

From what I hear you saying it would be better to run 4s1p to an MPPT on each inverter.

Ignorant question: does running 4s1p into separate MPPTs affect the amount of PV generated?

Correct
And
No, unless it is below or above the limits, in either configuration.
