Logical grid-tie solar wiring

[mostlybirch]

Hello,
I am planning the grid-side of a grid-tied solar system to write-up the one line diagram for the utility. I currently have a 200a service entrance with two 100a breakers feeding a house panel and garage panel. Ideally, I would run the solar through the safety shutoff and into the main distribution panel. However both circuits are full. I believe this leaves me with the option of running the AC from the indoor inverter outdoors to the safety switch and back indoors to the garage panel OR build another sub outdoors. What would be the most logical, or tidiest option here, ideally with the option to add a generator interlock?

Thanks
