I'm wiring solar panels, and I added one of these breakers between the panels and the charge controller. I'm aware that it's just one of many clones of this breaker design.
One terminal is labelled "Batt Line" and the other "Aux Load". So conventional logic would mean the panels get connected to the Batt Line terminal, since they are supplying the power.
However, the panels aren't supplying THAT much power. And the idea here isn't to protect the batteries from the panels, it's to protect the panels from the batteries.
I can't even find any mention of whether these units are polarized, so maybe it doesn't matter?
