I've read about places that don't actually do "net metering" and implement this with two separate meters, one for inflow and one for outflow.
Is that the case where you are? Are there any time-of-use options available that might sweeten the deal?

Assuming it were free (even to purchase, with only charge/inverter efficiency losses), of course it would. However, as much of the discussion in the thread points out, storage is very capital (if not maintenance) intensive, even at utility scale.
That's true, in that, if the metering is purely electronic, the only thing "separate" would be two different readouts. For electro-mechanical metering, I'd still expect a need for two physically separate ones.
Regardless, substituting "readouts" for "meters" is irrelevant to my question.
