depending on where you live, that's where grid pricing comes from. I live in Italy and in my solar panels I have a kind of net-metering (not quite, since I need still to pay transports costs for the energy I buy back from the grid). In a year, they will phase out this regime and every person with a solar array will become a "producer". Energy company will pay the gross market price for the energy that you feed to the grid (and this price it's updated hourly if not more often). That will essentially do what you suggest: owners will start caring more about timing, and the grid will benefit. If you still don't care and want to feed the grid at the time when everybody else is also.. well the energy won't be paid much. And viceversa

I prefer the local 1:1 kW banking that my electrical utility company offers: rather than being paid, all my excess generation gets "banked" and I can use it during heating season.

Obviously, if you generate more than 100% of your needs, you're going to want to get paid.

Yes, that's what's called net metering: https://en.wikipedia.org/wiki/Net_metering

However, despite being convenient for the user, it isn't great for the grid nor scalable if all users were to have solar panels. (Here in Italy solar on rooftops are quite widespread).

You can see that a kWh on a sunny summer noon when all panels the area are working well, isn't worth the same as a kWh in the cold winter night, where non-renewables often supply the grid.

Often by a huge margin. Electricity prices on the spot market can go negative, and that will happen more and more often in the future on sunny, windy days. Net metering at constant $/kWh prices is unsustainable, economically.
