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.

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.
