Unless you have very cheap grid power / terrible sun / needlessly high installation costs, PV will be a winner. So Quebec is bad because electricity is absurdly cheap, and the only benefit is redundancy. California should be absurdly cheap but regulations are out of control. Germany also has insane regulatory burden and expensive labour but grid energy is even more expensive, double the US average.
In very sunny places with expensive grid power a battery is sensible, but again politics often favours flat rate tariffs that discount peak power, which again favours grid incumbents.
So it might not be economic for your region but that is entirely due to regional politics, a default choice to make PV power expensive.
