The thing is, the industry of your country doesn't turn off many factories, even during night. They suck juice.

Also, for shops, mall, offices, there is a prolongued pic during the day, and you can't offset that.

Also, your solution assume:

- a lot of smart connected systems (for the heating, the washing machines, etc)

- massive EV parks

- rétrofit buildings to fit those big rocks, heat them, and get heat from them

This is not trivial and would add to the cost to sell renewable energies, which are already not easy to market.
