You ignore the short daylight period during the winter, when the electricity consumption is the most important. There is no practical why to store the energy for the nights. At the end we end up with a cheap source of energy that covers only a fraction of our needs, and we have to maintain a second source of production for the rest of the time. We pay two times to keep the two system operational.

Nuclear is also cheap and doesn't have this limitation.

Nuclear is, last I checked, the same cost as the combination of PV with a sufficient number of batteries to be the backup.

And for transport we need some kind of storage system regardless (doesn't have to be batteries, but does have to exist), the scale of which is larger than needed to do anything we want with night/clouds/etc. issues with PV.

The factories to make those batteries are being built very quickly.

During the winter, the solar panel are efficient just for a couple of hours every days. Meanwhile, this is the moment of the year where the global consumption is the highest. We've yet to see a battery system able to hold enough power to balance these months of under production.

Why would you store electricity produced by Nuclear energy? You can adjust the production to match the needs.
