Everyone always forgets that they only perform at less than half of their rated capacity and require significant battery installations. Rooftop solar plus storage is actually more expensive than nuclear on a comparable system LCOE due to their lack of efficiency of scale. Rooftop solar plus storage is about the most expensive form of electricity on earth, maybe excluding gas peaker plants.

Everyone also forgets the speed of price decline for solar and battery your statement is completely false propaganda made up by power companies. Today rooftop solar and battery is cost competitive to nuclear already in many countries like India
Do you have some citations?
You’re right that rooftop solar and storage have costs and efficiency limits, but those are improving quickly.

Rooftop solar harnesses energy from the sun, which is powered by nuclear fusion—arguably the most effective nuclear reactor in our solar system.

It varies by a lot of factors but it’s way less than half. Photovoltaic panels have around 10% capacity utilization vs 50-70% for a gas or nuke plant.
The thing everyone forgets is that all good energy technology is seized by governments for military purposes and to preserve the status quo. God knows how far it progressed.

What a joke
