PV Gap

Becky Said:

How much area would solar panels that produce 3,300 MW cover?

We Answered:

The other answer gave you a reasonable answer for a peak power of 3.3 GW. YOU said daylight hours only.

Now you want to talk 24 hours supply. You would need 3 to 5 times more solar power, so therefore 3 to 5 times more space. But batteries are not suitable to store this amount of power, so you would need perhaps pumped water storage, with a large reservoir, dams, and water turbines and generators and all of that, probably more expensive than the panels themselves.

But why 24 hour operation? most power is used during the daytime hours.

10 GW at $4000 per kW will cost 10000000 x $4000 or $40 000 000 000, $40 trillion dollars. Economies of scale will reduce that a lot, perhaps to $10 trillion dollars. A lot more than a nuclear plant.
