times more expensive than nuke
>works only from 10am to 16 pm
The peak electrically demand is during the day.
Oh? You've checked the math?
Yes.
You can't transmit electricity an indefinite range
You don't need to put all the panels in the same place and you already use transmission lines to distribute power over long distances.
would cost the US $trillions to maintain
It'd be about half a trill to replace all the coal plants with wind turbines from memory. So yeah, not super cheap. But neither are things like nuclear reactors when you factor the whole build, maintain, fuel handling and decommissioning process. A lot of people criticise renewables for being subsidised but it's not a coincidence that people were so keen on reactors previous given the several hundred nuclear tests that have been performed.
Using the best of circumstances, we get about 5 peak sun hours per panel (the average in the US is less than 5, but w/e), and at 300w per panel, that's about 1.1kWh per panel. Or roughly 71 billion kWh. Too bad the US consumes 4 TRILLION kWh per year.
Somebody is full of shit.
If you model it using this map;
You'll discover that it's entirely doable even with a few hours of peak daylight in the US and that size of field.
