There are actual current contracts that agree to sell solar at under 2c/kWh. Construction of multiple reactors on the same location is very common, constructing a new reactor next to a reactor being decommissioned isn’t.
Please link. I've read about some far future contracts relying heavily on public subsidies but even those were at a higher price.
At that price, earnings would (depending largely on geography) be something like 160-400 USD / 1.8m² panel over a 20 year period. This needs to cover panel cost, inverters and electrical infrastructure, installation&decommission, land rent, loss due to some prematurely dead panels, administration etc.
I would presume it's a matter of very few new nuclear reactors being built. Some smaller sites will be decommissioned regardless though.
If 1kw is worth 0.01997 $/h * 24 * 0.266 * 365 * 20 = 930$. Of course they don’t instantly break exactly in year 20. They lose efficiency over time so averaging ~90% over 25 years which is ~100% over 22 years. https://sunelec.com/wp/wp-content/uploads/2020/09/P72_outlin...
I can’t find an exact breakdown of costs spent on panels vs interest, instillation, inverters etc. But, at most we are talking about fractions of a cent worth of subsides to hit 2c/kWh.
That's a calculation based on 1kW of installed capacity, which is about 3 of those 345W panels so the earning per panel over its lifetime (in sunny southern California btw) is about $310.
Also, here's a B.Sc. paper from my alma mater (English abstract in the paper) http://www.diva-portal.se/smash/get/diva2:1236618/FULLTEXT01...
that puts the current all inclusive production cost of nuclear power in Sweden (incl. funding for permanent spent fuel storage) at $0.03/kWh. That's an actual cost for stuff that actually exists today.
