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.

Subsides are common for all forms of electricity generation, but LA’s 2019 1.997c/kWh power purchase agreement is hardly the far future. https://www.pv-magazine.com/2019/06/28/los-angeles-seeks-record-sub-two-cent-solar-power-price/ https://www.pv-magazine.com/2019/06/28/los-angeles-seeks-rec... Anyway to use a specific example Capacity factor 26.6% (average 2015–2018) https://en.wikipedia.org/wiki/Topaz_Solar_Farm https://en.wikipedia.org/wiki/Topaz_Solar_Farm. Bulk panels are $0.29 per W or 290$ per kW. PS-P72-330W https://sunelec.com/ https://sunelec.com/ 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_outline2.pdf 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.

  >"0.01997 $/h * 24 * 0.266 * 365 * 20 = 930$" 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 the $ sign goes in front of the number.

    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.pdf 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.
