Isn’t that an even stronger argument for upgrading an existing plant in situ versus spinning a new one up?
Otoh I think people are forgetting there's a point where the maintenance gets to be more
Land. Property tax. inspections. That sort of thing...
If you re-power that plant with more efficient panels, your production will sometimes be capped by the grid connection. But it’s fine because you will have significantly higher production in the morning and evening hours.
This can make financial sense.
I hope they put the used panels on the second hand market, such that users with different economics ( home installs, countries with lower labour and land costs) can buy and use them.
