I think it's an argument for adding just the number you need to compensate for the power loses

Otoh I think people are forgetting there's a point where the maintenance gets to be more

[konschubert]

Old plants were often designed such that at peak production, they would saturate the grid connection.

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.

Given that over 40 years they changed everything but the panels themselves, what maintenance?

Presumably "infrastructure around to maintain the farm" has some costs.

Land. Property tax. inspections. That sort of thing...
