Some key insights from the article:

Basically, what they did was to look at how much batteries would be needed in a given area to provide constant power supply at least 97% of the time, and the calculate the costs of that solar+battery setup compared to coal and nuclear.

solar today is warranteed for 30 years. No reason to replace before 60 years compared to adding more beside it.

    Batteries and panels degrade over time. So if you are trying to maintain a specific amount of power you would need to keep investing in order to maintain the same amount of power generation

    I mean there are ongoing costs with any form of power generation. Obviously there's fuel costs for most, but even other renewables have maintenance costs. You'll also need to keep investing anyway as power demands increase over time. So newer solar installations eventually replace the old.

    Yes, what I am saying is that cost is being shown for nuclear and not shown for solar due to using an intentionally small window of time. It’s like comparing an ICE to an EV and talking about the refueling costs of gas and treating electricity like it’s free.
