Yeah, looks like that's how it works. They store up potential energy when the panels work, and then release it as needed. This solves the storage problem associated with solar.

a 1kwh LifePo4 battery costs almost 220$, so batteries are still expensive as heck. water dams or hydrogen production are good ways of storing solar energy

And with batteries you only have a couple thousand charge cycles. With hydro-electric I feel like it's limitless.

It still needs to be maintained, but it's still gotta be way more cost effective in the long run.

Agreed. And I can imagine the turbines needs updates as well.

Yup, all sorts of stuff has to be maintained and repaired.
