This is a deceptive headline. The solar plants produced that much power during a few hours. The article is light on details (and makes a few basic errors) but at a bare minimum we can know that the average amount of power over an entire day was far less for these solar plants than these peak power figures, probably about 1/5th as much. Whereas nuclear plants keep producing all day long.
This is great propaganda for the solar power industry but it does little to change the fact that solar power doesn't produce power when it's needed and storing energy is extremely expensive. This is not an indication that solar power is ready for prime time, to serve as base load power generation, it's just an indication that if you build enough PV panels you can get a lot of power for a few hours on a sunny day, which is something we've always known.
