Rooftop solar panels are flooding California’s grid. That’s a problem. As electricity prices go negative, the Golden State is struggling to offload a glut of solar power (wapo.st)

I'll note that right now, this is a seasonal issue, associated with moderate springtime temperatures when there is a lot of sunshine available.

Kind of, yeah. But excess solar can be turned off almost instantly so it isn't like it's an impossible problem.

Sorry for asking all these questions, but how do you turn off solar? Doesn’t it keep generating while there’s sunlight?

Just disconnect the panel.

If it's turned off, it's like a battery that isn't connected to anything. You have a voltage across the positive and negative terminals, but power can't actually flow unless there's somewhere for it to go.
