The linked article, "Rooftop solar panels are flooding California’s grid. That’s a problem.", is more interesting. It's becoming clear that solar and wind power have to be paired with batteries once the intermittent sources start to dominate. Fortunately, batteries are much cheaper than a few years ago, and get cheaper every year.

The article doesn't mention that California has a solar battery rebate program.[1] How's that working out? Rebate plans have to be carefully designed so that panels and batteries are installed in the right proportions.
