As I postulated in another post, this kind of has to happen. "Selling back" power to the utility at your buy rate is a gross economic distortion, it must end or the power company will cease to exist. And the power company can put in panels cheaper than most homeowners can (economy of scale and putting the panels in the "right" spot, rather than what's available on your roof), they don't want my/your power, they can happily build their own generation facilities.
Right now a lot of the solar economy exists on a premise that cannot scale; effective "free riding" the system.
The problem for the power company is storage, they have no way to store tons of power generated (either by them or homeowners) during the day, so they need all the generation infrastructure they would have anyway, PLUS all the renewables, either directly owned or by proxy via grid tie sell back.
The longer term problem is that once battery storage becomes cost effective, why have a link to the power company at all? Just put in enough panels and batteries and then pull the plug. The cost of electric for everyone still connected to the grid will, of course, go up, but that will only accelerate the move to solar + battery.
In 50 years, the vast, vast majority of power sales will be in high density areas (where solar cannot work; cities, high rises, etc). Those in the suburbs and rural areas; it will be much cheaper to just generate and self consume.
This presents a massive problem for the utilities in the medium term, the transition to serving only urban areas coupled with the requirement to serve rural areas and the ease at disconnecting entirely sets up a "heads I win, tails you lose" situation for them. The rules will have to change, perhaps we will all be required to have a power drop with a significant minimum bill to fund the grid; or the requirement to service everyone in an area will drop, and you'll find lower income rural residents getting clobbered.
Also, the other point they made I kind of discovered and talked about in a different post. If you're not willing to do a solar build yourself, the economics don't work. The installer is capturing pretty much all the benefit, you're left with a solar array that has a multi-decade ROI, and that's assuming (a wildly incorrect assumption, IMHO) that the power company doesn't change the rules to be even less attractive for home solar.
