This is more from a lot of coal power plants being converted to gas over the past 20 years than solar overtaking the outputs of those power plants. Coal output shrinking, solar output rising, the lines have crossed.
Coal is unpopular in all but a few areas where coal mining is still a part of the local econonmy. I used to work near a coal plant and every day I'd go out to my car and it would have little black particles all over it. Nobody likes that, no matter what the President says.
It’s also from focused efforts to close coal plants, and rapid, massive deployment of solar in the last 20 years, and new technology emerging (better batteries and dispatch technologies) to make solar into a 24/7 resource.
For whatever reason, there’s a strong motivation for people to dismiss the gigantic global effort to transition the energy system away from fossil fuels, and claim that all that effort isn’t really doing anything. Thankfully, this is not true — determined people can change things for the better.
No, this is actually solar's output increasing.
Natural gas's share of electricity generation has been falling for five years straight:

Solar has also overtaken fossil gas.

Some of these plants are being retrofitted for dual firing. They can burn coal & natural gas at the same time. I wonder how that factors into these statistics.
The world is, roughly, deploying 1TW/solar PV a year at current rates. It took a while to get here, it won’t take as long to get to 100%.

Total electricity produced by coal + gas is down over the last 20 years. Total electricity production is up, the difference is from wind and solar.
This administration swapped to actively suppressing Wind and Solar via tariffs etc, and yet the trends continued because the underlying economic reality heavily favors battery backed solar.
