Most panels create electricity that is DC and in the 9 to 24 volt range. That power is then run through a converter to create the 120VAC power. Many systems now are no longer attached to the grid. People instead have a secondary system in the house, some times with a relay, so the solar power is used for things in the home, but when the solar power level drops, it switches back to the grid connection.
The big problem with solar is that the electric companies need to maintain enough capacity to meet demand. On a nice sunny day there could be quite a bit of demand met by solar, but if a storm system rolled through, that solar would be interrupted, and then the utility would have to bring additional generating capacity on line to avoid brown outs. It takes time to get a boiler fired and up to capacity. I used to operate a small production boiler, 1.2 million horse power. It took over an hour to start that thing from cold. If I remember correctly, the power company is required to maintain operation at something like 140% of projected demand. In other words, if, based on history, demand for a Saturday in May is projected to be 1,000 megawatts, they need to have generating capacity on line to produce 1,400 megawatts even if actual demand is running at say 800 megawatts because solar or wind power is generating 200 megawatts.
The companies constantly monitor demand. If an unusually hot day causes demand to spike, as soon as they cross a threshold of 80% consumption, they need to bring generators on line to get back to the 70% line. Those are the numbers I remember from decades ago. It could have changed.
