They could be put onto a single house, but it would take a pretty large house, my house sure as hell can't support anywhere near that amount of solar panels, especially with the way that some roofs are build. It also looks ugly if it completely fills out the roof like that, which is a large dealbreaker for most people and most importantly, it's expensive. That 10kW system would cost around 20K and is kinda overkill for most houses. Most houses just tend to go for 4-5 solar panels, for about 1 kw system that is enough for that single house. Some states still don't support selling electricity back to the grid, so a 10kW system is kinda overkill.
But that's houses, of course massive 100+ MW solar farms are still available. But even that's not enough. A Tesla supercharger is 120kW, but's let's simplify that to 100kw to make thing easier. A thousands cars, all needing charging at the same time, would need a 100 MW farm. That's only a thousand cars, when in some cities, there can be as many cars as the people living there. Not to mention that's assuming park sunshine, in the middle of the day. If it rains or in the early morning/late afternoon, your 10kW system could turn into a 1kW system.
I'm not saying that solar is bad, every joule that we squeeze out of it is free energy that we would have needed to burn fossil fuel for before but there's no way it's gonna to be the major energy source for the future. It's just there as a stop gap, there to supplement the grid until we finally get large scale nuclear power/high attitude wind farms/massive tidal power around.
