That said I'm pretty sure that grid-scale solar is the future of most solar energy, not home solar. It's just cheaper to do things in bigger batches.
Edit: though if we ever get to self driving cars there should be a whole lot of parking lots in metro areas that aren’t needed.
The reason for the high burden today is people have developed an inflated sense of how much the kWh they generate is worth. They install massive systems on their roofs to try to "cancel out" their power bill by exporting their entire daily power consumption over the course of a few sunny hours, which (when all their neighbors do the same) ends up being a costly burden for grid operators who then pass the costs on to users without panels. Smaller systems focused on immediate, local consumption rather than export are much better for the grid which is why they have support.

I have leftover panels from an off grid install, and its extremely hard to get an approved permit for a small roof solar array + off the shelf AIO (Ecoflow/Anker)
