Hooking up your own power to the grid is always going to be politically complicated. The places where it isn't are the places where there isn't enough of it for anyone to notice. When you introduce a special pricing structure that tries to prevent certain people from paying for certain power (51% of solar power must go to low-income people?) that just makes no sense according to the known laws of physics and it's no surprise it's problematic.
Presumably non-grid-connected projects are unaffected.
The BIPOC and LGBTQ communities are disproportionately impacted by the unjust distribution of electric potential so I don't see any problem with California requiring that PG&E work to achieve Electron Justice and ensure that those electrons whose voltages were created by clean solar energy are distributed equitably.
