PG&E in Northern California. Same for Edison in Southern California.
The thing about my area (Peninsula, 20 minutes south of SF) is that its not hot enough to really justify A/C, my electrical+gas bill averages out below $200 a month and my roof is old enough where it would need to be replaced before solar is installed. So a $15-$20000 expense cost for solar would actually be closer to $30-$40,000 with roof replacement, plus potentially bringing ancient wiring in my home to code will cost another handfull of thousands.
Its akin to trying to fix a slow memory leak in your application and realizing you need to also upgrade a bunch of dependencies which no longer support the current version of your tools AND refactor the frontend.
