>...How about installing roof solar panels and a Powerwall to run your house mostly off solar power.
Then fit as many EV charge points as you like, connected to the house system.
After the setup costs you could get quite an income.

No.  Rooftop solar doesn't collect enough energy to keep a Tesla charged.  There isn't enough area on most people's roofs.  If there is enough roof area on a Californian's roof to solar charge a Tesla, that homeowner is not the least bit concerned about the cost of power.

Solar power is clean and hip, but it is very diffuse.  I noticed one of the biggest activities in this area is a company which offers to remove your solar panels and take them away, free.  Plenty of homeowners looked at the output, the cost savings of generating solar panels, and let the guys come and get those things down.  If people had those on the back of their houses (away from the street) where they don't show, then they likely kept them.  But a lot of street-side panels have been removed in the past few years.

The power wall is cool however.  In the event of a rolling blackout, if you go to the expense of setting up an isolator switch, an uninterruptable power supply with the inverters and all that, it is a great asset.  If one is a work-at-home sort, you go right on with your business during a rolling blackout, which we all know is coming once again as the Tesla sales march along.  Then if one gets a good mobile generator, one can recharge one's power wall if a general power failure looks like it will last a few days or more.  Given a sincere enough generator (say a 10kW) and a power wall, one could even recharge one's Tesla with it.  People with sufficient capital will do stuff like that.  I don't see why the heck not.
