Does anyone here have a home solar installation that is large enough to cover 100% of your daily driving? How is it working for you?

Does anyone here have a home solar installation that is large enough to cover 100% of your daily driving? How is it working for you?
If you are planning on adding a PV system to the house to take care of both house and EV needs, a caveat here.
In SoCal, my utility's (Glendale W&P) PV policy restricts residential PV installations to 110% of prior 12 months usage. So, unfortunately because I planned for a PV installation just 2 months after I got my Tesla, I could only install a PV system whose capacity was limited by my prior year's reduced electricity usage due to LED bulb replacements, attic insulation upgrade and only 2 months of Tesla charging.
So if your utility has similar short sighted policies - you may want to time your EV purchase and PV installation accordingly.
So far this year I am running about 7% below PV output required to make me a net zero utility electricity user. Time of Use savings are inconsequential since I am generating all electricity needs during prime time, so for sure I will be paying lowest Tier One rates only.

In theory, yes, but it's all tied together. I have a 9 kW solar plant that - on a good day - will generate between 50 and 60 kWh of power, well more than I use on the car. Over the course of a year, it accounts for about 25% of my electricity consumption for my home, including car charging.
Yup. 29kW system that powers house, stables and both cars.
I have a 4k system that does not cover all my usage. However, I went on time of use rate with Southern California Edison and by shifting loads I have a zero bill even though I am a net consumer. My monthly bills show negative dollars and positive kWhrs consumption. I get nothing back, nor am i charge anything at annual true up.
I'm also with GWP. Perhaps, if you installed your system for expandability, after another year your usage will be high enough to add another 10% of PV? GWP records both your PV output and the net value so the previous 12 mos average can be calculated from that.
I suspect the 110% number is somewhat driven by concern for loading of the transformer that supplies your home. Have you explained the recent adjustments to your electrical load (LEDs, EV etc)? When I dealt with them for my PV self-install 6 yrs ago, they were very accommodating to various adjustments to their existing policies. Hope they haven't changed for the worse.
Boy, that thread is full of a lot of bile.
