With a lot of spreadsheet work you can figure out how the different rate plans will work for you with different scenarios of usage. E.g. what if we buy a PHEV to replace the ICE? E.g., what if we double our solar panels?
From SDG&E you can download a CSV file of your net meter data in 15 minute increments going back more than a year so you can map your net usage to TOU periods. From NREL you can estimate solar production by day and hour for your specific geographic location and PV installation parameters. http://pvwatts.nrel.gov/pvwatts.php I used this to estimate seasonal and daily variations but normalized the total to our actual total production. From SDG&E you *could* get TOU data for your EV sub-meter but they give it in XML format and I didn't want to write an XML parser so I just copied totals by TOU period from the past year of bills.
