Need help from all you seasoned EV and solar folks. We are in SDGE(San Diego) territory and buying electricity from the grid is like an ever increasing penalty. Household of two (about to have our first child), both of us work so peak time usage is pretty much nil except on weekends - this is subject to some changes once the kid arrives. Average usage across the last 12 months = 454 KwH/month. We have a model X on reservation which would spike up the monthly kwH usage by another 440 kwH (assumption: 15000 miles/yr X 0.350 KwH/Mile). Pre-EV annual usage = 5500 KwH Post-EV annual usage estimate = 10800 kwH We do get grandfathered into netmetering, and have the option to go with TOU/TOU-2 rates (lowest rate 0.17 c/kwH, still costs more than solar cost/kwh) So, give all the options above, should we be factoring in 100% household consumption + 100% EV consumption OR 100% household consumption + X% EV where X is the value I need your expert advice on.. some have said factor in 60% EV usage, some say put on the biggest system to cover all of your current and foreseeable usage. Please advise! Many thanks.
