what rate plan do you use? I'll be getting my MX soon, looking for the most efficient plan. Currently i'm with southern california edison, have a 5kW PV system and am on NEM 1.0. My electricity bill for the last 12 months was $35 for the year (plus the mandatory $10/mo connection fee.) Will prob drive 15000 miles/yr, so that's probably an additional 400-500 kWh per month charging. Was looking at time of use rates so i could charge cheaper at night, but for these the daytime rates seem kind of exorbitant. currently i pay or get credited 16 cents/kwh for tier 1 across the board whether day or night. The TOU EV-1 plan is 13 cents at night but 37cents/kwh during the day! seems high. not even sure if i can do TOU with NEM 1.0. anyway just wanted input as to what other tesla owners with solar do. thanks.
