Yeah but are they big or small panels? They very on size. So I guess I'm looking more for the greatest watts per sq ft.

Actually, the lower kWh rate may be more correct. Before I changed to TOU with SCE in order to charge my car at a low rate, I talked to SCE customer service and had them run comparatives on representative winter and summer weeks during the previous year before getting my Tesla; TOU vs my then existing tiered rates. Lo and behold, TOU would have cost me $25 less for the year than my existing tiered rates, despite the much higher weekday afternoon-evening peak rates.

Nice setup and sweet beard! I guess my question was what dimensions are the panels or what model number and I can look them up.
Thanks!
I guess I could climb up there with a measuring tape-- I'm sure I have some documentation around-- I'll check.

Hah, no it's cool. I found the specs online. Appreciate you risking life and limb to try to help out.
I got something wrong....we have a 240v charger in the garage. In past couple years put in 2 HVAC split AC/Heat units, electric stove and have the 70D. We also have solar. Our usage went up average $83/month from before we put in any of these systems. Cost is .10/Kwh
We cut one tree down in back and getting a few more panels. I know cost per mile is cheaper and MUCH less pollution with our current system. Something I am missing?? HVAC use more juice than I thought?? I am going to put a meter on the charger to REALLY see how much juice it uses..travel is 50 round trip per day at most.

Amazing that you have ten cents per kW for electricity. We pay 48c per kW in the afternoons and early evenings.
What size solar system do you have on your roof?
The cost to charge at home for me is $0 or less than $0 as on some months I get paid by PG&E to charge my car for free given my drastically lowered PG&E rates with the EV-A rate.
My next door neighbor gets a much steeper discount given that his PG&E bill was in the $900 range and now with his Leaf it's in the $300 range with the same usage, so he's leasing a car for $200 bucks a month and saving himself $600 a month on usage so he's driving a car for free and netting $400 / month.
How did your neighbor spend that much? Did they heat and cool the inside and the outside of their home at the same time?
Yup. They're energy hogs with a pool, spa, etc and a 5000 square foot home without energy saving lighting. They could easily halve their usage.

I ended going with the Panasonic 330 watt panels. 27. Should be installed next month.
Tell us why you made that choice. Was it your choice or did those come with the solar panel company you chose? Did your company give you a choice of panels? Do you have a separate inverter box?
I am charging at super off peak TOU rate with SCE of $0.12/kWh. So far it hasn't cost me anything because I am using the grid to store energy during the day and SCE credits me at the rate of $0.37kWh for that generation,
I like your simple approach. I tell them I can go as far as I want. They often look puzzled which gets their attention. Then I tell them I am 73 years old and can only go an hour and a half before I have to pee. Superchargers are conveniently located along Interstate 5 and in the time it takes me to pee I have another 100 miles on the battery.

I choose the Panasonic panels because of the watts per square foot. I was challenged by no have a ton of space facing south so I need the most energy dense panels I could get. I could even get a quote on sunpower 345w so the Panasonic was there next best thing. My understanding is that the sun power where expensive. Just a single inverter, the panels do it have micro inverters but do have the diode bypass for dealing with shaded panels better. Not an expert on how that works but I get a bit if shade late I'm the afternoon and it will be worse in the winter.
