Way too much. If you are paying over $0.25 for your electricity, save money & buy an ICE hybrid. For "everyday" non-demand charging the costs must be below this threshold (in today's dollars).charge $0.50/kW for charging.
I can go 250mi on 60KWH, call it 4.1m/kwh. Problem is it can be closer to 80KWH to put 60 in the car, depending, so lets start with 3.2 to be generous. My much larger hybrid sonata got around 42MPG,
250/42 ~= 6 gallons of fuel * 4.00 = $24 with an ICE
250/$24 = 10.4 miles / dollar
$1/3.2(KW) = $0.31/KWH to equal a gas powered vehicle, with $4/gal gas.
So If you are paying $0.50 .50/.31 * 4 = $6.45/gal equivilent. Ouch. If gas drops to $3: 3/4*..31 = $0.23/KWH.
Numbers and maths, bottom line: roughly $3.25/gal fuel is $0.25/KWH electric. Which means you need to be drastically lower to get a savings benefit from an EV. Power here is 0.08 off peak so about 1/3 the cost of gas. Amortizing this cost against the solar spend who knows.
