That's true - since ICE engines have NO depreciation, repair, or breakdown and thus last forever then the only cost for them is the $.12/mile gastrue that.... solar energy is NOT 'free'; but rather best expressed as the net cost after all tax credits / warranteed energy production. cheap solar panels typically only have 10 yr warranty which lots of people forget when they go for the low bid. Much better to go for the 'premium' panels with 25 year parts and labor warranty.
I'd estimate that in most markets around the US, the 'true' cost of rooftop solar energy is probably around $.05-$.07/kWhr, which translates to lets say $0.02/mile in the average EV.
The other cost that many EV drivers choose to ignore is the amortized cost of batteries, which really are 'consumable'... If you take approximate 'replacement cost' of the battery pack/ expect warranted miles it becomes clear that cost is more significant than the energy.... on the order of $8000/100,000 = $0.08/mile
NOW you have some numbers to compare....
$.10 / mile for an EV running on sunshine, approximately.....
so, assuming the 'equivalent' ICE would get 25 miles/gallon, at $3/gallon, in a ICE Mustang for instance, the 'fuel cost' on the ICE side is more like $3/25 =
$.12 / mile
or, maybe a little more if you fold in the higher cost of maintenance for ICE engine and oil changes which is not insignificant over 100k miles. ie $50 just for oil every 5k miles with no other repairs is $1000 or so just for oil!
....so , yes, running on your own sunshine in the EV is less expensive, but really only when gas is over about $2.75/gallon if you consider batteries to be consumable.
There's also the fact that the battery is warranted at a MINIMUM to retain 70% after 100k miles, so in reality the battery is likely to outlive the chassis. But yeah, ICE is definitely the lower TCO
