Free panels would be wonderful, but alas...Did I miss the cost of your solar system as a factor in the cost of your transportation or were your panels free.
The cost of the solar array is the basis for the $0.02/mile fuel cost.
To arrive at that value, I spread the up-front cost over the 30 year warranty period for the system, including inverters, then divided by the energy they'll provide over that period. (The warranty provides me with the minimum they'll produce at the end of that period.) That works out to a cost of $0.06 cents per kWh. My two EVs both average 4 miles/kWh, so the actual cost for the energy to run the cars is $0.015/mile, but I don't want to over-sell the benefit, so I round up to $0.02.
Note that I later updated that post to include the cost of road use tax, since that's built in to everyone else's fuels expense, and should be included for an accurate comparison.
If you're interested in the gory details, I'm willing to share the spreadsheet, but that's the high-level answer.
Of course the other cost is the two EVs, but I paid $15k for one of them and $25k for the other, both with under 10k on the odometer, so they really weren't more expensive than a used ICE car of similar mileage. I called that even, and focused on the fuel & maintenance as the actual difference.
