How much dedicated time does the gas station take to make the gasoline?
Realistically I would assume the solar array would use a storage battery so you don't need to generate the power at the instant the Tesla drives up.
On the other hand, 26-53 Teslas/day may be a bit of a low number. I've been at Tesla recharging stations where there are two or three Teslas parked and charging at the same time. And this was in NJ, not the west coast where there are more Teslas on the road.
On the third hand, no one drives into a supercharger with a completely depleted battery. I would wager that most people are just topping off from less than 50% charge to 90%.
On the fourth hand, a Tesla charging station doesn't have to be run completely off solar panels. Panels can supplement and take some of the base load off of the hard lines.
