THAT'S gonna leave a mark! 
Apparently you have a very special model S. The EPA says the model S gets slightly more than 3 miles per kWh. And that figure is known to be highly exaggerated.
My 15kw system has never made less than 100kWh in a day with sunlight that was January with still ten plus hours of daylight.
The typical 15kw solar panel system can be expected to produce around 60kWh in a day in a location with optimal conditions.
Math is racist apparently.
What race are you again? You may be are a math drop out or you may be prone to exaggeration, or you may be both. I am told these are common issues among those living in Dallas.
A 15kw system is 15,000 watts worth of panels it makes 15kWh per hour of sunlight and in North Texas is ten hours in the shortest day of the year. Mine are two axis tracking panels. So they reach full power as soon as the sun is up.
I leased a tesla for a year loved it, in City driving I got 4 miles to the kWh on the regular over my ten mile commute each way. On the motorway it’s 3 to 2.5 at 100not with the cruise set at that speed.
I’m so pale I burn in moonlight as to my race proud of it. I say I can out pink
red headed Irishman.
You don’t own solar it’s obvious you don’t. Nor have you ever owned a Tesla so let the men talk now

“I am told these are common issues among those living in Dallas.”
I am a Texan, living in a suburb of Dallas.
Your insult (joke or not) is not appreciated.
