You'll get ~20 miles worth of charge per day in ideal circumstances (and you'll probably need an inverter.)
What? ~20 miles a day? Math please?
A typical EV gets around 3 miles per kWhr.... so at 9.3 kWhr of generation you get around 27-30 miles of range added to an EV with this setup. That's if all of the panels are set up optimally and getting sun the entire day.

From manufacturer: 780wh/day per panel in ideal circumstances
780wh*12 panels = 9360wh/day
EVs (as a whole) average 340wh/mile
So 9360/340 = 27 miles before inverter and charging losses. If both inverter and charging are 90% efficient, you're at 22 miles per day. When I'm making that many best case assumptions, I'm not going to give a number like 22 because it's too precise and people can pick it a part, ~20 covers my all my bases.

Nice. That makes sense. I appreciate you sharing

If you're going to use these, one has to verify the numbers it uses, the calculation it uses, and the result. If someone is just taking the answers and parroting them out to the world, they're going to look like a fool.
