check with your HOA overlords. If you're placing 27-29 panels with a southern exposure, they'll want to see that somebody studied glare/reflection impact on your neighbors to across the open space.Just had a long conversation with Tesla because their numbers were wonky. They are going to re-model with the same information that I have provided to everybody else that they conveniently didn't look at, at all. It will likely be a custom size because the "medium size" is 24 panels, while "large size" is 10 more. Most are coming back with 27-29 panels and factoring a car, which they did not. We shall see in 2 days.
