If you are wondering about the cost to move a vent from one location to another, it cost me 350$ to move 3 vents. This is in West Houston, Texas.

I had previously asked for a redesign and they turned it in a couple of days. That redesign did not work out and so, I returned to my previous original layout. Hope this does not cause a delay to the install date.
In my experience, the installers are experienced enough to make layout changes on the fly. There was a bit of an unexpected ridge near my chimney that led them to move a panel on install day.

Hi all, I'm hoping to get some opinions on the placement of panels on my install. I need a total of 19 to 20 panels and I'm not having Powerwall installed.
Here's what Tesla proposes:

And here's what I'd like to see:

I prefer to have as many west facing panels as possible, because I'm on SCE Time of Use plan which charges $0.42/W from 4-9pm, compared to $0.14/W all other time. I want to maximize production as the sun goes down, so I don't want the majority of my panels facing east.
What do you all think? Is it unreasonable to ask Tesla to place the panels in 4 roof planes? I've emailed my advisors multiple times, and he does not respond to this question, and he kept sending a canned response via text "documents are ready for your to sign on Tesla website" with the same design layout of what Tesla proposes. I asked for a job walkthrough before the install, and my advisor essentially declined to do that.
I've previously had another company actually come out and walk the roof, and they proposed this below (back when I wanted only 12 panels). Notice they could put 8 on the west facing roof planes. Their panel size is 1558x1046mm, where as the Tesla Q cell panels are 1740x1030mm. Even though the Tesla panels are longer length wise, my feeling is that they should still be able to fit 7 panels facing west (4+3).

#2 Move as many as possible from East to West.
Prefering West over South while maintaining East does not make sense. South makes the most total kWh and West makes more valuable ($/kWh) energy than East. This all assumes no difference in shading.
BTW, I ended up going with the 5 PM - 8 PM SCE plan instead of the 4 PM - 9 PM plan. Yes, it is a bit more during those three hours, but I figured it is easier to control usage during 3 hours instead of 5 hours. For example, pre-cooling the house from 4 PM - 5 PM so AC likely isn't needed after 5 PM.
I have an install date! It's a two-day install. November 10-11.
Got some good news. An opening came up and now my install is scheduled for tomorrow, 9/25. Woohoo!
Nice! Good luck!
So inspection was failed. The big no no is they used the same breakers from the old panel on the new panel and since it is a new panel they need to bring the breakers up to 2017 code. There were other things not labelled correctly. Inspector even offered to meet the Tesla electrician the day of the corrections to pass inspection. So now it is hurry up and wait.Yep as it turns out the inspector would need to turn off the power to check the safety guards. So that would kill my internet connection for my remote garage control. So inspection delayed until Tuesday, my day off. I appreciate Tesla trying to work with me.
Last night Tesla Energy sent out a tech to get thing labelled and to take a look at the breaker panel. This morning they were fixing the remaining issues and right now they are waiting for the inspector. I really love the effort they are showing trying to get this passed this week.
Here is the new label:

EDIT: I was just notified we passed inspection. Now just waiting for my power company.
I posted the initial layout on page 25 and asked for an updated layout. Tesla said it would take 2-3 weeks. In the meantime, a home assessment was scheduled and I explained the changes I would like to the assessor. Within 3 hours after the assessment I received an updated layout. This layout will produce about 12% more energy per year

I also got a call today asking if I was around in the morning to begin our install. We were set for Monday and Tuesday. Now, Sat/Mon/Tues. They said it was because it is a complicated job. We ordered a large system with 2 PW. Panels are on two roof areas.Quarter-end push to recognize revenue, just like the vehicle side.
