As for providing diagrams at the planning stage, not a set of city approved installed plans, I’d be willing to bet that the vast majority of homeowners buying a system don’t care to see the line-drawings. They just want it set up, get their PTO and know the system is being maintained. Seriously doubt most people have an electrical background or care to learn the specifics of what’s installed.
Also doubt Tesla has enough trained design planners available to answer tons of phone questions and still do their design work. Wildfires areas and others wanting solar/solar+PWs across the country hoping for getting installs while the Federal incentives are still available is doing enough to keep these guys busy. In my area I heard there were 5 install teams working 6 days a week and staying fully booked. We had a 3-team doing our PW/equipment install and I think 6 on our solar team. One of our advisors said he had over 500 customers he was working with so apologized for any delay responding to calls or emails we might have sent. So really doubt anyone will get to directly speak with a designer.
I will say we have had a good response from Tesla getting back to us with questions. Sometimes got right through, otherwise within a day or two, and on a few occasions early on in the planning stage, within the week. I’d say most of our phone calls to get through and waiting on hold were 15 minutes or less, a few much longer. If you’re expecting immediate responses however or a different level of communication, like with design team directly, then a smaller firm with fewer customers might be the better route for you. That’s where they can shine if they are a good company. With Tesla you have a large growing base of customers orders and lower prices due to scale, but only so many employees to handle the influx of orders.
