Perhaps that's where I went wrong - I should have redrawn the layout for them.
I don't know whether the Project Advisors become more useful after the design phase, but I personally think Tesla would have a better process all around if they just cut out the middle man Project Advisor.
Since tesla has a strong software capability. my suggestion to Tesla would be to develop a collaborative software workflow allowing the customer to share design options directly with the Design team and get feedback and alternative options back from the Design team. i.e. Let the customer move around the panels on an interactive diagram like this Aurora picture below (provided by the installer I used in the end). The great things about Aurora are:
- It has up to date aerial imagery (more up to date than google maps for my property at least)
- It shows which roof surfaces provide the most sunlight
- It can estimate your first year system kWh output and lifetime output
Ideally the program would eventually be sophisticated enough to only allow panel locations that were code compliant.
