Thought this might be of interest to some.
When you get your "It's time to finalize your order" email there will be a check box asking if you'd like to be contacted by SolarCity for charger installation. I checked "No" because I knew I lived in an area that SolarCity does not serve.
Somewhere along the line I had an email from someone with Tesla in response to a question about when the HPCs would be shipped out so I could coordinate my electrical hookup and such. He asked if I'd checked the above mentioned "Solarcity" box. When I said "no" he asked if I'd like him to contact them for me to see if they would service my area. I said "sure".
So, eventually I got a call from Solar City just making contact and telling me they were working on providing service in my area. Got a couple more calls over the next two weeks when they finally told me that they'd partnered with Mr.Electric to provide charger install service in my area. Mr.Electric called me today and will be coming to do a survey next week.
So, while SolarCity will not be providing service or PV install option, it's still worth ticking that box as they'll help you get in touch with someone to give you an estimate for install of your HPC. I'll report back when I have their estimate...it will be interesting to compare to my 2 prior estimates.
