It has been over 6 months since I put in my deposit and like others here haven't heard much from Tesla. I've recently discovered a Tesla certified installer in CO who has given me an estimate. It differs substantially from Tesla's direct estimate. Lower in power output (8.5KW Vs 14.3KW) but almost the same in price. I get the impression they are just starting installing Tesla roofs in CO. Do these third party installers have better access/priority to Tesla materials? Do they provide any better service than directly from Tesla?
