This is great news! I've been hoping they do something like this. This was a sore point for the wealthy people buying Roadster, Model S & Model X before, so cleaning this up a bit will be very welcome for the more mass market Model 3. Before, it was a few thousand dollar annoyance for people used to dealing with contractors and few thousand dollar annoyances; now, with cheaper mass market cars and the people buying them, they have no idea how to hire contractors often, and many of them would consider "a few thousand dollars plus or minus" to be an amazingly huge amount of money. This is the last possible moment Tesla can pick to fix up this side of their business to avoid widespread hurt, and it's about time, but I'm glad they're actually doing it.
So, that is $1,000 in addition to the cost of the charger? No thanks, I can get a licensed electrician who has done a few already to do it for $200.
Every building is different. There's often complications. The usual cost is probably closer to $600, and so all of those cases where it turns out to be more like $1,200, Tesla just pockets the difference from the $500 installs and covers the $1,300 installs and so on. It's kind of a one size fits all install price. Or, trying to save about $400, you can spend about $300 worth of your time hunting around looking for electricians, and maybe get someone that might know what they're doing maybe, and take another $200 day off and maybe get fired to be there when they're there so you can try to explain to them how this electric horse works with an electric tail. Your luck is all the electricians in the area hate Tesla. This option available straight from the company is a fantastic idea.
They can roll it into any other services they're also installing, like solar and PowerWall. One contact point. They mentioned this years ago in shareholder conference calls. They're actually doing it, is the message I'm getting from this, in little bits and pieces. Let's go Tesla! Get the whole thing rolled up into one contact point and make this work.
