Precisely. There is no other company like Tesla with it's success in EVs.
There are 100s or even 1000s of solar companies all around the world. What happens to SCTY is largely irrelevant to climate change or any other greater good.
Solar will win on it's own, with or with out SolarCity's help.
That's not the case with EVs and Tesla.
Only partially true. After SCTY consolidated with Tesla, SCTY will be one of the most cost effective (if not the most cost effective) in the entire solar market in terms of costs at sales, installation, maintenance. Even the hardware cost (solar panel, battery) will be lower because the design will be more integrated and eliminate redundant hardware. Customer satisfaction will be a lot higher as well because there is only one place to buy all you need, one place of contact, and one visit for all installation. Rather than going back and forth between solar panel installer, battery installer, EV charging installer, and the EV company.
Keep in mind that the cost of installing solar panel on roof are increasing dominated by cost of installation, cost of labor, cost of paper work (permit), cost of sales etc. The costs of solar panel itself is no longer a dominant factor. That's why Elon is doing this to lower the overall cost of the installation, in order to dramatically increase solar installation around the world. I don't think other solar installers can lower the overall cost as much because they just don't have the kind of consolidation and synergy that I mention here.
The addressable market of customers are the same as well. As mentioned in Tesla press release, the type of people buying Tesla EV will most likely buy solar, and vise versa. Tesla is basically increasing the revenue per physical store if they are also selling solar. In addition, the Tesla brand is just a LOT more well known than SCTY or any solar company out there. Unless you are a green enthusiast, chances are you never heard what the heck is SolarCity or Sunpower, or understand the solar industry in general. But a lot of the general public would have heard about Tesla by now. Also, the Elon Musk "halo" effect are generally associated with Tesla and SpaceX in the general public, while most of them won't associate Elon with SolarCity. Many people buy into the Tesla brands coz of Elon himself. Putting SolarCity under the Elon "halo" effect will help solar industry for sure. In short, Tesla merging with SolarCity will create tremendous synergy in terms of cost, ease of implementation, customer satisfaction, and brand recognition. And it will make execution a lot easier for both Tesla and SolarCity, NOT harder, like Elon have stated couple times in the conference call.
For all the naysayer out there, have you guys even listened to the conference call, or even try to understand Elon's point of view?
