This seems in large part to reflect their expansion in to battery and solar technology following the aquision of SolarCity. However, I wonder when products such as SolarRoof and Powerwall 2 will be become available. When I read/viewed the promotional material for those products I got the impression that they would be "hitting the shelves" early 2017. Perhaps I was mistaken. The Powerwall 2 order page[1] used to read "Installations begin in January 2017." I just checked back and it now reads "February 2017." On March 1, will it change to "March 2017?" I am a very serious potential customer (dad needs help ordering a power backup solution for his medical devices) and sent a detailed email asking for more information. I didn't want to put down a deposit without more details about whether the products are available, if my area is suitable, and when installation would start ("January - no, February - no, March - actually, check back this summer" wouldn't be acceptable for my use case). I didn't hear back for a few weeks. I just followed up again. Hopefully they respond this time, but I would imagine that I am probably going to go with another battery backup solution (or a gas-based generator solution) at this point.
