I thought it would be a good idea to see how many Powerwalls have been installed over the past year so I created this simple poll. It will also be useful to see if Tesla is increasing or decreasing deliveries of Powerwalls over this period. It doesn’t matter what company installed the Powerwalls for this poll, nor does it matter how many Powerwalls were installed. Thanks for your participation.
Though for me it's installation, not activation. It was installed late January, but I'm still waiting to start the clock for PTO, since this week's final inspection on the solar failed and the next available inspection appointment with the city was April 10th. It did get commissioned yesterday, however, so the green bar on the side has finally gone from blinking to solid, and its webpage now shows energy flowing from the grid to my house, just nothing to/from the PW and nothing from the solar. Oh, and it was making all sorts of noises last night, from the outside you didn't really hear anything but the fan, but inside I think it tried every frequency possible (randomly), as if it was looking for the resonant frequency of my wall.
