Elon Musk, on March 9th of this year, promised via a tweet that he could deliver this battery within 100 days – or it’d be free.

As we reported on Friday, local Reno media outlets were given rare access to the Tesla Gigafactory and we even got our very first glimpse of the manufacturing floor. Though reporters were not allowed to take footage of the assembly line and it looks like all pictures were from the same angle near the offices.

Now it appears that someone with better access leaked several pictures of Tesla’s Powerwall and Powerpack assembly line, and it’s awesome. expand full story

Last week we reported that SolarCity more than doubled its battery pack business with Tesla Energy in 2015 versus the previous year, and the trend is set to continue as the solar installer confirmed today that it selected Tesla’s energy division to supply its massive energy storage project on Kaua’i Island in Hawaii.

We reported on the project last year when SolarCity announced its power purchase agreement (PPA) with Kaua’i electric utility (KIUC) for two 12 MW solar arrays and their intention to install 52 MWh of energy storage. expand full story

SolarCity published its earnings for the fourth quarter and full year 2015 yesterday.

On a more positive note, we learn from the company’s SEC filing that it more than doubled its battery pack business with Tesla Energy in 2015 versus the previous year, despite the market for home energy storage only being in its infancy. expand full story
