The vision for the Buffalo factory looks like this: jobs ramping up and solar panels being affixed to homes throughout the country. That vision has been slow in materializing.

Give the company this much credit: It is looking for diversified products until its state-of-the-art solar roof panel is ready. It has started making electrical components for the latest version of its electrical vehicle Supercharger in Buffalo and, as has been reported in this newspaper, the first production line for the Supercharger cabinet is operational. Additional lines are scheduled to be installed later this year.

In addition, the company has added several production lines to support creating other electrical components that are used in its Powerwall and Powerpack batteries.

Jonathan Chang, the assistant secretary at Tesla’s Silevo subsidiary, in a letter to state officials said: “This expanded in diversified product manufacturing further brings the RiverBend facility into the full ecosystem of solar, energy storage, electrical vehicle and other Tesla product offerings.”

It sounds good. But as that long-ago famous Wendy’s commercial asked: “Where’s the beef?” Shareholders want to know, as Tesla recently started trading below $200 for the first time in more than two years.
