Tesla will incorporate Panasonic cells into glass solar roof tiles when production begins in summer 2017
Tesla announced today that it has finalized an agreement with Panasonic that would allow both companies to begin manufacturing high-efficiency photovoltaic (PV) cells and modules from its Buffalo, NY factory. The update comes months after Tesla first announced that it had entered into a non-binding letter of intent with Panasonic under which the two companies would collaborate on the manufacturing and production of PV cells and modules. However, the agreement was only valid upon shareholders’ approval of Tesla’s acquisition of SolarCity – a deal that saw an overwhelming majority of voters approving the merger.
Tesla and Panasonic will initially build PV cells and modules for use in traditional solar panels, but will eventually incorporate Panasonic cells into Tesla’s Solar Roof product when production begins mid-2017. The PV cells will be integrated directly into the glass solar roof tiles which Tesla is offering in a variety of designs.

As part of Tesla CEO Elon Musk’s vision of the future, largely comprised of sustainable transportation and storage systems for renewable energy, Tesla’s solar products will be integrated with Panasonic cells and operate seamlessly with the company’s home and commercial energy storage products, Powerwall and Powerpack. Tesla indicates that it has plans to ramp up to 1 Gigawatt of PV module production by 2019.
Today’s announcement also reaffirms Tesla’s commitment to creating American-based jobs at Buffalo, NY, home to SolarCity’s solar factory. We had previously reported that SolarCity has begun holding workforce information sessions as the company prepares to hire nearly 1,400 workers for its $900 million solar factory located at Riverbend.
Expect to see more announcements from Tesla as it continues to fortify its long-standing partnership with Panasonic. Panasonic is an investor and strategic partner at the Gigafactory in Sparks, Nevada where it manufactures cylindrical 18650 and 2170 lithium-ion cells used in Tesla’s fleet of vehicles and grid storage products.
Panasonic has agreed to cover capital costs required at the Buffalo, NY solar factory. In exchange, Tesla will continue on its long-term purchase commitment from Panasonic, namely, an extension into the purchase of Panasonic PV cells.
Read Tesla’s full announcement below:
Tesla and Panasonic have finalized an agreement this week to begin the manufacturing of photovoltaic (PV) cells and modules at the Buffalo, NY factory. These high-efficiency PV cells and modules will be used to produce solar panels in the non-solar roof products. When production of the solar roof begins, Tesla will also incorporate Panasonic’s cells into the many kinds of solar glass tile roofs that Tesla will be manufacturing. All of these solar products will work seamlessly with Tesla’s energy storage products, Powerwall and Powerpack. Production of the first PV modules will begin in summer 2017, and will ramp to 1 Gigawatt of module production by 2019.
As Tesla and Panasonic begin production, Buffalo will continue to expand Tesla’s American manufacturing base and create thousands of new jobs in the coming years. Tesla reaffirms SolarCity’s commitment to create over 1,400 jobs in Buffalo—including more than 500 manufacturing jobs. Panasonic, with its technological and manufacturing expertise in PV production, will also work with Tesla on developing PV next generation technology at SolarCity’s facility in Fremont, CA.
As part of the agreement, Panasonic will cover required capital costs in Buffalo and Tesla is making a long-term purchase commitment from Panasonic. The collaboration extends the established relationship between Tesla and Panasonic, which includes the production of electric vehicle and grid storage battery cells at the Tesla Gigafactory.

Elon Musk hits back at former Tesla employee who disagrees with pay package
Tesla is worth more than all other automotive companies combined. Which of those CEOs would you like to run Tesla?
It won’t be me.

Elon Musk gave a tough response to a former Tesla employee who spoke out on X about the structure of the CEO’s pay package, arguing that it is an overpayment and would not generate enough shareholder value.
Without a doubt, the biggest issue on the bill at this year’s Tesla Shareholder Meeting in November is that of the pay package that was proposed to CEO Elon Musk.
As the Shareholder Meeting approaches, Tesla is urging those investors to vote in support of Musk’s pay package. So far, the community has been overwhelmingly supportive of giving Musk his massive payday, which could give him $1 trillion in additional holdings if he completes each of the outlined performance tranches.
However, there are a handful of institutional and individual shareholders who have pushed back against the package, either because of its value or because they feel it does not benefit shareholders enough.
Last week, we reported that Institutional Shareholder Services (ISS) advised voting against Tesla’s pay package for Musk. The firm said the payday would give Musk”extraordinarily high pay opportunities over the next ten years,” and it would “reduce the board’s ability to meaningfully adjust future pay levels.”

Additionally, it called the value of the pay package “astronomical.”
On Saturday, a former Tesla employee said on X that Tesla’s proposed pay package for Musk would “barely beat inflation and it would underperform the S&P 500 considerably.” Additionally, he said:
“Sorry, Tesla, some of us (and supposedly, ISS too) simply don’t think that underperforming the S&P 500 this much is worth paying somebody 20 billion dollars worth of company value.
As a fan, I love Tesla, I want it to succeed. As a shareholder, I don’t want Tesla to over-pay for its CEO I strongly believe that the 2025 pay package proposal would over-pay for its CEO, and that other competent CEOs could grow Tesla just as much with way less political drama and cost investors much less that this proposal.”
Musk responded bluntly:
“Tesla is worth more than all other automotive companies combined. Which of those CEOs would you like to run Tesla? It won’t be me.”

It seems the worry about Musk’s potential involvement in politics still looms to many, based on the responses to Musk’s post, which frequently mention that as a downside of his last year as Tesla CEO. However, Tesla’s Board confronted that directly.
In its proxy filing after announcing the pay package, Tesla said that it had three commitments, one of which was that the company would “receive assurances that Musk’s involvement with the political sphere would wind down in a timely manner.”

Musk’s previous pay package was approved by shareholders twice, but it never made it to the CEO because of a lawsuit with the Delaware Chancery Court brought forth by a small-time shareholder.
The response from Musk does seem to show that if this time is no different, he will inevitably step down as CEO in the coming years.

Tesla rivals are lagging behind alarmingly in this crucial EV necessity

Tesla rivals are lagging behind the company in alarming fashion in this crucial EV necessity: charging.
Tesla has had a long-standing reputation for having the most expansive electric vehicle charging infrastructure, and even as other companies have launched their own as part of the vehicle manufacturing, nobody seems to keep pace with the EV leader.
A report from Paren exhibited this trend in Q3, showing that Tesla overwhelmingly dominated EV charging stall installations over the past three months. This data is based on U.S. installations, where Tesla has long held a dominating position as the leader in overall electric vehicle sales for many years.
In Q3, Tesla installed 1,820 new chargers in the United States, bringing its total presence to 34,328, an all-time market share of 53.2 percent of all charging stalls in the country.
What’s alarming is the fact that all other networks — ChargePoint, Red E, Electrify America, EV Connect, EVgo, Ionna, Blink, Pilot Flying J, and Rivian Adventure — only installed 841 chargers collectively in Q3. That is nearly 1,000 units behind Tesla, despite there being nine companies contributing as competitors.
These nine networks have 10,055 stalls in total, the data from Paren shows, accounting for 15.6 percent of the chargers in the United States.

EV charging is such a crucial part of the ownership experience, and also a part of the ongoing expansion of EV adoption in the United States.
As more people buy EVs and they become a more prominent form of passenger transportation, more chargers are needed. Many owners charge at home, but charging options in public are important to have for traveling, commuting, and for those who do not have access to residential charging.
With Tesla opening its Supercharger Network to the majority of EV brands over the past two years, things have gotten better.
It has been alarming to see so many companies involved in EV infrastructure essentially accept the gap between Tesla and themselves; not a single company has tried to up its pace to catch up to what Tesla has.
When it comes down to it, as long as there is charging, the manufacturer does not truly matter.
However, it would be nice to see Tesla have some competition in the space, but with its domination and head start in the infrastructure division, it seems the company will have this competitive advantage for years to come.

Tesla updates fans on its plans for the Roadster
Earlier in 2025, Musk said Tesla would host the “most epic demo” for the Roadster in late 2025. We’re in Q4, so time is running out, but we finally got the update we’ve been waiting for from von Holzhausen on the Ride the Lightning podcast yesterday.

Tesla has finally updated fans on its plans for the Roadster after stating earlier this year it would host the “most epic demo,” showcasing the vehicle’s capabilities.
The Roadster is amongst the most highly anticipated automotive releases in the entire industry, and was set for release in 2020 initially. However, Tesla got so caught up with scaling up the Model Y and focusing on autonomy that the project took a figurative backseat.
In the years since its planned release, we have not seen much of the vehicle. Company executives like Elon Musk and Chief Designer Franz von Holzhausen have hinted at things about it and teased us with potential release dates, but each time, it has been delayed.
Last year, Tesla planned to show something, but Musk saw what improvements had been made from the original design unveiled back in 2017 and figured the company could go a step further, only delaying the project another year.
But what’s another year, right?
Earlier in 2025, Musk said Tesla would host the “most epic demo” for the Roadster in late 2025. We’re in Q4, so time is running out, but we finally got the update we’ve been waiting for from von Holzhausen on the Ride the Lightning podcast yesterday.
Confirming the demo was still on for this year, he also teased some new features that the Roadster will have, like new paint options.
Von Holzhausen said:
“I’m excited to showcase the Roadster for a lot of different reasons. The wait will be worth it.”
Additionally, he said the capabilities of the Roadster are truly something, and they have gotten the vehicle to a point that it seems to test the “limits of physics.” Franz added that Tesla has “really gotten to a point where we are going to be achieving that standard that we set out.”
Obviously, the Roadster is not a major contributor to Tesla’s mission or to its future, which mostly leans on artificial intelligence and Robotaxi or autonomy. However, it is still a product that Tesla needs to offer, as many have put massive $250,000 downpayments on the vehicle in an attempt to purchase one.
Tesla has not yet announced a date for its demo of the Roadster, but based on Franz’s interview, it seems the company is still on track to hold that by the end of the year.
