Tesla has been gradually deploying a massive set of solar panels on the roof of its Gigafactory in Austin, Texas, set to be the world’s largest upon completion, according to one person from the company.

During a Travis County Commissioners Court meeting this week, Tesla’s senior manager of factory engineering, Logan Grant, told county officials that Phase 1 of the solar array had been completed, according to a report from the Austin Monitor. When it’s complete, Grant says, the system will be the world’s largest solar rooftop installation, with roughly 30 megawatts of power.

“We finished phase 1, so we can pull roughly 10 megawatts. When it’s all said and done, it will be 30 megawatts, which will be the largest rooftop solar I think in the world,” Grant said during the presentation.

According to Grant and other Tesla officials, the roof will include roughly 70,000 total rooftop solar panels across the 10 million square foot factory. The company has used dark-colored solar panels to outline the word “Tesla” on the Giga Texas roof, and the word has already started taking shape despite the project not yet being completed.

Satellite photos taken from space show the solar roof project, which has notably made quite a bit of progress since the factory first began working on it.

Tesla Giga Texas’ solar panel installation and start of operations imminent: report

You can see a few side shots of Tesla’s solar roof installation project at Giga Texas in the latter part of Joe Tegtmeyer’s video taken earlier this week.

Currently, Tesla produces the Model Y SUV at Giga Texas, and the automaker is also producing the forthcoming Cybertruck at the location.

Tesla is also expanding the Giga Texas production facility to include electric vehicle (EV) battery production and cathode manufacturing, as pointed out by the automaker’s senior global director of public policy and business development, Rohan Patel.

“The first American battery manufacturing at scale is happening here and the first American cathode manufacturing – which is the most expensive part of the battery – is happening at Giga Texas,” Patel said during the presentation.

The automaker is currently working on Phase 2 of the facility’s 4680 battery cell facility, which is expected to add four more production lines by the latter part of 2024.

Tesla reveals its first Semi customer after launch

Tesla revealed its first customer for the all-electric Semi truck after it launches next year. Who it truly is should not be a surprise.

The Semi is going to finally start deliveries to new companies outside of Tesla’s pilot program starting in 2026. The company has been building a dedicated production facility in Reno, Nevada, that has finally taken shape, but Tesla was evidently not finished with the Semi’s development.

Tesla shares rare peek at Semi factory’s interior

Last week at the Annual Shareholder Meeting, Tesla said it had implemented some new designs into the Semi, helping with efficiency, updating its design, and making it a more suitable vehicle for hauling loads, as the changes also helped increase payload.

Tesla has obtained a lengthy list of companies that have committed to implementing the Semi in their own fleets, hoping to bring their logistics lineups up to date with electric powertrains and autonomous technologies.

While it is already operating a pilot program with PepsiCo. and Frito-Lay, Tesla will expand to other businesses, primarily using it internally after its launch.

Head of the Semi program at Tesla, Dan Priestley, said the company would be the first user of the vehicle after its launch next year. It has been using it to a certain extent, but the company has not been able to completely abandon gas haulers.

Instead, it will implement the Semi into its fleet for more sustainable vehicle logistics starting next year:

Tesla has already received orders for the Semi from a variety of large companies, including Walmart, Sysco, Anheuser-Busch, UPS, DHL, J.B. Hunt, among others.

Many analysts see the Tesla Semi as a major contributor to future growth and increasing value within the company, especially from a Wall Street perspective. Some firms say the Semi is one of several near and medium-term contributors to the company increasing its market cap.

Cantor Fitzgerald is just one of those firms, as last week it explicitly listed the Semi as a catalyst.

Analyst Andres Sheppard said, “Overall, we remain bullish on TSLA over the medium to long term. We continue to see meaningful future upside from Energy Storage & Deployment, FSD, Robotaxis/Cybercab, Semis, and Optimus Bots.”

Tesla China rolls out Model Y L V2L adapter, and it’s free for early owners

Tesla China has released a useful new accessory for the Model Y L, and it is free for some owners. With the accessory, the Model Y L effectively becomes a giant power bank that owners can use to power appliances when they are camping, or if their homes are hit by a power outage. 

Tesla Model Y L V2L adapter

Tesla China announced the rollout of the Model Y L’s AC external power adapter on social media platforms such as Weibo. As per the product’s advertisement, the Model Y L could provide up to 2,200W of power with its adapter, allowing it to support numerous appliances on the go. Of course, but could also be used to charge devices during power outages. 

Tesla China notes that the adapter’s current is 220V, and it also features an IP44 protection grade. Tesla notes that the adapter could operate at temperatures between -30℃ ~ +50℃. The Model Y L’s V2L functionality would not work if the vehicle’s battery is less than 10%, however. 

Tesla China’s official shop is selling its AC external power adapter for a reasonable price. The product could be purchased for RMB599, which is equivalent to $85. That’s a great price for an accessory that could make car camping sessions several times more convenient.

Free for early Model Y L owners

While the Model Y L’s AC external power adapter is priced reasonably at the Tesla China shop, the accessory is available for free for early owners of the extended wheelbase six-seat all-electric crossover. This was highlighted in a message that Tesla China reportedly sent to owners of the vehicle.

“Your Tesla account is eligible for a free Model Y L dedicated AC external power adapter. Please log in to the online store to add the adapter to your cart. Once the system verifies it correctly, the price will automatically change to 0 yuan before placing the order. We will send it to you via express delivery subsequently. 

“This free qualification is only for the first owner of the Model YL who did not receive an AC external power adapter at pickup, valid until February 28, 2026. Failure to place an order upon expiration will be considered as a waiver of eligibility. If there is a temporary shortage of goods, please be patient and we will reschedule the replenishment by the end of January 2026,” Tesla China wrote.

Tesla Cybertruck and Model 3 program manager steps down

The now-former executive played a central role in several of Tesla’s key milestones.

Published

Siddhant Awasthi, Tesla’s Program Manager for the Cybertruck and Model 3, has announced his departure after eight years with the company. Starting as an intern, Awasthi played a central role in several of Tesla’s key milestones, from the ramp-up of the Model 3 and Giga Shanghai to the launch of the long-awaited Cybertruck.

From intern to program leader

In a social media post, Awasthi described leaving Tesla as “one of the hardest decisions” of his life. He credited CEO Elon Musk, Tesla’s leadership team, and his colleagues for helping turn ambitious ideas into tangible vehicles. During his tenure, Awasthi contributed to Tesla’s global expansion and the evolution of its vehicle electronics and wireless systems, culminating in the Cybertruck’s long-anticipated rollout in late 2023.

He noted the intensity and innovation of his Tesla years, calling the experience “a thrilling journey” that shaped his career before the age of 30. “It’s been an absolute privilege,” he wrote, adding that working with “rockstar colleagues” made even the most demanding days worthwhile.

Tesla’s leadership transitions

Awasthi’s departure comes as Tesla continues to scale global operations and prepare for major product updates, including next-gen vehicle platforms and software-driven improvements. Despite stepping away, Awasthi voiced confidence in Tesla’s future. “I’m confident Tesla will nail its next big mission,” he said, highlighting his belief in the company’s capacity to deliver breakthrough products and improve safety for drivers worldwide.

“This decision wasn’t easy, especially with so much exciting growth on the horizon. Tesla vehicles are incredibly complex systems that often don’t get the credit they deserve, but I’ve witnessed firsthand how they’ve changed lives—for our customers, my friends, and my family—adding real value and, above all, improving safety. I’m confident Tesla will nail its next big mission (especially after last week), and I’m truly excited for the next chapter of my life,” the former Tesla executive wrote.
