Elon Musk’s SolarCity trial day 1: Arguments, quotes, and testy exchanges
As he faced a lawsuit from Tesla shareholders about the SolarCity acquisition in 2016, Elon Musk was firm in the notion that he didn’t have any sway over the company’s board when it approved the deal. Musk highlighted this point on Monday, as he testified in a Delaware courtroom as part of a lawsuit filed by Tesla shareholders, who alleged that both the CEO and the company’s board breached fiduciary duties when they decided to acquire SolarCity.
When SolarCity was acquired by Tesla, Musk was the chair of the company and its largest shareholder. The CEO later noted that the acquisition was a “no brainer,” and it was completed with over 85% of TSLA shareholders voting in favor of the deal. Considering Musk’s ties to SolarCity and the solar installer company’s financial fluctuations at the time, however, critics argued that the deal was essentially a bailout. Musk was also accused of vowing retaliation against any Tesla director who voted against the acquisition.
According to Musk, Tesla’s now-Chairwoman Robyn Denholm was the one who set the final price of the deal, as well as the terms of the SolarCity acquisition. Musk noted that he was kept abreast on the basic progress of the deal, but he was otherwise recused. The CEO also stated that the notion of him controlling Tesla shareholders was implausible. “I don’t think it’s possible to control” big institutional investors like Fidelity and T. Rowe Price,” Musk said.
Things heated up when Musk started responding to questions from Randy Baron, the plaintiff’s lawyer who had already traded barbs with the CEO in the past. From the start, Baron gave Musk “fair warning” that “we have a long way to go,” and that his questioning would probably take all day and well into Tuesday. Musk joked, stating that he could tell the questioning would be long due to the size of Baron’s binder.
As part of his cross-examination, Baron showed a slide showing how far below forecasts was the amount of solar energy Tesla has deployed since its acquisition of SolarCity, especially as the solar provider was one of the US’ most dominant players in the residential solar market before it was integrated with the EV maker. Musk responded that 2017 to 2019 were the “three hardest years of (his) entire career” and that he was working hard to save Tesla at the time. After this, the pandemic shut down government permitting offices, which was a challenge to the US residential solar market. When Baron warned him that things would be really slow if Musk kept elaborating on his answers, the CEO noted that “some of your questions are tricky and deceptive.”
Musk and Baron’s exchanges only got more heated as the day wore on. When Baron asked Musk if he ever “rage fired” anyone or treated people with derision, the CEO noted that he gives “clear and frank feedback which may be construed as derision,” but he did not “rage fire” anyone. The lawyer then played several clips of Musk’s deposition showing his tense exchanges with the CEO. “That was openly derisive not for some benefit of Tesla, but because you didn’t like what was happening, correct?” Baron asked in an apparent attempt at provoking Musk.
Musk later said that he does not respect Baron because he worked for Milberg Weiss, a law firm whose partners were imprisoned for paying kickbacks to expert witnesses and plaintiffs; and Robbins Geller, whose partners also ended up incarcerated. “You were mentored by criminals. Then you continued to be mentored by criminals and that is why I do not respect you… I have great respect for the court, but not for you. I think you are a bad human being,” Musk said, later accusing Baron of being a “professional bully” who used his words to cut. “That’s very sad,” the CEO remarked.
Other loaded exchanges between Musk and Baron happened after the lawyer asked the CEO if he does not like it when people tell him what to do. Musk calmly responded that this was not exactly the case. “In fact, if I’m not mistaken, I view critical feedback as a gift,” Musk stated. This point could be confirmed by Musk’s reception to critical feedback from automotive veteran Sandy Munro, who heavily criticized the Model 3’s design in a teardown. Musk also added that if it were up to him, he would rather just work as an engineer.
“To be honest, I don’t want to be the boss of anything. I won’t want to be CEO. I tried not to be CEO of Tesla, but I had to, or it would die. I rather hate being a boss. I’m an engineer,” Musk said.
Amidst Musk’s exchanges with Baron, however, the CEO’s point was clear. SolarCity, like any aggressive startup in a high-growth industry, had a tendency to have negative cash flow. Musk noted that Amazon was an example of this, and so was Tesla, and yet, both companies are thriving now. Simply put, the CEO argued that SolarCity’s financial strains when it was acquired were not out of the norm, as even Tesla was in the same place at the time, and if needed, the solar company could have just raised capital.
“Daring enterprises burn cash and take risks to achieve something worthwhile, or even great. Tesla was subject to those risks as much as SolarCity was, but that doesn’t mean they weren’t both worthy ventures. So can’t we acknowledge that even my once-stumbling solar efforts are starting to bear fruit?” Musk noted.
The first day of Elon Musk’s SolarCity trial was adjourned until 9:15 a.m. ET on Tuesday. The CEO is expected to continue his cross-examination with the plaintiff’s lawyer.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.

Tesla updates Cybertruck owners about key Powershare feature
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
