A Tesla Megapack is powering a large housing factory completely off-grid in Patterson, California, with energy from a large array of on-site, PVGraf solar panels. The factory isn’t connected to the local power grid, and this is the first time a Tesla Megapack has been deployed and running completely off-grid. The system has been operating without any issues since November.

S2A Modular, a tech company that manufactures modular homes, tiny houses, and more that run on direct-current (DC) power, owns the Tesla Megapack, and its president and cofounder, John Rowland, granted Teslarati an exclusive interview. The company is also in the business of addressing housing for the homeless as well as making luxury homes and single-family homes.

John Rowland, S2A Modular’s president, and cofounder, granted Teslarati an exclusive interview. He shared with Teslarati that the company has 35 facilities, with five currently under construction and Tesla Megapacks on order. The first one in Patterson, California, is completely off the grid, and John has been working with Tesla to monitor its progress.

The delivery and installation of the Tesla Megapack, John explained, was “very smooth.” All of the infrastructure was in place, and it only took a couple of days to install the battery.

John told Teslarati that the reason why he went with Tesla is that he is a huge fan of both Tesla and Elon Musk. Initially, he had planned to buy the Tesla PowerPacks but by the time the factory came to fruition, Tesla Megapacks were available. As a homebuilder, he wanted to build homes that run on batteries. John said that engineered and built the second off-grid Tesla-powered home in North America.

“When I built that home, I decided I wanted to scale and build homes that were meant to run on batteries because this is how that house was engineered and built. It was the lowest voltage, lowest amperage home on the planet.”

John realized that in order to scale, he would need a factory and wanted to take the same approach that he has taken to engineering and building the homes and “engineer and build a factory that was made to run off-grid.

The hundred thousand-square-foot factory has no gas, or propane, only graphene solar panels, and a Tesla Megapack. “And no connection to the electrical grid.”

John pointed out that he has had a good relationship with Tesla since 2015, and once the Megapacks were available, he ordered one for each of the facilities.

“We’ve got the first one in Patterson, California, and it’s been up and running a little over a month now. And it’s running like a champ. The whole factory’s powered off-grid, and it’s a huge success, so we’re looking to carry it over to our next facilities.”

John and his team and Tesla are monitoring the battery three times a day since it is completely off-grid. At first, there was a little hesitation on Tesla’s part for installing a completely off-grid Megapack, but John was able to win them over, and things are going smoothly.

“This is the first time that a Megapack was programmed to run off-grid. They’re set to take a trickle charge from the grid 24/7, and it took some convincing to get Tesla to allow us to do it this way. At first, they said, ‘you’re a couple of years ahead of us,’ but they finally agreed to allow us to do it, and now they’re using it as beta. They’re monitoring it just like we are.”

“One of Tesla’s head engineers that we work with told us that when we powered it up, it would take four days for our solar to charge the battery fully. We did it in seven and a half hours.”

John explained that the solar panels his company uses are made with specially manufactured graphene solar panels. “They’re the only company in the world using graphene, and they have 20 worldwide patents on it. At S2A, we paid and file our own UL( Underwriter Labs) to have our own UL-rated panel produced.”

When asked about feedback, John explained that he talks to Tesla’s engineers regularly and provides updates on the battery’s performance.

“It’s quite to our surprise It’s a 1.4-megawatt battery, and we’re able to keep it about 90% even with all of our equipment running. It’s really working better than our expectations.”

One thing John wasn’t expecting was the surplus of energy. He actually plans to connect the Megapack to the grid next year so that he can discharge the excess power and help take some of the burdens away from the local grid.

“Our inverters are shutting off every day because we’re producing more power than we can use. Our factory is actually net-positive, and we will start contributing back to the grid next year.”

“We’ve got the battery set right now–when it reaches 97% capacity, the inverter shuts down and stops producing power. We’ve been monitoring it three times a day, and it’s been shutting off every day. Even with the factory running at full speed, we still produce excess energy.”

John added that he also purchased the Tesla Semi and plans to use them to deliver homes to customers.

Disclosure: Johnna is a $TSLA shareholder and believes in Tesla’s mission.

Tesla appears to have teased a long-awaited Model Y trim for a launch on Friday.

The company posted it with its Europe & Middle East account, and it appears to be a Model Y Performance, which has been spotted testing at the famed Nurburgring in Germany.

The Model Y Performance became a big-time hit after it packed the family-style interior with lightning-fast acceleration, speed, and handling.

As Tesla transitioned the Model Y into the updated “Juniper” design, the company took its time to create an even better vehicle with the new Performance configuration.

It has surely taken its time, but the vehicle appears to have undergone some exterior changes to enhance aerodynamics, handling, and overall performance.

We recently went into what was different about the test units spotted at Nurburgring in an article, but we’ll also list them here:

  • New 21″ wheels
  • All black headliner, a big change that was included in the Model Y L, the first time a Model Y has had that option
  • Updated brakes
  • Bucket seats that appear to be similar to the new Model Y L in China
  • New Carbon Fiber Spoiler
  • Performance Badging
  • Changes to both the front and rear bumper
  • Suspension with Adaptive Dampers

Tesla Model Y Performance zips around Nurburgring with new features

It does not seem like there’s much else it could be, but it is important to note that Tesla has been developing a handful of affordable models. There is a possibility that Tesla could launch one of these on Friday, but it seems unlikely.

The affordable models will likely be coming to the United States or China before they would in Europe.

They would be developed at Gigafactory Texas or Gigafactory Shanghai. The company stated in its Q2 Earnings Shareholder Deck that it had continued to expand its vehicle offerings and successfully manufactured the first builds of a more affordable model in June.

Volume production is planned for the second half of 2025.

SpaceX Starship Flight 10 was so successful, it’s breaking the anti-Musk narrative

That’s all the proof one could need about the undeniable success of Starship Flight 10.

Starship Flight 10 was a huge success for SpaceX. When both the Super Heavy booster and the Starship Upper Stage successfully landed on their designated splashdown zones, the space community was celebrating.

The largest and most powerful rocket in the world had successfully completed its tenth test flight. And this time around, there were no rapid unscheduled disassemblies during the mission.

As per SpaceX in a statement following Flight 10, “every major objective was met, providing critical data to inform designs of the next generation Starship and Super Heavy.” The private space enterprise also stated that Flight 10 provided valuable data by stressing the limits of Starship’s capabilities.

With all of Flight 10’s mission objectives met, one would think that it would be pretty easy to cover the story of Starship’s successful tenth test flight. But that’s where one would be wrong, because Elon Musk companies, whether it be Tesla or SpaceX or xAI, tend to attract negative slant from mainstream media outlets.

This was in full force with Starship Flight 10’s coverage. Take the BBC’s Facebook post about the fight test, which read “Elon Musk’s giant rocket, earmarked for use in a 2027 mission to the Moon, has had multiple catastrophic failures in previous launches.” CNN was more direct with its slant, writing “SpaceX’s troubled Starship prototype pulls off successful flight after months of explosive mishaps” on its headline.

While some media outlets evidently adopted a negative slant towards Starship’s Flight 10 results, several other media sources actually published surprisingly positive articles about the successful test flight. The most notable of which is arguably the New York Times, which featured a headline that read “SpaceX’s Giant Mars Rocket Completes Nearly Flawless Test Flight.” Fox News also ran with a notably positive headline that read “SpaceX succeeds at third Starship test flight attempt after multiple scrubs.”

Having covered Elon Musk-related companies for the better part of a decade now, I have learned that mainstream coverage of any of his companies tends to be sprinkled with varying degrees of negative slant. The reasons behind this may never be fully explained, but it is just the way things are. This is why, when milestones such as Starship’s Flight 10 actually happen and mainstream media coverage becomes somewhat objective, I can’t help but be amazed. 

After all, it takes one heck of a company led by one heck of a leader to force objectivity on an entity that has proven subjective over the years. And that, if any, is all the proof one could need about the undeniable success of Starship Flight 10.

Tesla’s Elon Musk takes another shot at Waymo’s capabilities stemming from LiDAR

“LiDAR also does not work well in snow, rain or dust due to reflection scatter. That’s why Waymos stop working in any heavy precipitation.”

Tesla CEO Elon Musk has frequently expressed his opinions on LiDAR in the past, but in recent days, the EV maker’s frontman has continued to discuss the weaknesses in the technology and why his company has relied on cameras.

He also mentioned the suite’s limits on Waymo’s capabilities.

Tesla completely abandoned using radar alongside its camera suite a few years ago, something it referred to as “Tesla Vision” at the time. For its vehicles, it has only used cameras since this transition, and Musk has never once shied away from this strategy.

Earlier this week, he discussed the reliance of LiDAR and radar by other companies:

“Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins?

This sensor ambiguity causes increased, not decreased, risk. That’s why Waymos can’t drive on highways.

We turned off radars in Teslas to increase safety. Cameras ftw.”

Elon Musk argues lidar and radar make self driving cars more dangerous

He continued with this narrative again and mentioned Waymo specifically on a second occasion.

Musk’s focus this time was on Waymo vehicles and their capabilities in adverse weather, specifically snow, rain, or even dust storms, and how LiDAR struggles to navigate in these conditions.

He said:

“LiDAR also does not work well in snow, rain or dust due to reflection scatter. That’s why Waymos stop working in any heavy precipitation. As I have said many times, there is a role for LiDAR in some circumstances and I personally oversaw the development of LiDAR for the SpaceX Dragon docking with Space Station. I am well aware of its strengths and weaknesses.”

Tesla’s approach is significantly different than most companies. Waymo, Motional, Aurora, and Zoox all use LiDAR for their self-driving programs, while Tesla continues to rely on its camera-only approach.

Musk even said that Model S and Model X utilized a Tesla-developed high-resolution radar, but it could not “compare to passive optical (cameras), so we turned it off.”
