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.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters
The Space Force just handed SpaceX $2.29 billion to build the military’s space internet backbone.
The U.S. Space Force awarded SpaceX a $2.29 billion contract on May 26, 2026 to build the backbone of its Space Data Network, a satellite-based communications system designed to keep American military forces connected anywhere on Earth in real time. The contract is firm-fixed-price and requires SpaceX to deliver a fully operational prototype by the end of 2027.
In plain terms, the SDN Backbone is the plumbing behind the military’s space-based internet. It functions as a low Earth orbit satellite constellation providing robust, high-capacity, and low-latency data transport for the Joint Force, connecting sensors and weapons systems continuously, globally, and securely. Think of it as a private, hardened version of Starlink built specifically for battlefield communications, one that soldiers, ships, and aircraft can rely on even in contested environments where ground-based networks have been disrupted.
SpaceX is quietly becoming the U.S. Military’s only reliable rocket
The Space Force was direct about why SpaceX was selected. “The SDN Backbone leverages the best of commercial innovation and delivers a strong foundation for the SDN mission set — a huge benefit and enabler for our warfighters,” said USSF Col. Ryan Frazier.
“We aren’t trading speed for scale; we are demanding both. By using rapid prototyping and Other Transaction Authorities, we are ensuring our advanced solutions are integrated and delivered to the warfighter as fast as possible,” added USSF Lt. Col. Fry, SDN Backbone system program manager.
The SDN Backbone will work alongside the Space Development Agency’s Transport Layer, with the two systems forming a unified open architecture to provide critical data transport for current and future Department of War missions.
As Teslarati has reported, this is not SpaceX’s first Space Force contract of 2026. In April, the Space Force awarded SpaceX $178.5 million to launch missile tracking satellites, and SpaceX is already embedded in the Golden Dome missile defense software group. The $2.29 billion SDN Backbone award puts SpaceX at the center of how the American military communicates in space, a position with direct implications for its reported $1.75 trillion IPO valuation as the company heads toward a public offering as early as June 2026.
Tesla’s dedicated factory for building up to ten million Optimus units is officially under construction at Gigafactory Texas.
Drone footage released on May 27 by Giga Texas observer Joe Tegtmeyer captures the significant milestone of the first steel structure officially standing at Tesla’s new Optimus factory on the North Campus of the facility.
Phase two of land reclamation is advancing steadily, and the progress will let the new building extend nearly the full length of the main Giga Texas factory, potentially exceeding 4,000 feet, while measuring somewhere between 50 and 70 meters narrower. Extensive foundation work is proceeding as well.
Big news at the new Optimus 10m/y factory construction site today! The 1st steel structure has been erected & as expected the second phase of land reclamation is underway.
This will allow this new factory to grow to nearly the same length as the main Giga Texas factory,… pic.twitter.com/FidRLV6XpU

This facility forms a central element of Tesla’s broader North Campus expansion at Giga Texas. The project will add more than 5.2 million square feet of new industrial space. It sits alongside other advanced developments, including a Terafab for next-gen AI chips. The scale reflects Tesla’s commitment to transforming humanoid robotics into a core pillar of the company’s future.
Musk has said that Optimus will be the biggest product in the world on several occasions. He believes it will be Tesla’s biggest valuation contributor.
Tesla prepares to expand Giga Texas with new Optimus production plant
Tesla plans to build about 10 million robots at the site annually once it is completed, which would be about 27,000 units each day.
The Optimus plant at Giga Texas is part of Tesla’s phased strategy for Optimus manufacturing. In an effort to start production of the robot well before the Giga Texas plant is complete, Tesla ended production of the Model S and Model X vehicles, which were built in Fremont, California, to make way for initial Optimus manufacturing efforts.
Production there will start in either July or August of this year, and early units will support internal factory tasks while the team gathers real-world data to refine processes. The Gigafactory Texas facility will house a second-gen production line. It targets high-volume output starting in Summer 2027.
Musk has repeatedly described Optimus as potentially more valuable than Tesla’s entire vehicle business. Current versions are already completing minor tasks around various facilities, while Tesla continues to refine its abilities and add new features.
Tesla’s total investment could reach several billion dollars. Significant challenges lie ahead, including the creation of an entirely new manufacturing ecosystem, the refinement of AI systems for dependable autonomy, and the development of reliable supply chains for actuators, sensors, and other components.
Nevertheless, the visible progress at Giga Texas highlights Tesla’s capacity to translate ambitious concepts into physical reality.
Tesla’s Optimus factory stands as much more than a simple expansion project, as it is quite literally the second phase of what could potentially be the biggest product ever. With construction beginning, 2027 is poised to become a transformative year for Tesla, as it evolves even further from an electric vehicle leader into a pioneer of intelligent, general-purpose machines.
Tesla Vice President of Vehicle Engineering, Lars Moravy, recently revealed the company has thought about introducing a Plaid powertrain on the Model 3, but there could be some challenges involved.
On the Ride the Lightning podcast, Moravy revealed that he thinks about a Plaid Model 3 “all the time,” and it certainly has a place in Tesla’s potential lineup of future vehicles.
Now that the Plaid powertrain is technically defunct due to the newfound absence of the Model S and Model X, Tesla could find a way to reintroduce the lightning-quick trim level to its mass-market vehicles.
But there are going to be some challenges with it. Moravy said that the Model 3 Plaid would likely adopt the carbon-sleeved motors that the Model S Plaid had. However, packaging would be a major challenge, as Moravy said on the podcast, it would be a “tight engineering squeeze.”
It’s important to note that there are no active production plans for the Model 3 Plaid at this point, but it’s also worth noting that with the Model S and Model X Plaid no longer available, Tesla would likely be willing to introduce something that is even more white-knuckle than the Model 3 Performance, which already boasts a 2.9-second 0-60 MPH acceleration rate and a top speed of 163 MPH.
Of course, there is the Roadster, but we don’t know when that will exactly make it to market, and we know that, for sure, it will not be accessible to many.
Tesla unveils juicy new detail on the Roadster and hints at new unveil timeline
Tesla has prided itself in building some of the best cars out there, but they’re also interested in building cars that are simply fun to be in.
A Plaid Model 3 could truly push the limits and could end up being one of the best cars Tesla will ever build, especially if it can shave off at least half of a second from its 0-60 MPH time and increase its top speed slightly.
More than anything, the real changes will be in the ride and aerodynamics. Tesla improving things like the suspension, handling, and downforce will be the true trademarks of its Plaid powertrain; putting it in the Model 3 could be a great move for the company and for customers interested in high-end performance.
