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 secures FAA approval for 44 annual Starship launches in Florida
The FAA’s environmental review covers up to 44 launches annually, along with 44 Super Heavy booster landings and 44 upper-stage landings.
SpaceX has received environmental approval from the Federal Aviation Administration (FAA) to conduct up to 44 Starship-Super Heavy launches per year from Kennedy Space Center Launch Complex 39A in Florida.
The decision allows the company to proceed with plans tied to its next-generation launch system and future satellite deployments.
The FAA’s environmental review covers up to 44 launches annually, along with 44 Super Heavy booster landings and 44 upper-stage landings. The approval concludes the agency’s public comment period and outlines required mitigation measures related to noise, emissions, wildlife, and airspace management.
Construction of Starship infrastructure at Launch Complex 39A is nearing completion. The site, previously used for Apollo and space shuttle missions, is transitioning to support Starship operations, as noted in a Florida Today report.
If fully deployed across Kennedy Space Center and nearby Cape Canaveral Space Force Station, Starship activity on the Space Coast could exceed 120 launches annually, excluding tests. Separately, the U.S. Air Force has authorized repurposing Space Launch Complex 37 for potential additional Starship activity, pending further FAA airspace analysis.
The approval supports SpaceX’s long-term strategy, which includes deploying a large constellation of satellites intended to power space-based artificial intelligence data infrastructure. The company has previously indicated that expanded Starship capacity will be central to that effort.
The FAA review identified likely impacts from increased noise, nitrogen oxide emissions, and temporary airspace closures. Commercial flights may experience periodic delays during launch windows. The agency, however, determined these effects would be intermittent and manageable through scheduling, public notification, and worker safety protocols.
Wildlife protections are required under the approval, Florida Today noted. These include lighting controls to protect sea turtles, seasonal monitoring of scrub jays and beach mice, and restrictions on offshore landings to avoid coral reefs and right whale critical habitat. Recovery vessels must also carry trained observers to prevent collisions with protected marine species.

Texas township wants The Boring Company to build it a Loop system
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge.”
The Woodlands Township, Texas, has formally entered The Boring Company’s tunneling sweepstakes.
The township’s board unanimously approved an application to The Boring Company’s “Tunnel Vision Challenge,” which offers up to one mile of tunnel construction at no cost to a selected community.
The Woodlands’ proposal, dubbed “The Current,” features two parallel 12-foot-diameter tunnels beneath the Town Center corridor near The Waterway. Teslas would shuttle passengers between Waterway Square, Cynthia Woods Mitchell Pavilion, Town Green Park and nearby hotels during concerts and large-scale events, as noted in a Chron report.
Township officials framed the tunnel as a solution for the township’s traffic congestion issues. The Pavilion alone hosts more than 60 shows each year and can accommodate crowds of up to 16,500, often straining Lake Robbins Drive and surrounding intersections.
“We know we have traffic impacts and pedestrian movement challenges, especially in the Town Center area,” Chris Nunes, chief operating officer of The Woodlands Township, stated during the meeting.
“The Current” mirrors the Loop system operating beneath the Las Vegas Convention Center, where Tesla vehicles transport passengers through underground tunnels between venues and resorts.
The Boring Company issued its request for proposals (RFP) in mid-January, inviting cities and districts to pitch local uses for its tunneling technology. The Woodlands must submit its application by Feb. 23, though no timeline has been provided for when a winning community will be announced.
Nunes confirmed that the board has authorized a submission for “The Current’s” proposal, though he emphasized that the project is still in its preliminary stages.
“The Woodlands Township Board of Directors has authorized staff to submit an application to The Boring Company, which has issued an RFP for communities interested in leveraging their technology to address community challenges,” he said in a statement.
“The Board believes that an underground tunnel would provide a safe and efficient means to transport people to and from various high-use community amenities in our Town Center.”

Tesla Model Y wins 2026 Drive Car of the Year award in Australia
The Model Y is already Australia’s best-selling EV in 2025 and the tenth best-selling vehicle overall.
The Tesla Model Y has been named 2026 Drive Car of the Year overall winner, taking the top honor after being judged as the vehicle that “moves the game forward the most for Australian new car buyers.”
The Model Y is already Australia’s best-selling EV in 2025 and the tenth best-selling vehicle overall, but the vehicle’s Juniper update strengthened its case with new ownership benefits and expanded software capability.
Drive’s overall award compares category winners and looks at which model most significantly advances the local new car market. In 2026, judges pointed to the Model Y’s five-year warranty and the availability of Full Self-Driving (Supervised) as a monthly subscription as key differentiators.
Priced from AU$58,900 before on-road costs, the all-electric crossover SUV offers a lot of value compared to similarly sized petrol and hybrid rivals. The ability to access Tesla’s Supercharger network across Australia also reduces friction for buyers moving to EV ownership.
Owners can add FSD (Supervised) for AU$149 per month. While it still requires driver oversight, the system expands the vehicle’s advanced driver-assistance capabilities and reflects Tesla’s software-first approach.
“The default choice for a reason. The Tesla Model Y makes the transition to electric both effortless and rewarding,” Drive wrote.
The 2025 Model Y facelift also sharpened the vehicle’s exterior, highlighted by a distinctive rear light bar that gives the crossover SUV a more modern road presence.
Drive described the Model Y as a benchmark for combining practicality, efficiency and technology at an accessible price point. With eligibility for federal Fringe Benefit Tax exemptions through novated leasing, its value proposition has improved for numerous buyers.
For 2026, the Model Y’s combination of range efficiency, charging access and software capability proved decisive. Ultimately, the award all but cements the Model Y’s position as one of the most influential vehicles in Australia’s evolving new-car market today.
