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.

Elon Musk confirms Tesla Semi will enter high-volume production this year
Musk shared his update in a post on social media platform X.
Elon Musk has confirmed that Tesla will begin high-volume production of the Class 8 all-electric Semi this year.
He shared his update in a post on social media platform X.
Musk confirms Tesla Semi production ramp
Tesla CEO Elon Musk reaffirmed on X that the Semi is finally moving into volume production, posting on Sunday that “Tesla Semi starts high volume production this year.”
The update comes as Tesla refreshed its Semi lineup on its official website, an apparent hint that the program is transitioning from limited pilots into wider commercial deployment. As per Tesla’s official website, two variants of the Semi will be offered to consumers: Standard and Long Range.
The Standard trim offers up to 325 miles of range with an energy consumption rating of 1.7 kWh per mile and a gross combination weight rating of 82,000 pounds. The Long Range version pushes driving range to 500 miles, with Tesla noting a higher curb weight of about 23,000 pounds, likely due to a larger battery pack.
Both trims support fast charging, with Tesla stating that the Semi can recover up to 60% of its range in 30 minutes using compatible charging infrastructure.
Broader Tesla Semi rollout
Tesla has already delivered production Semi units to select partners, including snack and beverage giant PepsiCo as well as logistics behemoth DHL, which confirmed that its truck operates daily in California, traveling roughly 100 miles per day and requiring charging just about once a week.
The company has also partnered with Uber Freight, as noted in a Benzinga report, with Tesla executives previously describing the agreement as a way for fleet operators to experience the Semi’s lower operating and maintenance costs firsthand.
With Musk now publicly committing to high-volume production, the Semi appears poised to move beyond pilot programs and into scaled commercial use, an important step in Tesla’s wider push to electrify heavy-duty and long-range trucking.

Tesla tops France reliability rankings, beating Toyota for the first time
The milestone was celebrated by CEO Elon Musk on social media platform X.
Tesla has overtaken Toyota to become France’s most reliable car brand in 2025, as per a new nationwide reliability ranking published by Auto Plus magazine.
The milestone was celebrated by CEO Elon Musk on social media platform X.
Tesla tops reliability ranking in France
Tesla ranked first overall in Auto Plus’ 2025 reliability study, surpassing long-time benchmark Toyota across all powertrain types, including gasoline, hybrid, and electric vehicles.
The ranking, published on February 6, 2026, evaluated early problems reported in 2025 on vehicles registered in France since January 1, 2018, with fewer than 150,000 kilometers on the odometer, as noted by a Numerama report. This marked Tesla’s first appearance in the magazine’s reliability rankings, which was enabled by the company’s growing vehicle population in the French market.
According to the publication, Tesla vehicles showed no recurring major defects beyond isolated suspension arm issues, which are covered under the company’s four-year or 80,000-kilometer warranty. Other reported issues were described as minor, including occasional screen glitches and door handle concerns.
Why this ranking differs from earlier criticism
Tesla’s top placement contrasts sharply with past assessments from the German Automobile Club (ADAC), which previously ranked the Model 3 and Model Y low in its technical inspection reports. Auto Plus noted that those inspections were focused heavily on factors such as brake disc wear, which are not necessarily the best benchmarks for overall vehicle reliability.
By focusing instead on real-world reliability data and early ownership issues, Auto Plus’ methodology offered a broader picture of how vehicles perform over time rather than how individual components age under inspection standards. The publication emphasized that electric vehicles, with far fewer moving parts than combustion-engine cars, are not inherently less reliable.
While the ranking supports the case that electric vehicles can match or exceed the reliability of traditional brands, the magazine acknowledged limitations in its analysis. Still, Tesla’s debut at the top of the list underscores how perceptions of EV durability are shifting as more long-term data becomes available in major automotive markets like France.

Tesla’s Sweden standoff draws UAW support as unions widen pressure campaign
In a post shared on social media, the United Auto Workers stated that it stands with IF Metall workers who are striking against Tesla Sweden.
The United Auto Workers (UAW) has publicly expressed solidarity with Swedish union IF Metall as its strike against Tesla continues, adding international attention to the extended labor dispute in the European country.
UAW supports IF Metall’s strike
In a post shared on social media, the United Auto Workers stated that it stands with IF Metall workers who are striking against Tesla Sweden. UAW Region 8 Director Tim Smith stated that the union fully supports IF Metall’s efforts to secure a collective bargaining agreement with the automaker.
“UAW stands with IF Metall workers on strike against Tesla, fighting for a collective bargaining agreement. UAW Region 8 Director Tim Smith pledged the UAW’s full support and solidarity,” the UAW International Union stated in its post.
IF Metall launched its strike against Tesla Sweden in late 2023 over the electric car maker’s refusal to sign a collective agreement. The action has since been supported by other unions through sympathy strikes affecting ports, logistics, and service operations.
Tesla Sweden has maintained that it complies with Swedish labor laws and offers competitive pay and benefits, though the company has not publicly commented on the UAW’s latest show of support.
Tesla owners get union attention
Pro-union groups in Sweden have recently expanded their outreach beyond Tesla’s facilities and workforce. Activists have begun distributing informational leaflets against the EV maker directly on Tesla vehicles parked across Stockholm, as per a report from Swedish outlet Dagens Arbete.
The yellow slips, designed to resemble parking notices, urge regular Tesla owners to pressure the company into signing a collective agreement. Organizers involved in the effort have argued that the leaflets are intended to simply inform consumers rather than single out individual owners. When owners are present, however, activists stated that they explain the dispute verbally.
Tesla has not issued a public response regarding the leaflet distribution campaign as of writing.
