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.

Tesla has launched a new color at Gigafactory Berlin in Germany, home of the company’s “world-class paint shop,” as Elon Musk once called it.
Bringing a new color to Tesla’s Model Y, there are now five available colors for those who will receive a vehicle from Gigafactory Berlin, with four of them being colors offered in other markets.
However, there is now one distinct color that is only available in Germany: Marine Blue.

Priced at €1,300, Marine Blue will cost the same as both Diamond Black and Stealth Grey, while Quicksilver and Ultra Red are available for double the price.
It is the third shade of blue Tesla offers across its lineup, as Deep Metallic Blue and Glacier Blue are also offered, but in other markets.
Tesla has routinely flexed Giga Berlin for having the most advanced paint shop throughout its factories, and it has produced some interesting colors over the past few years, some of which were truly awesome.
Tesla Giga Berlin is getting a world-class paint shop, new color ‘layers’ to come
In 2020, Musk said, “Giga Berlin will have the world’s most advanced paint shop, with more layers of stunning colors that subtly change with curvature.”
He also detailed the company’s plans to upgrade the Fremont and Shanghai paint shops. Gigafactory Texas was not yet unveiled. Tesla has worked to improve those facilities, especially in Fremont.
It was able to roll out the new Diamond Black color earlier this year.
However, Giga Berlin seems to remain the standard in terms of paint for Tesla. It routinely offers new colors.
For example, back in 2022, Tesla rolled out its familiar Quicksilver color for the Model Y, while also introducing Midnight Cherry Red, a color close to burgundy. However, the company chose to discontinue the color after determining internally that customers no longer wanted to buy it.
Midnight Cherry Red was removed as an option earlier this year, likely to make way for the development of the new Marine Blue.

Tesla Autopilot visualization gets big upgrade with tons of new additions
The AP visualization shows up on the center touchscreen and illustrates the surroundings of the cars. It has gotten better in recent years, as it is able to outline types of vehicles, pedestrians, animals, and more.
Tesla’s Autopilot visualization just got a big upgrade as the company added tons of new additions to what it will be able to render in terms of a vehicle’s surroundings.
The AP visualization shows up on the center touchscreen and illustrates the surroundings of the cars. It has gotten better in recent years, as it is able to outline types of vehicles, pedestrians, animals, and more.
Tesla just fixed a four-year-old bug with Full Self-Driving visualization
However, it still does not have every single application, and acquiring them will take some time. If an object or vehicle is visible to the vehicle but an accurate render is not available, the car will instead pick whatever is closest.
For example, I passed an Amish family yesterday in Lancaster, PA, and instead of illustrating the horse and carriage, it simply showed a small box truck.
In an effort to make the Autopilot and Full Self-Driving suites more robust and accurate, Tesla has added a substantial amount of vehicle renders, which will become available in the coming weeks.
The visualizations were found by Tesla hacker @greentheonly, who posted them on X.
The new visualization renders are:
- Ambulance
- Firetruck
- Garbage Truck
- Schoolbus
- European Semi Truck
- Golf Cart
- Person on a Scooter
- Person on a Skateboard
- Stroller
- Street Sweeper
- Three-Wheeler
- Trailer
- Train
- Tram
- Person in a Wheelchair
Here is an image with all of the Autopilot visualization renders:

The visualization is a crucial part of manual operation and can be considered a distinct advantage that Tesla has over other companies.
It continues to be an effort that Tesla invests heavily in, as it keeps refining the suite and making it more robust with additional visualizations and animations.
Recently, it was revealed that Tesla is planning to utilize Unreal Engine for driver visualization to create a realistic depiction of the vehicle’s environment. Tesla has not yet confirmed this, but coding found with the Model S and Model X showed it could be coming in the near future.
Tesla dominated the sales figures for electric vehicles in the third quarter in the United States, but there was one disappointment: the Cybertruck.
As a whole, the EV industry benefitted from the loss of the $7,500 EV tax credit in Q3, which was something many expected. As the credit expired, consumers rushed to showrooms to take the credit and remove $7,500 from the purchase price of their new vehicle.
Will Tesla thrive without the EV tax credit? Five reasons why they might
It was a very interesting time for many companies as they scrambled to figure out how to push as many vehicles out the door as they could in preparation for the tax credit’s removal. In typical fashion, Tesla was able to top every manufacturer and secure a dominating portion of the overall market in Q3.
However, some other OEMs pulled out some surprises, including Chevrolet, Honda, and Ford, which managed to get two vehicles in the top 10, as many as Tesla.
Cox Automotive compiled the data in its Q3 Electric Vehicle Sales Report:
- Tesla Model Y – 114,897
- Tesla Model 3 – 53,857
- Chevrolet Equinox EV – 25,085
- Hyundai Ioniq 5 – 21,999
- Honda Prologue – 20,236
- Ford Mustang Mach-E – 20,177
- Volkswagen ID.4 – 12,470
- Audi Q6 e-tron – 10,299
- Ford F-150 Lightning – 10,005
- Rivian R1S – 8,184
10.5 percent of the automotive sales in the U.S. in Q3 were electric, a new record that surpasses that of Q3 2024, where the total share of sales for EVs was 8.6 percent.
Now, the disappointment that is evident from this list is the fact that there is no Tesla Cybertruck listed. That’s because it was the second-best-selling EV pickup on the market. The company sold 5,385 Cybertruck units in Q3.
The Cybertruck has been a vehicle that has confused many Tesla fans and owners, especially considering the company had such stratospheric expectations for the vehicle while it was in development. Reservation trackers had the truck sitting between one million and two million orders, but it has not lived up to that.
Pricing is the main issue with Cybertruck. Tesla introduced the pickup with Single, Dual, and Tri-motor configurations, priced at $39,990, $49,990, and $69,990. Those price points are simply a thing of the past.
🚨 Tesla Cybertruck was the second-best-selling EV pickup in Q3, Cox Automotive data shows.
It was only outsold by the Ford F-150 Lightning, which sold 10,005 units for the quarter.
