Deeper Tesla, Panasonic ties could lead to a Smart Home future
A growing partnership between Tesla and Panasonic on solar cell production and storage batteries may one day eliminate residential reliance on the power grid and provide the capacity to recharge electric cars each night. However, to secure this collaboration on solar cell and module production, Tesla’s proposed SolarCity acquisition must first be approved by shareholders on November 17, 2016.
In the meantime, Tesla and Panasonic have entered into a non-binding letter of intent under which they will begin collaborating on the manufacturing and production of photovoltaic (PV) cells and modules in Buffalo, New York. The Buffalo facility will become the largest solar panel factory in North America, with expectations to employ 1,460 workers and produce up to 10,000 panels per day.
A blog post on Tesla’s website acknowledged that the continued partnership with Panasonic is an important step in creating fully-integrated energy products for businesses, homeowners, and utilities and furthers Tesla’s mission toward a sustainable energy future.
The Relationship between Tesla and Panasonic
The October 16, 2016 announcement confirmed that this newest collaboration extends the established relationship between Tesla and Panasonic, which includes the production of electric vehicle and grid storage battery cells at Tesla’s Gigafactory outside Sparks, Nevada. The $5 billion Gigafactory will produce batteries for the Model 3 electric car and energy storage products for home and utilities.
“We expect that the collaboration talks will lead to growth of the Tesla and Panasonic relationship,” said Shuuji Okayama, vice president of Panasonic’s Eco Solutions unit.
Battery cell production will begin by late 2016 and is expected to reach full capacity by 2018, producing more lithium ion batteries annually than were produced worldwide in 2013. In cooperation with Panasonic and other strategic partners, the Gigafactory will produce batteries that have the capacity to drive down the per kilowatt hour (kWh) cost of a battery pack by more than 30 percent. That anticipated cost drop is crucial, as current battery costs are untenable.
Panasonic plans to begin PV cell and module production at the Buffalo facility in 2017, and Tesla intends to provide a long-term purchase commitment for those cells from Panasonic. The Tesla/ Panasonic collaboration could mean that energy from solar panels will be pumped into home storage batteries. No longer would residential home solar systems follow the traditional model of selling back to utilities.
Panasonic’s Future Home
The proposed Tesla/ Panasonic collaboration would shift Panasonic’s historic focus from consumer electronics products and onto housing, automotive information systems, and vehicle batteries, which “would be a win” for Panasonic, according to Bloomberg. Panasonic’s transition to the home electric market began in 2009 with its Tokyo Future Home, which features the latest environmental technologies and a few prototypes. The house is designed to aid natural ventilation and cut down on air conditioning. The walls of the house are lined with a thin and efficient insulator that cuts down on heating and cooling costs. LED lights, which use much less power than incandescent bulbs and last longer than current fluorescent models, are sensor-controlled. Extra generated electricity is stored in a prototype accumulator battery of lithium ion cells for later use. The lights, power, heating, and other apps are controlled in a high-tech in-house network with living room TV at the center.
The aim of Panasonic’s energy-saving house is to be carbon neutral in energy usage.
Tesla’s Smart House Could Utilize Panasonic’s Technology
Tesla is currently developing advanced systems that adapt to the needs of the environment with the goal is to bring top quality affordable systems that provide energy efficiency, quality of life, and home security.
Already, smart home system are able to cut electric energy spending by 50%, or in some cases go off-grid using Tesla batteries combined with solar. Lights, air conditioning, and all other appliances are automatically managed, turning on and off, depending on the time of day, temperature, motion sensors, door and window detectors, and electricity rates. Fingerprint scanner and pin lock, video surveillance, night vision camera, motion sensors, SMS alarms, fire and flood sensors are accessed through a phone.
In 2014, Panasonic opened a smart city near Tokyo that is designed to drastically cut CO2 emissions by 70%, reaching to 1990 levels. It will attempt to reduce water usage by 30 percent and achieve 30 percent renewable energy usage. Called the Fujisawa Sustainable Smart Town (SST), the subdivision southwest of Tokyo focuses on solar power and other environmentally friendly technologies.
Together, Tesla and Panasonic may be able to ground ambitious plans for solar-powered systems that charge smart homes and electric cars and make decentralized renewable energy systems that power homes and car a practical reality. “We are excited to expand our partnership with Panasonic as we move towards a combined Tesla and SolarCity,” JB Straubel, Tesla’s chief technical officer and co-founder, said in a statement. “By working together on solar, we will be able to accelerate production of high-efficiency, extremely reliable solar cells and modules at the best cost.”
The Role of the Projected SolarCity Acquisition
The Tesla/ Panasonic collaboration moving forward is contingent on Tesla’s acquisition of SolarCity, but shareholders must approve the move. Tesla’s bid to acquire SolarCity has been fraught with corporate governance issues because the boards of both companies are deeply intertwined.
Tesla co-founder Elon Musk’s effort to unite Tesla and SolarCity has been under close scrutiny, given six of the seven directors on Tesla’s board have SolarCity ties and SolarCity’s CEO, Lyndon Rive, is Musk’s first cousin.
SolarCity, among the top installers of residential rooftop solar panels in the U.S., acquired solar manufacturer Silevo in 2014. The transaction gave SolarCity the factory in Buffalo where Panasonic will begin photovoltaic cell and module production. If the SolarCity acquisition is successful, Tesla will use the cells and modules in a solar energy system that will work seamlessly with Powerwall and Powerpack, Tesla’s energy storage products. With the aid of installation, sales, and financing capabilities from SolarCity, Tesla will bring an integrated sustainable energy solution to residential, commercial, and grid-scale customers.

New drone video shows Tesla’s Optimus Factory reaching a turning point
New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.
Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.
The Giga Texas Optimus Factory latest update … construction keeps moving fast!
Steel assembly is now only about 5 column grids from the north perimeter beam. Concrete is going in on the three upper floors, rebar is still being laid for more pours, and footing / grade-beam work… pic.twitter.com/qvFPvwnYzW

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.
Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.
Tesla Giga Texas to feature massive Optimus V4 production line
The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.
Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.

Tesla and SpaceX take “Terafab” Trademark fight to Federal Court
Tesla and SpaceX sue a small Illinois firm after cease and desist letters over Terafab.
Tesla and SpaceX are asking a federal judge to rule that their planned Terafab chip factory does not infringe a small Illinois company’s trademark, a request that arrives only after months of quiet negotiation broke down this summer.
The dispute traces to May 18, when Tesla filed three U.S. trademark applications for “Terafab” and “Tesla Terafab,” covering semiconductor chips and related chip making services. TERA-print LLC, a nanotechnology company that has held a federal trademark for “Tera-Fab” since 2021, responded five days later with a cease and desist letter. According to the lawsuit, first reported by Reuters, TERA-print argued that Tesla and SpaceX’s use of “Terafab” would confuse consumers familiar with its own trademark, which covers a desktop photolithography printer sold to researchers for sensor and bioengineering work.
What stands out in the filing is the timing of TERA-print’s own paperwork. One day before sending that cease and desist letter, on May 22, TERA-print applied to expand its existing registration to cover semiconductor materials, silicon chips, nanoelectronic devices and AI design services, categories it had not previously claimed. Tesla and SpaceX call that filing opportunistic in their complaint, noting it arrived two months after Tesla’s public Terafab announcement and just days after Tesla’s own trademark applications went in.
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
By June 10, TERA-print was threatening to sue for federal trademark infringement, false designation of origin and unfair competition, the complaint states. Rather than wait to be sued, Tesla, SpaceX and SpaceXAI met with TERA-print six separate times between June and August trying to resolve the dispute directly. Those talks collapsed, and the companies filed for declaratory judgment this week in the U.S. District Court for the Western District of Texas, asking a judge to find that “Terafab” does not infringe TERA-print’s mark before TERA-print can file a claim of its own.
TERA-print isn’t backing down. The company told PCMag it discussed a settlement with Tesla as recently as September 2 and feels misled by what it called Tesla’s professed interest in settling. Its CTO, Andrey Ivankin, said TERA-print holds a Defense Department contract to fabricate semiconductors and partially owns Mattiq Inc., an AI company built on TERA-print’s products, and that the company will vigorously defend its rights.
Tesla and SpaceX argue the overlap is superficial. Terafab is planned as a $16.8 billion complex spanning roughly 100 million square feet at the Grimes County site SpaceX confirmed last month, built to produce chips for Optimus robots, Tesla’s AI computing needs and SpaceX’s orbital data center ambitions, a scale and purpose the companies say no reasonable consumer would confuse with a tabletop lab printer. TERA-print’s product line has stayed focused on lithography tools for biological and sensor research since it registered its mark in 2021.
The trademark fight is the second legal dispute tied to the Terafab project in the past week, following a separate SpaceX suit aimed at keeping company records about the facility out of public view, as KBTX reported. Whether construction proceeds under the Terafab name now depends on a federal judge in Austin.

Tesla uber bull Ron Baron says ‘the time to buy the stock is now’
In a new interview on Wednesday, Tesla uber bull Ron Baron said that anyone looking to buy the company’s stock should do so as soon as they can.
Baron, founder and CEO of Baron Capital and one of Tesla’s most persistent institutional bulls, used a CNBC Squawk Box appearance on Wednesday to deliver a familiar message with fresh urgency: In his opinion, Tesla stock is a buy:
“The time to buy the stock is now. FSD is catching on, and it’s going to be bigger and bigger. 55% of new buyers are buying it (Teslas) with FSD. It’s going to be everywhere. It’s safer.”
The Baron Capital frontman’s case is built around Full Self-Driving. Tesla reported 1.48 million active FSD subscriptions in the second quarter, up 56 percent year over year, and company officials have said roughly 55 percent of new North American deliveries left with a subscription enabled.
Baron framed that attach rate as proof the product is moving from enthusiast extra to default expectation, and as a reason software, not just vehicle volume, should drive the next phase of value.
His conviction on Tesla shares is not theoretical, as Baron Capital made its first Tesla investment in 2014, after years of meetings that began around the 2010 IPO roadshow. The firm later built a large SpaceX position starting in 2017.

Baron said those Musk-led bets have generated about $30 billion of the $71 billion in profits Baron Capital has produced for clients. He put the firm’s current exposure at roughly $25 billion in SpaceX and $5 billion in Tesla. Personally, he described SpaceX as his largest holding, at about $5 billion, with about $1.5 billion in Tesla and additional Tesla exposure through the firm’s funds.
That concentration is also a statement of loyalty. Asked about talk of a SpaceX-Tesla combination, Baron said he had already walked Elon Musk through arguments for and against a deal, then declined to repeat them on air. His public position was simpler: “Whatever you decide is better is what I’m going to support,” he said to Musk.
Baron also said that he picked up the farewell edition of the Model S after Tesla decided to sunset the vehicle earlier this year, calling it his favorite car he’s ever driven.
