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.

California snubs Tesla in its newly passed EV incentive that favors Rivian and Lucid
California passed a $135 million EV incentive that rewards Rivian and Lucid while sidelining Tesla
California just drew a line in the EV incentive sand to put Tesla on the wrong side of it. The state recently passed a $135 million program offering first-time electric vehicle buyers a direct incentive with no application required, but the rules were written in a way that leaves Tesla at a structural disadvantage compared to Rivian and Lucid.
The program caps eligible vehicles at $50,000 for new EVs and $25,000 for used ones. That pricing threshold rules out a significant portion of Tesla’s lineup, though some lower-priced Model 3 and Model Y configurations would still qualify. California-based automakers are exempt from the price cap entirely, regardless of what their vehicles cost. Rivian, headquartered in Irvine, and Lucid, based in the San Francisco Bay Area, both benefit from that exemption. Rivian’s R2 starts at roughly $45,000 but has versions above the cap. Lucid’s Air and Gravity start at $70,990 and $79,990 respectively, well above any threshold a non-California company would face.
California hits Tesla Cybercab and Robotaxi driverless cars with new law
Tesla built its reputation and a significant portion of its early market share in California, where EV adoption has consistently led the nation. The company operates its original factory in Fremont, California, and the state was home to Tesla’s headquarters for most of its existence. That changed in 2021 when Tesla moved its corporate headquarters to Austin, Texas. Since then, the relationship between the company and California Governor Gavin Newsom has been openly adversarial, with Musk and Newsom trading public criticism on multiple occasions.
California’s EV incentive landscape has shifted repeatedly in recent years, and Tesla has previously lost eligibility for state-level programs as its vehicles exceeded income-adjusted price thresholds. The federal $7,500 EV tax credit, which Tesla models have qualified for and lost depending on policy cycles, is no longer available after it expired without renewal, making state-level programs more meaningful to buyers than they have been in years.
The practical impact for buyers is more nuanced than the headline suggests. California residents purchasing a Tesla under $50,000 for the first time can still access the incentive. But the exemption written for California-based manufacturers is a structural advantage that rewards where a company plants its headquarters flag rather than where it builds its products, and Tesla moved that flag to Texas.

SpaceX’s newest logo confirms everything about what it’s become
SpaceX officially absorbed xAI under the SpaceXAI brand, completing the largest private merger in history.
SpaceX made its corporate transformation official in May 2026 when Elon Musk posted on X that xAI would cease to exist as a standalone company. “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX,” he wrote.
A new SpaceXAI logo was announced today, visually embedding the xAI letters inside the SpaceX identity, which can be seen as a deliberate design choice that signals the merger is not a partnership but a full absorption and XAi a core function of the same company. The same way Starlink is not a separate brand but a SpaceX product. The announcement closed the loop on a process that began February 2, 2026, when SpaceX acquired xAI in the largest private merger in history, valued at $1.25 trillion. SpaceX at $1 trillion and xAI at $250 billion.

The reason SpaceX bought xAI was stated plainly by Musk at the time of the deal: to build orbital data centers. SpaceX had simultaneously filed with the FCC to launch up to one million satellites designed to function as AI compute nodes in low Earth orbit, escaping what Musk described as the energy constraints limiting AI development on Earth.
xAI provided the AI software stack, with Grok, the X platform, and the Colossus supercomputer infrastructure in Memphis with over 220,000 NVIDIA GPUs, while SpaceX provided the rockets, Starlink, and the capital base to fund it. The two companies needed each other. xAI was burning $2.5 billion in losses on $250 million in revenue. SpaceX was generating an estimated $8 billion in profit on $15 billion in revenue and needed an AI narrative to command the valuation it was targeting for its IPO.
What SpaceX has done, regardless of how the orbital AI vision ultimately plays out, is walk into a public market as something no company has been before: a rocket manufacturer, satellite internet provider, AI software company, social media platform, and supercomputer operator under one ticker. Whether that combination is worth $2 trillion depends entirely on which of those businesses you believe in most.

Tesla challenges startups to score a gig inside its most advanced European factory
Tesla is challenging startups to bring their best battery tech directly to Gigafactory Berlin.
Tesla has issued an open challenge to startups across Europe, inviting them to bring their best battery technology directly to the floor of Gigafactory Berlin. The program, called the JUNI x Tesla Battery Cell Giga Challenge, opened applications this month with a deadline of July 24, 2026, and is targeting startups with solutions that can make battery cell manufacturing faster, cheaper, safer, and more scalable at an industrial level.
The timing of the challenge is directly tied to Tesla’s most aggressive European battery investment yet. On May 12, 2026, Giga Berlin plant manager André Thierig announced a $250 million investment to scale the factory’s annual 4680 cell production capacity from 8 GWh to 18 GWh, more than doubling the previous target set just months earlier in December 2025. Thierig confirmed the expansion on X, saying the investment “will enable 18 GWh of annual 4680 cell production and create more than 1,500 new jobs.” Combined with a previously announced battery investment at the Grunheide site now approaches $1.2 billion.
Today, we announced a $ 250m investment for our Giga Berlin Cell factory. This will enable 18GWh of annual 4680 cell production and create more than 1500 new jobs. Good news during challenging times for the German industry. pic.twitter.com/ou4SWMfWh9

The challenge is looking specifically for startups with proven solutions across five categories: materials, equipment, operations, automation, and artificial intelligence. Applications are screened directly by Tesla’s cell manufacturing team in Grunheide, and the strongest submissions move through technical discussions, a pitch day in front of Tesla stakeholders, and potentially a paid pilot project with the cell team. Tesla is not looking for ideas at concept stage. The program requires applicants to demonstrate working prototypes, test data, or prior pilots before being considered.
The historical context matters here. Elon Musk first announced plans for what he called the world’s largest battery cell production facility alongside the Giga Berlin car factory back in 2020, targeting up to 250 GWh of annual capacity. Those plans were shelved in 2022 when Tesla shifted its battery investment focus to the United States to take advantage of Inflation Reduction Act incentives. The revival of cell production at Giga Berlin, now backed by over $1 billion in committed capital, represents a return to an ambition that was set aside for three years. As Teslarati has reported, the 4680 format is central to Tesla’s long-term cost reduction strategy across vehicles, energy storage, including the Tesla Semi and Cybercab.
By opening the challenge to outside startups, Tesla is acknowledging that reaching 18 GWh at Grunheide will require technology it does not currently have in-house, and it is willing to pay for the right solutions. For a startup in the battery supply chain, a paid pilot with Tesla’s European cell team is as close to a direct commercial path as the industry offers.
