Tesla has shared a unique new project at its Gigafactory Berlin-Brandenburg, featuring a small, dedicated facility that’s powered only by solar and the company’s home battery.

On Tuesday, Tesla’s Manufacturing account on X posted about the so-called “Giga small haus,” which is a building and display exhibit at Giga Berlin that’s powered only by the sun and the Powerwall 3. The building is a small room featuring a Tesla Model Y, an informational wall display detailing the Powerwall’s capabilities, and a ton of bright lighting to help make the company’s point.

The wall display features the Tesla Powerwall 3 and a Gateway, along with the following text about the hardware and the exhibit, as translated into English from German:

The Powerwall is a compact power storage unit that stores solar power or grid power. This power can be used to power the devices in your home day and night—even during power outages.

Customizable power management features allow you to use your stored power for backup, to reduce your electricity bill, and more.

Storing Surplus Electricity

If your solar system generates more electricity than you need, you can store the extra power in the Powerwall for later use. The Powerwall can also charge itself from the public power grid when electricity prices are low.

Use electricity cleverly

Your stored power is always available – day, night, or during a power outage. One Powerwall can power your entire home – including heating, air conditioning, and other major appliances.

Save and earn

Powerwall can optimize stored electricity based on your usage history and weather forecasts and dynamic electricity rates to power your home more efficiently during the day and at night.

Solar power for everything

Thanks to the fully integrated solar power inverter, the Powerwall can efficiently store your solar power and convert it into alternating current for your household.

Tesla has used creative tactics for educational and advertising purposes many times in the past, and this comes as the company’s most recent public-facing developments at the Grünheide facility. Earlier this month, the company also highlighted how far Giga Berlin has come in the five years since Elon Musk first announced the project in 2019—including its production milestone of over 400,000 Model Y units, delivery to 37 countries, and its employment of 12,000 employees.

The company has also pointed to its water recycling facility at Giga Berlin in recent months, and its efforts to re-plant three times the number of trees it cuts down for an upcoming expansion project. For employees, the company also built an incoming railway, offering a free, now-electric “Giga Train” for workers in neighboring communities to be able to commute to work.

Last December, just weeks after the launch of the Cybertruck and hints at an upcoming launch of the Powerwall 3, Tesla used the two and a solar roof to deliver, install, and power an art exhibit in San Francisco 24 hours a day.

Elon Musk has been ranked No. 1 on Forbes’ inaugural list of America’s 250 Greatest Innovators. The ranking places Musk at the top of modern American innovation as the publication kicks off a series celebrating the nation’s 250th anniversary.

Forbes described innovation as “the grease in the economic engine” and the force that transforms industries and creates new ones. The publication highlighted that its honorees are not just inventors, but business leaders who successfully bring breakthroughs to market.

Musk, 54, was ranked No. 1 in this year’s list. Forbes noted that he is “the only person in history to have founded (or grown from nearly nothing) five companies, each with multibillion-dollar valuations, each in a different industry.” Those companies include Tesla, SpaceX, Neuralink, xAI, and The Boring Company.

Forbes’ methodology began with nearly 1,000 nominees submitted by its reporters. A panel of judges, including venture capitalist Jim Breyer, journalist Kara Swisher, and strategy expert Rita McGrath, ranked candidates based on creativity, breadth, engagement, disruption, and commercial impact. Artificial intelligence tools, including ChatGPT and Gemini, were also used to assess candidates before editors finalized the rankings.

The publication noted that more than one-third of the list consists of women and people of color, reflecting shifts in innovation and entrepreneurship over time. All individuals listed are also American citizens, though many were born abroad, including Musk himself. Musk was born in Pretoria, South Africa.

Ranked No. 2 is Jeff Bezos, 61, who Forbes credited with upending America’s $7.4 trillion retail industry through Amazon before pioneering cloud computing with Amazon Web Services. The publication highlighted that Bezos now focuses on space exploration through Blue Origin and artificial intelligence manufacturing systems at Prometheus.

At No. 3 is Bill Gates, 70, who helped launch the personal computing revolution and built Microsoft into the dominant force in workplace software. Forbes also highlighted Gates’ reinvention at age 50 as a data-driven philanthropist, including his role in helping eradicate polio from India.

Tesla Model Y tops California vehicle sales despite Elon Musk backlash

Data from the California New Car Dealers Association (CNCDA) showed the Model Y outsold its nearest competitor by more than 50,000 units.

The Tesla Model Y was California’s best-selling new vehicle in 2025 for the fourth straight year, despite protests against CEO Elon Musk and a changeover to the Model Y’s updated variant that caused a pause in production and deliveries early in the year.

Data from the California New Car Dealers Association (CNCDA) showed the Model Y outsold its nearest competitor by more than 50,000 units, according to KRON4.

The Model Y recorded 110,120 registrations in California in 2025. The second-best-selling vehicle, the Toyota RAV4, posted 65,604 units, followed by the Toyota Camry at 62,324. The Tesla Model 3 ranked fourth with 53,989 sales, ahead of the Honda Civic at 53,085 units.

Despite leading the state, Model Y sales have trended downward year-over-year. Registrations fell from 132,636 in 2023 to 128,923 in 2024, and then to 110,120 in 2025. Overall Tesla sales in California also declined, dropping from 238,589 in 2023 to 202,865 in 2024 and 179,656 in 2025.

The slowdown comes as the federal $7,500 EV tax credit ended, removing a key incentive that had supported electric vehicle demand for years.

“Tesla has a few advantages. Tesla, as a brand, has a status, cache, so I think folks in certain parts of the Bay. Owning a Tesla is a thing. I think that’s breaking down over time, especially given the political controversies surrounding Mr. Musk,” CNCDA President Brian Maas said.

California saw multiple anti-Musk protests in 2025, along with notable reports of consumer-owned Teslas being vandalized and attacked by protesters and activists. The fact that the Model Y and Model 3 remained strong performers in California is then a testament to the quality and value of the two vehicles. 

Tesla’s sales of the Model Y and Model 3 might see an increase this year, as the company has announced that it is sunsetting its two more expensive cars, the Model S and Model X. With the Model S and Model X retired, more consumers will likely go for the Model Y and Model 3.

“Maybe the Model S has outlived its usefulness in terms of attracting customers. It’s no surprise the ones they kept are the Model Y and Model 3,” Maas noted.

Tesla Supercharger left offline as Swedish court backs union strike

The completed Supercharger has been stalled for nearly two years amid Tesla’s conflict with the IF Metall union in Sweden.

Tesla’s Supercharger station in Ljungby, Sweden will remain without power after a Swedish administrative court rejected the company’s appeal to force a grid connection to the site. The completed Supercharger has been stalled for nearly two years amid Tesla’s conflict with the IF Metall union in Sweden.

The court ruled that the ongoing union strike against Tesla Sweden is valid grounds for the Supercharger’s connection delay, as noted in an Allt Om Elbil report. 

The Ljungby Supercharger was one of the first charging stations that were denied grid access after IF Metall launched its strike against Tesla Sweden in late 2023. Electricians at local grid operator Ljungby Energinät were pulled into a sympathy strike by the Seko union, preventing the site’s connection.

Tesla reported both Ljungby Energinät and Gävle Energi Elnät AB to the Swedish Energy Market Inspectorate, arguing that grid operators failed to meet their legal obligation to provide connection to the location within a reasonable time frame.

The regulator ruled that the strike represented a valid exception under Swedish law, however, citing constitutional protections for industrial actions.

Tesla responded by appealing to the Administrative Court in Linköping, claiming it had the right to connection within a reasonable period, generally no more than two years. Tesla Sweden also argued that the country’s Electricity Act conflicts with EU law. The court rejected those arguments.

“The Administrative Court today finds that granting the company’s request in practice applies to the same thing as the blockade and that it would mean that the blockade would be ineffective. 

“Such a decision would contradict the principle that labor market conflicts should be resolved to the greatest extent possible by the labor market parties, not by the state. The industrial action is also constitutionally protected,” Chief Councilor Ronny Idstrand stated.

The court also concluded that the Electricity Act does not conflict with EU regulations and that special reasons justified the extended delay.

While the ruling was unanimous, Tesla Sweden may appeal the decision to a higher administrative court.
