Making solar panels a Tesla work of art could be the change we need
In his Master Plan, Part Deux released last week, Elon Musk made one of his priorities “a smoothly integrated and beautiful solar-roof-with-battery product that just works.” We have heard a lot about solar panel efficiency over the years, but beauty? That hasn’t been a consideration. One solar panel looks very much like another solar panel — until now.
Wired writes in an article dated July 22, “For decades now, going solar has meant sticking what looks like a bunch of computer monitors to your roof.” Hardly the look that many consider ideal for their homes. “Some people will always celebrate the tech-y symbolism of a typical solar panel,” says Aaron Dorf, an architect at architecture and design firm Snøhetta.
Dorf thinks the solar panel “will eventually become a first generation relic, like an Atari or a car phone.” Looking to the near future, he believes things like installation cost and solar cell efficiency will cease to be limiting factors. “Musk is smart to directly target what may be the more significant threshold—beauty.”
We can’t know for certain what Elon intends but excellent design has always been an important component of everything he has done. As Tesla transforms itself into an energy company, we should expect the same level of commitment to beautiful design it is known for.
Others are engaged in designing the solar systems of the future. Sistine Solar makes innovative “Solarskin” panels which match the design of your existing roof. They are scheduled to go on sale next year. T.R. Ludwig, co-founder of Brooklyn Solarworks, says solar panels that can utilize sunlight striking both sides of its panels are more efficient and more attractive. “It’s an interesting aesthetic — more minimal, more sleek,” Ludwig says.
-->Solar panels are a great way of harvesting energy from the great “fusion reactor in the sky,” as Elon likes to call the sun. But not everyone is thrilled at the idea of solar panels on every rooftop. “When you start talking to a fire department about covering your building with solar panels, you get, ‘well, what happens if it burns? And what happens if my guys are underneath this, fighting a fire?” says Brian Lane, managing principal at Koning Eizenberg Architecture.
Energy storage creates other legal challenges. Because batteries are a potential fire risk, it is nearly impossible to get permits for them approved in cities like New York. There is also an issue with durability. The useful life of solar panels today is 20 to 25 years. Most roofs are intended to last 50 years.
Malay Mazumdar, a professor in electro-physics at Boston University, asks “If you integrate the roof with the solar panel…..should you change the entire roof?” If Tesla wants to design solar roofs that are stunning and smoothly integrated, they should also make them durable, or at least easy to replace, Wired says.
Another issue with solar panels is their orientation toward the sun. Not every roof is ideally suited for a solar installation. Some systems feature tracking systems that move the panels during the day to maximize exposure to the sun, but they add complexity and cost to the system.
No doubt Elon Musk has considered all these factors and has answers for each and every one of them. The one thing we can be sure of is that Elon will bring all of his creative powers to bear on the issue of solar power. If his commitment brings the same level of disruption to the electricity industry as it has to the automobile sector, he will further accelerate the changeover from fossil fuels to renewable energy that is at the heart of all his endeavors.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.
