Which style of Tesla’s Solar Roof tile is right for you?
With the explicit goal of making solar panels as appealing as electric cars have become, Tesla CEO Elon Musk has unveiled the company’s newest product: solar roof tiles manufactured with durable, long lasting tempered-glass. The slogan, “Power from above, beauty from the street” captured the product and theme of the unveiling, which took place at Universal Studios in Los Angeles with the sun ready to set in the background.
The new roofs will be a collaboration between SolarCity and Tesla and can be combined with Tesla’s Powerwall 2 home battery. The tiles are hydrographically printed. Musk explained that this process that makes each one a “special snowflake.”
Throughout the product unveiling, Musk emphasized that these solar tiles, which will be integrated into the roof and invisible when viewed from the street, offer a much more attractive option as compared with currently-used solar technology. The tiles will be soon available to the public in four distinct styles. Each is architecturally significant to a home’s core design. Four distinct tile styles reinforce the importance of connecting an architectural past to the Tesla vision of a sustainable future. The “beautiful, affordable, and seamlessly integrated” glass tiles have significant historic origins and contemporary appeal.
Tuscan Glass Tile
This roof, sometimes called Italian Renaissance style, is an element of a home integrated with its setting. Consistent with Musk’s vision of sustainable solutions to a “mine-and-burn” hydrocarbon economy, landscape architecture and gardens balance Tuscan house design. The roof structure is a combination of side gable, cross gable, combined hip and gable, or hipped configuration, often with projecting wings and deep roof overhangs and eaves. The style borrows details from the entire history of Spanish architecture, with architectural elements of paired French doors, classic arches, and some use of wrought iron.
Slate Glass Tile
The most desirable roofing material for more than 1,000 years, slate has been acclaimed for its elegance and unique character. It required a craft person’s expertise and skill in hand shaping and laying it on the roof. The Tesla version likely will resemble thin tiles split into uniform thicknesses. Slate’s aesthetic appearance is due to a wide variety of rich colors and textures that are combined in nearly endless combinations. Found on virtually every class of structure, slate roofs are perhaps most often associated with institutional, ecclesiastical, and government buildings, yet slate was often used on farm and agricultural buildings as well.

Textured Glass Tile
Textured roofing tiles were used in Neolithic China as early as 10.000 B.C. and 5000 years ago in Babylon. By the end of the nineteenth century, as the use of glazed roofing tiles grew, textured tiles became among the most ornamental and distinctive roofing materials. Now featured on many historic buildings, their aesthetic qualities include many shapes, colors, patterns, and textures. Architecturally, a field of textured tiles often covers the majority of a roof’s flat surface, with decorative tiles used along the peak of the roof. In more ornamental installations, the field of tiles may have areas of patterning created by tiles of different shapes, dimensions, or color variations ranging from deep browns to pale pinks to buff or beige. Their interesting appearance has often made textured tile roofs prominent stylistic features of historic structures.

Smooth Glass Tile
Flat smooth tile offers clean lines that compliment a contemporary design with unassuming, no-frills elegance. It contains a straightforward, stripped-down geometry and a means of securing an organic bond between old, existing architecture and new buildings. This is particularly important in optically sensitive areas where contemporary architecture accentuates an important visual impression. All parts of the resultant ensemble stem from a single smooth tile source, which appears as if it grew up over the centuries. Smooth glass tiles can contribute to an eclectic conglomeration of heritage-listed façades and modern stylistic elements. Optically robust, these tiles now provide an interplay of nuances that was once typical of hand-crafted products.
Tying Architecture and Aesthetics to Energy Power Solutions
The Tesla solar roof tiles offer high efficiency solar power which will produce energy even during high temperature days. Color louver film allows cells to blend into the roof while exposing them to the sun above. With tempered glass, the material is extremely impact resistant. The solar integrates with Tesla home batteries to collect energy during the day for use in the evening once the sun goes down. Musk tweeted that “solar glass tiles can also incorporate heating elements, like rear defroster on a car, to clear roof of snow and keep generating energy.”
Tesla expects to start installing the solar roofs next summer. More durable than normal roofing tiles, the solar roofs can be tied to the updated Powerwall 2 home battery (14 kWh, $5500) which the company also showcased at the unveiling event.
The announcement of this solar innovation implies that the Tesla/ SolarCity merger will receive upcoming shareholder votes and approval.

Tesla’s golden era is no longer a tagline
Tesla “golden era” teaser video highlights the future of transportation and why car ownership itself may be the next thing to change.
The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.
Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.
Tesla Cybercab production ignites with 60 units spotted at Giga Texas
The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.
Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.
During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.

Tesla’s last chance version of the flagship Model X is officially gone
The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Tesla enabled a last-chance version of its two flagship vehicles, the Model S and Model X, over the past few weeks. The Model X, the company’s original SUV, is officially gone.
Tesla has officially closed the book on its most exclusive send-off for the Model X. The limited-run Model X Signature Edition—priced at $159,420 before fees and limited to just 100 units—is now sold out, with reservations closed as of April 16.

The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Every unit featured an exclusive Garnet Red exterior paint, unique badging, and a standard six-seat configuration. With full Plaid powertrain specs—Tri-Motor All-Wheel Drive, over 1,000 horsepower, and blistering acceleration—it was positioned as a collector’s item for loyalists who wanted one last shot at owning a piece of Tesla history.
The timing is no coincidence.
Tesla announced earlier this year that it would discontinue regular production of both the Model S and Model X to repurpose the Fremont factory’s dedicated lines for mass production of its Optimus humanoid robots.
Elon Musk has repeatedly emphasized that Optimus could ultimately become more valuable to the company than its vehicle business, with ambitions to build hundreds of thousands of units annually.
The Signature Editions served as a final “runout” series: 250 for the Model S and only 100 for the Model X, all built to the highest Plaid specification before the line is converted.
Deliveries of the remaining Signature units are scheduled to begin in May 2026. For buyers who secured one, it’s the ultimate swan song for a vehicle that helped define Tesla’s early luxury EV dominance.
Launched in 2015, the Model X introduced falcon-wing doors, a panoramic windshield, and class-leading performance that turned heads and set benchmarks. While newer models like the Cybertruck and refreshed Model Y have taken center stage, the Model X Plaid remained a halo product for those seeking maximum range, space, and speed in an SUV package.
With inventory of standard Model X units already nearly exhausted across the U.S., the rapid sell-out of the Signature Edition underscores enduring demand for Tesla’s premium flagships even as the company pivots toward robotics and autonomy.
For enthusiasts, these 100 garnet-red SUVs will likely become instant collector’s items—tangible reminders of the vehicles that built the brand before Tesla’s next chapter fully begins. The last chance is gone, but the legacy endures.

Tesla Optimus V3 hand and arm details revealed in new patents
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
Tesla is planning to soon reveal its latest and greatest version of the Optimus humanoid robot, and a series of new patents for the hands and arms, with the former being, admittedly, one of the most challenging parts of developing the project.
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
The designs relocate heavy actuators to the forearm, route cables through a sophisticated wrist design, and employ innovative joint assemblies to achieve human-like dexterity while enabling lightweight construction and high-volume manufacturing.
Core Tendon-Driven Hand Architecture
The primary patent, which is titled “Mechanically Actuated Robotic Hand,” details a cable/tendon-driven system.
Actuators are positioned in the forearm rather than the hand. Each finger features four degrees of freedom (DoF), while the wrist adds two more.
Tesla’s Optimus V3 robot hand looks to have been revealed in a new international patent published today.
The patent describes a tendon/cable-driven hand:
• Actuators in the forearm
• Each finger has 4 degrees of freedom
• The wrist has 2 degrees of freedom
• Tendon-driven… pic.twitter.com/eE8xLEYSrx— Sawyer Merritt (@SawyerMerritt) April 16, 2026
Three thin, flexible control cables (tendons) per finger extend from the forearm actuators, pass through the wrist, and connect to the finger segments. Integrated channels within the finger phalanges guide these cables selectively—routing behind some joints and forward of others—to enable independent bending without unintended motion.
Patent diagrams illustrate thick cable bundles emerging from the wrist into the palm and fingers, with labeled pivots and routing guides. This setup closely mirrors human forearm-muscle and tendon anatomy, where most hand control originates proximally.
Advanced Wrist Routing Innovation
One of the standout features is the wrist’s cable transition mechanism. Cables shift from a lateral stack on the forearm side to a vertical stack on the hand side through a specialized transition zone.
Boom! @Tesla_Optimus 의 3세대 구조로 추정되는, 로봇 팔 및 관절에 대한 특허가 공개되었습니다.
아티클 작업에 들어가겠습니다.
1년 넘게 기다려 온, 정말 귀한 특허인데, 조회수 100만대로 터져줬으면 좋겠네요. 😉@herbertong @SawyerMerritt@GoingBallistic5 @TheHumanoidHub pic.twitter.com/CCEiIlMFSX

This geometry significantly reduces cable stretch, torque, friction, and crosstalk during combined yaw and pitch wrist movements — common failure points in simpler tendon systems that cause imprecise or jerky motion.
By minimizing these issues, the design supports smoother, more reliable multi-axis wrist operation, essential for complex real-world tasks.
Companion Patents on Appendage and Joint Design
Two supporting patents provide additional depth. “Robotic Appendage” covers the overall forearm-to-palm-to-finger assembly, with a palm body movably coupled to the forearm and finger phalanges linked by tensile cables returning to forearm actuators. Tensioning these cables repositions the phalanges precisely.
“Joint Assembly for Robotic Appendage” describes curved contact surfaces on mating structures paired with a composite flexible member. This allows smooth pivoting while maintaining consistent tension, enhancing durability, and simplifying assembly for mass production.
Executive Insights on Hand Development Challenges
Tesla executives have consistently described the hand as the most difficult component of Optimus.
Elon Musk has called it “the majority of the engineering difficulty of the entire robot,” emphasizing that human hands possess roughly 27–28 DoF with an intricate tendon network powered largely by forearm muscles. He has likened the challenge to something “harder than Cybertruck or Model X… somewhere between Model X and Starship.”
In mid-2025, Musk acknowledged that Tesla was “struggling” to finalize the hand and forearm design. By early 2026, he stated that the company had overcome the “hardest” problems, including human-level manual dexterity, real-world AI integration, and volume production scalability.
He estimated the electromechanical hand represents about 60 percent of the overall Optimus challenge, compounded by the lack of an existing supply chain for such precision components.
These patents directly tackle the acknowledged pain points: relocating actuators reduces hand mass and inertia for better speed and efficiency; advanced wrist routing and joint geometry address friction and crosstalk; and simplified, stackable parts visible in the diagrams indicate readiness for high-volume manufacturing.
Implications for Optimus Production and Leadership
Collectively, the patents portray the Optimus v3 hand not as a mere prototype, but as a production-oriented system engineered from first principles.
The 22-DoF architecture, forearm-driven tendons, and crosstalk-minimizing wrist deliver a clear competitive edge in dexterity. They align with Musk’s view that high-volume manufacturing is one of the three critical elements missing from most other humanoid projects.
For Optimus to become the most capable humanoid robot, its hand needed to replicate the useful and applicable design of the human counterpart.
These filings demonstrate that Tesla has transformed years of engineering challenges into patented, elegant solutions — positioning the company strongly in the race toward general-purpose robotics.
