Tesla patent hints at stunning colored Solar Roof tiles with zero compromises
Elon Musk recently noted on Twitter that Tesla would be prioritizing the production of its Solar Roof tiles this coming 2019. These updates were announced not long after the company invited local media from Buffalo, NY to tour Gigafactory 2, the company’s facility which is producing the unique solar shingles. As Tesla continues to prepare for the ramp of the Solar Roof tiles next year, a recent patent has been published outlining a design that would allow the company to offer colored variants of the solar shingles without compromising any functionality.
Tesla’s recent patent, titled “Uniformly and Directionally Colored Photovoltaic Modules,” was published last Thursday. In the document’s background, Tesla noted that PV modules are usually blue, dark blue, or black because these are the natural color of solar cells. Considering that homeowners have preferences in their roofing material’s color, though, there is a need for the Solar Roof tiles to have varying shades and textures. There are currently several conventional ways to colorize PV modules, such the utilization of tinted glass and/or encapsulation sheets. That said, such systems are prone to absorbing large amounts of sunlight, which results in PV power loss. The appearance of standard colored PV modules also tends to degrade over time.
“Shading, or absorption of incident sunlight, causes PV power loss, a consequential problem of existing coloring techniques. In addition, colored PV modules manufactured with these techniques, and colored glass more generally, commonly suffer from: sparkle, or glint; flop, or angle-dependent color appearance; and graininess. Note that sparkle refers to glint or localized bright spots. Flop, on the other hand, usually refers to angle-dependent color, i.e. an angular dependence of the peak reflected wavelength. The term flop, or light-dark flop, can also refer to angle-dependent brightness, i.e. an angular dependence of total reflectivity.”

Tesla’s system for its colored Solar Roof tiles utilizes a rather clever system to avoid the drawbacks of conventional PV module coloration methods. Instead of using traditional solutions like tinted glass, Tesla’s design employs a texturized surface of a glass cover that has a color filter layer, as well as a “transparent material with a predetermined refractive index.” Following is Tesla’s description of its colored Solar Roof tiles’ design.
“Embodiments of the present invention can produce PV roof tiles with a uniform color with little light absorption. As a result, a high proportion of the incident light (of colors other than the module’s intended color) is transmitted to the PV cells. To facilitate uniform coloring of PV modules and roof tiles, the inside surface of a top glass cover can be texturized, and a transparent material with a predetermined refractive index or combination of refractive indices can be deposited on the texturized surface. Such a micro-textured or frosted glass cover can display significantly less sparkle, flop, and graininess than conventional glass covers, thus improving color uniformity and appearance. Customizable directional coloring, and intentionally controlled angle-dependent color, can provide further aesthetic options, while still performing efficiently for solar conversion. It is also possible to produce a layer of sphere-shaped metal nanoparticles on the inside surface of the glass cover.
“These nanoparticles can produce colors efficiently while absorbing little light. Another feature described herein is directional coloring of PV modules or roof tiles. The texturized surface of a glass cover can have a color filter layer covering one or more facets of the texture. This color filter can include multiple thin film layers formed using a directional thin film deposition technique, such as chemical or physical vapor deposition (CVD or PVD), e.g. sputtering. The coating layer can be deposited by coating the textured glass surface in one or more directions. Such directional coating can reduce unwanted light absorption by the color filter, while still providing a uniform color appearance to viewers at a certain viewing angle.”
Tesla opted to design the colored Solar Roof tiles with textured “micro-structured” glass, which feature surface roughness on the order of 100 nm to 10 μιη. This allows the colored Solar Roof tiles to display a uniform color with little light absorption and less sparkle, flop, and graininess than conventional colored glass. The colored shingles’ design also provides customizable directional and multi-directional coating, improving the aesthetics of the Solar Roof tiles themselves while still being optimized for solar conversion.
Following is a comparison of conventional colored PV modules (504 and 508) and Tesla’s coloration system (502 and 506), showing how the electric car maker’s micro-structured glass design addresses sparkle, or glare; flop, or angle-dependent coloring.
The Solar Roof tiles are Tesla’s flagship residential solar product. Designed to mimic the appearance of conventional roofing materials while offering all the advantages of solar panels, the Solar Roofs are an excellent way for homeowners to utilize a PV system without compromising the aesthetics of their home. The shingles were warmly received when they were unveiled back in 2016, though the production and installation of Solar Roof tiles are yet to ramp. Elon Musk explained the delay in the shingles’ production ramp during the third quarter earnings call.
“We’ll also start going into volume production of the solar tile roof next year. That’s quite a long development cycle for — because anything that’s roof has got to last 30 years. So even if you do accelerate life testing as fast as possible, there’s still a minimum amount of time required to do that. And there’s a lot of engineering that goes into how do you put on the solar tile roof with a — and not be really labor-intensive in doing so. So there’s a lot of engineering not just in the tile but in the way it’s done,” Musk said.
Back in July, Tesla CTO JB Straubel noted that the company is “aggressively” ramping its capacity to produce and deliver its residential solar products, stating that “No one should see us as stepping back from solar. In fact, it’s the opposite. It’s like with Model 3. People have come flooding in and are waiting on the product. So now we’re aggressively ramping our capacity.”

According to the official goods and services description in the application, Tesla describes ‘MEGAPOD’ as:
“Modular data center hardware systems for artificial intelligence computing, comprised of computer servers, computer hardware for artificial intelligence processing, computer networking hardware, electrical power distribution units, and cooling systems, sold as a unit; self-contained modular computing hardware systems for artificial intelligence workloads; integrated computer hardware platforms for artificial intelligence computing, namely, enclosures containing computer hardware, power distribution hardware, and cooling hardware, sold as a unit; downloadable software for monitoring, managing, optimizing, and regulating modular artificial intelligence computing hardware systems.”
This description specifies complete, self-contained modular units that integrate servers and specialized AI processing hardware with networking components, power distribution, and cooling systems. It also includes associated downloadable software for oversight and optimization of these systems. The language emphasizes hardware sold “as a unit” and enclosures that combine the necessary elements for AI computing workloads.
Tesla has an established history of developing and commercializing modular hardware systems. Its Megapack product line, for example, consists of utility-scale battery energy storage systems designed as containerized units for grid applications. The MEGAPOD filing follows a similar pattern of protecting a name for modular, integrated hardware platforms, this time focused on artificial intelligence computing infrastructure.
This could be an early move, especially as Tesla did not have trademark rights to the word ‘Cybercab,’ the name of its self-driving, ride-hailing-focused vehicle.
Trademark applications of this type allow companies to secure priority rights to a name for defined categories of goods and services. The USPTO examines applications for compliance with legal requirements, including distinctiveness and absence of conflicts with prior marks. If the application proceeds successfully through examination, publication, and any opposition period, it could result in a federal trademark registration providing nationwide protection. This is what Tesla’s obvious intention is with ‘MEGAPOD.’
Public reports and analysis suggest MEGAPOD could represent modular, container-style AI computing pods designed for easy deployment. These would bundle servers, AI accelerators, power systems, and cooling into self-contained units suitable for distributed AI workloads. This approach aligns with Tesla’s announced AI compute strategy.
In March 2026, Elon Musk outlined plans for “Digital Optimus” (also referred to as Macrohard), a joint Tesla-xAI project for AI agents capable of handling complex digital tasks. The plans include running these agents on Tesla’s AI4 hardware in parked vehicles as well as dedicated compute units installed at Supercharger stations, which collectively offer substantial unused electrical capacity.
What is Digital Optimus? The new Tesla and xAI project explained
A modular hardware platform like the one described in the ‘MEGAPOD’ filing would support scalable, rapid deployment of such distributed compute resources. It could complement Tesla’s other AI infrastructure efforts, including the Dojo supercomputer used for training models and the development of AI systems for autonomous driving and robotics, by enabling edge or regional AI inference without reliance on traditional centralized data centers.
In a notable intersection of Big Tech powerhouses, Meta, led by Mark Zuckerberg, has partnered with Canadian energy infrastructure giant Enbridge on a significant renewable energy initiative that will rely on battery technology from Elon Musk’s Tesla.
The project, which was announced this week, marks another step in Meta’s aggressive push to power its expanding data center operations with clean energy, dispelling many of the complaints people have about them.
This new development is located near Cheyenne, Wyoming, and will feature a 365-megawatt (MW) solar farm paired with a 200 MW/1,600 megawatt-hour (MWh) battery energy storage system, also known as BESS. Tesla is providing the batteries for the project, valued at roughly $200 million.
The story was originally reported by Utility Dive.
This Wyoming project represents the first phase of Enbridge and Meta’s joint “Cowboy Project.” Once operational, it will deliver power to Meta’s regional data centers through Cheyenne Light, Fuel, and Power under Wyoming’s Large Power Contract Service tariff.
This tariff, originally developed in collaboration with Microsoft and Black Hills Energy, is designed specifically for large loads like data centers. It ensures that the renewable supply serves hyperscale customers without impacting retail electricity rates for other users.
The battery system will operate under a long-term tolling agreement, providing dispatchable capacity that enhances grid reliability. During periods of high demand, the utility can access the backup generation, addressing one of the key challenges of integrating large-scale renewables with the explosive growth of data center electricity demand driven by artificial intelligence.
This latest collaboration builds on prior joint efforts between Enbridge and Meta in Texas, including the 600 MW Clear Fork Solar, 152 MW Easter Wind, and 300 MW Cone Wind projects. Together with the Wyoming initiative, the companies have now partnered on roughly 1.6 gigawatts (GW) of combined solar, wind, and storage capacity.
The deal highlights the intensifying demand for reliable, low-carbon power from technology giants. Meta has committed to supporting its data center growth with renewable energy, joining peers like Microsoft and Google in seeking large-scale solutions. Enbridge’s Allen Capps described the project as “one of the larger utility-scale battery installations supporting U.S. data center operations and growth.”
The involvement of Tesla’s battery technology adds an intriguing layer, linking two of the world’s most prominent tech leaders—Zuckerberg and Musk—in the clean energy transition.
As data centers continue to drive unprecedented electricity load growth across the United States, projects like this one illustrate how hyperscalers are turning to strategic partnerships with traditional energy players and innovative storage solutions to meet both sustainability goals and reliability needs.

Why SpaceX just made a $60 billion bet on AI coding ahead of historic IPO
SpaceX has secured an option to acquire Cursor AI for $60 billion ahead of its historic IPO.
SpaceX announced today it has struck a deal with AI coding startup Cursor, securing the option to acquire the company outright for $60 billion later this year, while committing $10 billion for joint development work in the interim. The announcement described the partnership as building “the world’s best coding and knowledge work AI,” and comes just days after Cursor was separately reported to be raising $2 billion at a valuation above $50 billion.
The move makes strategic sense given where each company currently stands. Cursor currently pays retail prices to Anthropic and OpenAI to the same companies competing directly against it with Claude Code and Codex. That means every dollar of revenue Cursor earns partially funds its own competition. With SpaceX bringing computational infrastructure to the Cursor platform, that could reduce Cursor’s dependence on OpenAI and Anthropic’s Claude AI as its providers. Access to SpaceX’s Colossus supercomputer, with compute equivalent to one million Nvidia H100 chips, gives Cursor the infrastructure to run and train its own models at a scale it could never afford independently. That one change restructures the entire unit economics of the business.
Elon Musk teases crazy outlook for xAI against its competitors
Cursor’s $2 billion in annualized revenue and enterprise reach across more than half of Fortune 500 companies gives SpaceX something its xAI subsidiary currently lacks, which is a proven, fast-growing software business with real enterprise distribution.
For Cursor, SpaceX’s $10 billion in joint development funding is transformational. Cursor raised $3.3 billion across all of 2025 to reach that $2 billion in revenue. A single $10 billion commitment from SpaceX, even as a development payment rather than an acquisition, dwarfs everything Cursor has raised in its entire existence. That capital accelerates product development, enterprise sales infrastructure, and proprietary model training simultaneously.
The timing is deliberate. SpaceX filed confidentially with the SEC on April 1, 2026, targeting a June listing at a $1.75 trillion valuation, in what would be the largest public offering in history. The company is expected to begin its roadshow the week of June 8, with Bank of America, Goldman Sachs, JPMorgan, and Morgan Stanley serving as underwriters. Adding Cursor to the portfolio before that roadshow gives IPO investors a concrete enterprise software revenue story to price in, alongside rockets and satellite internet.
The deal also addresses a weakness that became visible after February’s xAI merger. Several xAI co-founders departed following that acquisition, and SpaceX had already hired two Cursor engineers, signaling where its AI talent strategy was heading. Cursor, for its part, faces a pricing disadvantage competing against Anthropic’s Claude Code.
Whether SpaceX exercises the full acquisition option before its IPO or after remains the open question. Either way, this deal reshapes what investors will be buying into when SpaceX goes public.
