Tesla patent reveals Solar module aimed at faster, more attractive installations
Tesla Solar may have taken a step back from the limelight in recent years due to the electric car maker’s efforts to ramp the Model 3 sedan, but recent signs from the company indicate that it is now ready to start aggressively pushing its Energy business. Apart from high-profile projects such as the 50% expansion of the Hornsdale Power Reserve, Tesla also appears to be working on notable improvements to its residential solar system installation processes.
One such improvement was outlined in a recent patent application titled Method and apparatus for mounting photovoltaic modules. The patent describes a novel mounting system for photovoltaic modules that make them easier to install, maintain, and even remove if necessary. Tesla notes that its patent allows solar panel installations to be more aesthetically pleasing than traditional PV setups as well.
In its discussion, Tesla explained that solar panel installations are usually hit by a number of challenges, particularly in terms of alignment, grounding, wiring, rafter connections, and several other factors related to the mounting of the PV system itself. With this in mind, Tesla stated that there is a clear need for a PV module mounting system that is simple, cost-effective, and widely adaptable.
To address these challenges, Tesla has come up with an invention that utilizes an interlocking photovoltaic module mounting system. This design provides a “one piece, integrated photovoltaic module frame portion that is directly mountable to a support structure and interlocks with separate adjoining photovoltaic module frame portions.”
“A preferred embodiment of the invention includes an interlocking mechanism comprising at least one C-shaped channel portion on the outside surface of the PV module frame member with the opening oriented parallel to the plane of the substantially flat top solar cell covering, and which interlocks with an identical adjoining C-shaped channel portion of an adjoining PV module frame member through the use of a separate male coupling member which is inserted into the C-shaped portions of the two adjoining modules. The adjacent C-shaped channel portions do not overlap each other. The male coupling member may also serve as a means for providing electric ground continuity between PV modules,” Tesla wrote.
Such a system would offer a variety of benefits for Tesla and homeowners. Among these benefits include potentially faster installation processes, easier maintenance, and even simpler removal, to name a few. Utilizing the design outlined in Tesla’s patent, the electric car maker further explained that solar installations would look better, since the mounting systems provide no gaps between modules. Such a system will likely not make regular solar panel installations as attractive as, say, a Tesla Solar Roof installation, but it does allow for a very sleek overall look.
“The inventive system thus provides an interlocking, self-grounding, and self-aligning framing structure for each module, which provides three-dimensional adjustability, allows simple connection to the rafters, minimizes penetrations in the roof, allows access to wiring interconnects without removing modules, does not require expensive strut hardware, utilizes a non-overlapping, interlocking mechanism which allows for all PV modules in an array to rest in the same plane instead of having consecutive modules at slightly different angles due to the overlapping nature of an interleaved connection, and which in some embodiments allows removal of single PV modules from the middle of the array.
“The inventive system also provides an attractive appearance by having a low profile, with no gaps between modules, and no visible hold-downs or hardware, plus optional cosmetic flashings for screening visible edges of the array and optional cosmetic caps for covering the small gaps that may occur, or in one embodiment, for bridging between two adjacent PV modules to cover the wiring. Additional benefits are further described herein,” Tesla noted.
Promoting solar installations to homeowners is a key component of Tesla Energy’s business. And to gain an advantage in the residential solar market, Tesla would need to ensure that its PV installations are worthy of its premium brand while being cost-effective overall. Tesla’s electric cars are a cut above the rest of the market and thus, the expectations for its energy business are high. With such ideas as presented in this recently published patent application, it would appear that Tesla is actively exploring ways to improve its residential solar initiatives, even down to their mounting system.

Elon Musk has publicly questioned Moody’s credit assessments following the rating agency’s decision to assign SpaceX a Baa1 investment-grade rating, two notches above Tesla’s Baa3. The comments came amid discussions comparing the two companies’ financial profiles.
SpaceX earned its first-time Baa1 rating with a stable outlook from Moody’s. The agency highlighted the company’s leadership in orbital launches, the growing recurring revenue from its Starlink satellite network, strong vertical integration, U.S. government contracts, and emerging opportunities in AI infrastructure.
These factors were cited as supporting robust cash flows, margin expansion, and financial flexibility.
Musk responded directly: “Tesla’s credit rating is ridiculously low tbh,” and added, “Yeah, makes no sense. Tesla has over $40B in cash, no debt, and is consistently profitable!” His remarks underscored Tesla’s balance sheet strength and profitability at a time when many traditional automakers continue to report losses in the shift to electric vehicles.
Yeah, makes no sense.
Tesla has over $40B in cash, no debt and is consistently profitable!

Tesla maintains a leading position in the global EV market, with diversification into energy and storage, battery technology, and robotics through projects like Optimus. Recent financial updates show the company generated positive free cash flow of $1.4 billion in Q1 2026, supported by operating cash flow of $3.9 billion. Cash and short-term investments stood at approximately $44.7 billion.
Moody’s has affirmed Tesla’s Baa3 issuer rating with a stable outlook in periodic reviews, acknowledging the company’s EV leadership, technology strengths, including AI for autonomous vehicles, solid profitability, and strong liquidity.

However, the agency has also noted challenges in the automotive segment and expectations for margin pressures.
Musk’s critique highlights a common debate about how traditional rating methodologies apply to high-growth, capital-intensive technology companies. SpaceX benefits from long-term government-backed contracts and diversified, recurring revenue streams, while Tesla’s valuation reflects heavy investment in future technologies such as autonomy and robotics.
Both ratings remain investment-grade, yet the one-notch difference has fueled online discussion about potential inconsistencies in evaluating innovative firms.
The exchange comes as SpaceX explores financing options following its recent valuation milestones, while Tesla continues executing on its multi-year roadmap. Musk’s pointed response serves as a reminder that credit ratings, though influential for borrowing costs, represent one lens through which markets assess corporate strength—and that company leaders often view their financial positions through the lens of long-term innovation and cash generation rather than short-term risk metrics alone.
A new report from Reuters claims that a transport authority in Sweden is pushing back against the approval of Tesla’s Full Self-Driving suite because it will travel over speed limits.
The report says the Swedish Transport Administration (TRV) recommends the European Union votes against FSD’s approval. TRV believes it should not be approved until Tesla disables FSD’s ability to speed.
TRV sent a letter to the European Union’s Technical Committee on Motor Vehicles (TCMV), which is set to meet on June 30 to discuss the potential approval of the Tesla FSD suite in the country. Tesla, which has received various approvals in Europe over the past two months, has not provided a comment.
Teslas operating on FSD do travel over the speed limit, depending on the Speed Profile that is chosen. Drivers have the ability to disengage FSD at any point; Tesla specifically states that those supervising the suite are responsible for its actions.
Let’s cut to the chase: humans operating any vehicle speed almost daily in the United States. Realistically, speed limits in the U.S. are more frequently treated as speed minimums. However, other countries are different, and driving behaviors are less aggressive.
TRV believes that “allowing automated systems to systematically exceed legal speed limits…risks undermining both the legal framework and the expected safety benefits of vehicle automation,” the report stated. It’s surprising that Tesla has not received this claim from other countries previously.
This could be a good argument to bring Max Speed back, the setting that previously allowed the driver to choose the absolute fastest the car would travel.
This would still put the responsibility of supervision in the hands of the driver. It would allow the driver to choose whether the car would travel over the speed limit or not, acknowledging that they set the speed, and if they get pulled over, there would be no ability to argue it.
However, it does not seem as if this is something Tesla will do, especially considering many U.S. drivers have requested the feature in an effort to eliminate speeding or at least tone it down. The company has not shown any interest in bringing it back.
Tesla has approvals for FSD in Europe in Estonia, Lithuania, Denmark, the Netherlands, and Belgium.
Tesla is going to let you guide Full Self-Driving with Grok in 3 months, CEO Elon Musk confirmed on X.
The response from Musk, which revealed Tesla plans to allow drivers to effectively control the car and its navigation more explicitly using Grok, puts the feature for about September.
A Tesla owner said that Full Self-Driving is great, but owners should be able to “converse with Grok like we can with an Uber driver.” She then used examples like, “Grok, turn right here,” and “Drop us off right here, we’ll walk due to traffic,” and finally,” Drop at entrance first, then park far away.”
Coincidentally, the final piece of dialogue would also mean features like Banish are potentially on the way soon.
This functionality will be there in about 3 months or so

Banish is also referred to as “Reverse Summon,” and would enable the car to self-park while dropping occupants off at their destination.
This would be a great way to improve the overall experience while supervising FSD. Navigation is already a major painpoint that many owners complain about. Manual overrides when a maneuver is requested or canceled (like using the turn signal stalk to override a navigation route), do not always work.
The feature could be especially useful in street parking scenarios in a city, where spots are sometimes tough to come by. Many of us who grab dinner in a more populated area will park a street or two over from wherever we’re going, because sometimes you know that’s the best you will get. If a driver using FSD could say, “Hey Grok, turn right here on Queen St. and park in that open spot on the right,” it could save a lot of confusion FSD might have on its own.
Musk teased that a similar feature was “coming” back in February:
Tesla Full Self-Driving set to get an awesome new feature, Elon Musk says
It is certainly surprising that Tesla is doing it at this point. The company’s more recent moves have been more evident of taking control and inputs away from humans and putting them in the AI’s hands more frequently. The biggest example of this was taking away Max Speed in AI4 cars, giving us Speed Profiles, and not having any input on the fastest speed the car will travel.
Of course, giving navigation preferences to Grok is availble already in Teslas, but not at the drop of a hat. Instead, you can suggest a certain route at the beginning of your drive.
Here’s an example of that from December:
🚨🏈 I am taking my parents and Fiancee to the @Ravens game next weekend and asked @Grok to help me route my @Tesla through a specific neighborhood to reach the correct Lot we will park in.
This is a great example of the new @grok nav integration with the Tesla Holiday Update: pic.twitter.com/rPp4I7q8Yv
— TESLARATI (@Teslarati) December 13, 2025
Finally, the original post that Musk responded to mentioned a parking preference after dropping off the occupants, which describes the Banish feature that Tesla has teased for years.
We’re not sure if Musk was responding more to the ability to guide the car with Grok, or whether he also was including Banish in the three-month prediction timeframe.
