Tesla Solar Roof is becoming a stealthy killer, and no one is standing in its way
Tesla executives like CEO Elon Musk may emphasize that the company’s Energy business is just as important as its electric vehicle division, there is little doubt that stationary batteries and solar products are just not as sexy or exciting as, say, all-electric supercars, futuristic pickups, or Full Self-Driving software. Yet as Tesla Energy hits its stride, it is becoming evident that some of the company’s products like the Solar Roof could very well develop into stealthy disruptors on their own.
Tesla Energy’s flagship solar product is the Solar Roof, which was initially unveiled in 2016. Since then, the attractive solar shingles have not really seen a serious ramp, at least until now. Over the following years since its debut, Tesla focused on optimizing and improving the Solar Roof, and the result of these initiatives was the V3 tiles, which were rolled out last year. Tesla’s Solar Roof installations have been steadily ramping then, but just like the company’s energy division, its growth was mostly in the background.
Prior to the third-quarter earnings call, Tesla Energy made headlines after roofing company Weddle and Sons Roofing announced that it was able to complete a full Solar Roof installation in just four days. The project was no joke either, as the system was comprised of 15 kW of Solar Roof tiles that covered about 4,000 sq.ft. (about 372 sq.m). This was a milestone for the company, but as noted by Tesla in its Q3 2020 Update Letter, this installation was not even the fastest to date.
Tesla revealed in its third-quarter Update Letter that it has been able to complete a full Solar Roof installation in just 1.5 days. The company did not indicate the size of the system, though it did provide images depicting the installation’s progress. This update, together with the recent report from Weddle and Sons Roofing, shows that steadily, Tesla’s Solar Roof tiles are becoming faster and easier to install.
Tesla Energy’s growth in the third quarter was incredibly impressive, with the company deploying 57 MW of solar, a 111% growth from the second quarter. The company also announced that 759 MWh worth of battery storage was deployed, an 81% increase from Q2 2020. These milestones tend to be pushed aside by the company’s FSD and EV developments, but if Tesla Energy continues at this pace, it would only be a matter of time before the company’s solar and battery storage systems end up becoming a force that will be incredibly difficult to ignore.
Interestingly enough, the Tesla Solar Roof does not really have a lot of competition in the residential solar market in the United States. Granted, products like the SunTegra Solar Shingles could provide some competition, but the overall lineup of rivals for the electric car maker’s V3 tiles are relatively few. With this in mind, the potential path to dominance for the Tesla Solar Roof seems to be mostly clear. Tesla just has to produce them at volumes that meet demand.
Tesla’s reach into the residential market has actually been growing. EnergySage’s eleventh semiannual Solar Marketplace Intel Report, for one, concluded that the Tesla Powerwall 2 is pretty much dominating the US residential market for stationary storage. The competition, comprised of battery storage units from companies like LG Chem, lie far behind, with the Powerwall dominating about half of the quotes given in EnergySage’s Marketplace.
Elon Musk spoke about the Solar Roof’s potential in Tesla’s recently-held earnings call. Just like before, Musk was optimistic about the shingles, though this time around, the CEO seemed to be more certain about its upcoming disruption. Musk even remarked that the Solar Roof’s status as a “killer product” will become evident next year.

“When you look around the neighborhood in the future, decade from now, what do you want? What products are going to make your life better? What future do you want? And I think a future where we’ve got beautiful roofs generating energy that are tough and resilient and better in every way than a regular roof and alive with energy, that’s the future we want. Solar Roof is a killer product. This will become obvious next year,” he said.
In a new note to investors on Tuesday, Morgan Stanley analyst Andrew Percoco said that Tesla has one big financial question to answer for investors regarding its Robotaxi rollout, Full Self-Driving software, and Optimus.
Percoco said in the note that, for the most part, investors are still very positive about the direction the company is headed. However, there are some things the firm would like to see, and they have to do with financials.
Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Tesla bulls are more than convinced that the company’s Full Self-Driving software is proof it can develop physical AI. Financially, however, there are still some questions, especially on elevated spending, which CEO Elon Musk said would occur as the company works to roll out Robotaxi faster and continue developing its Optimus robot.
The latter two are where Tesla will have to prove progress to investors, as Percoco writes that both projects “will require clearer evidence that Robotaxi is scaling and more tangible Optimus proof points to support the ROI on elevated capex.”
Percoco said the second quarter earnings call did not change his long-term thesis of where Tesla is positioned in the AI race, which is out in front. However, there are concerns that weaker gross margins and higher R&D spend will stress financials, and that has “sharpened our (and investors’) focus on measurable progress across Robotaxi and Optimus.”
Additionally, Robotaxi still needs to be proven with more operation in existing cities while maintaining safety but improving how many rides it gives in any given time, he said. For Optimus, Percoco wrote that he is “still looking for evidence beyond commentary around SOP.”
Morgan Stanley put Percoco in charge of covering Tesla after long-time analyst Adam Jonas transitioned to the automotive side.
Currently, Morgan Stanley has a $415 price target on Tesla and a ‘Hold’ rating on the stock. It is trading at around $330 at the time of publication, which was 2:30 P.M. on the East Coast.
SpaceX’s massive investment in AI will make it a big winner, Argus Research said after the company’s successful earnings call last week.
The firm also upgraded shares to a Buy from Hold and set a $160 price target.
SpaceX (NASDAQ: SPCX) is currently recovering from its heavy AI infrastructure investments, as it spent nearly $16 billion in Q2 alone. The company did this primarily by monetizing high-demand GPU compute capacity at a much faster pace than traditional data center economics would suggest.
Company CFO Bret Johnsen said that SpaceX would be able to pay back anything on new deployments within a year.
There are plenty of ways the company can do this:
Leasing excess compute capacity through contracts
SpaceX has already built Colossus and Colossus II, largely for its own model training. However, much of that capacity is already rented out to third parties. It already has major deals with Anthropic, Google, and Reflection AI. These partnerships are adding billions per month to SpaceX’s spreadsheet.
High utilization driven by industry-wide scarcity
The demand for advanced AI training and inference capacity continues to exceed what is available for use. SpaceX can fill new racks quickly after they come online, so the capital deployed converts into revenue with minimal idle time.
Additionally, management and outside observers have described the new compute capital as behaving more like a cost-of-goods-sold than traditional multi-year capex, especially because of this rapid monetization pattern.
Capacity has already scaled from ~0.4 GW a year to 1.4 GW annually by the end of Q2. There are targets of more than 2 GW by year-end.
High incremental margins on the rental business once capacity is online
GPU cloud providers often operate at strong gross margins. SpaceX can monetize capacity that was already partially built or can be added efficiently. This means that incremental EBITDA margins on the rental revenue are usually high. This accelerates cash recovery relative to the gross capital outlay.
Parallel monetization of its own AI software and applications
Beyond pure infrastructure rental, SpaceX also generates revenue from Grok through subscriptions and usage, from X through ads, data, and other related services, enterprise APIs, and the planned integration of the Cursor coding tools acquisition.
These application layers ride on the same compute infrastructure and provide additional high-margin streams that could offset build-out costs. AI-segment revenue overall rose sharply to about $2.6 billion in Q2, according to Motley Fool. This was driven primarily by the infrastructure contracts, but the software side is also partially responsible.
Efficient, large-scale deployment and vertical integration advantages
SpaceX has emphasized the rapid construction of power and cooling infrastructure and favorable cost-per-megawatt economics relative to industry benchmarks in some disclosures.
Combined with its ability to scale capacity aggressively and the fact that many contracts start generating revenue within months of capacity coming online, the effective payback compresses dramatically compared with more conventional multi-year data-center projects.
SpaceX’s dominant near-term recovery path will turn the AI clusters into a hyperscale-style compute rental business for other leading AI companies while still using a portion for internal models.
Tesla headlights have caused a recall of over 20,000 of the company’s two most popular vehicles, the Model 3 and Model Y, due to the low-beam bulb exceeding the maximum allowed intensity according to federal standards.
Tesla initiated the recall with the National Highway Traffic Safety Administration (NHTSA) this morning, stating that the low-beam output “exceeds the maximum allowed intensity in the outer upper-right and outer upper-left areas of the 10U and 90U zone, as prescribed in FMVSS No. 108.”
Tesla sourced the impacted headlights from Marelli Automotive Lighting, a Mexico-based company. The recall impacts 2020-2023 Model Y vehicles and 2017-2023 Model 3 vehicles. It is estimated that every VIN in this recall is impacted by the defect.

Typically, Tesla would remedy recalls of this nature through an Over-the-Air software update, which has been a major focus of criticism by the company and its supporters because the NHTSA still refers to it as a “recall,” even though it requires no action by the vehicle owner. The fix is shipped over the internet and downloaded to the car.
However, there appears to be a potentially different solution for this problem. Tesla has not developed a remedy for this issue, so it could potentially be on the way. The big issue appears to be the fact that these recalled lamps are out of production, and this is an old body style for both vehicles. The headlights and front-end designs are completely different.
Tesla switched to another supplier when the affected headlight design was discontinued. It plans to begin notifying owners of their remedy options by September 15.
Tesla filed a petition protesting the recall to fix the vehicles’ headlight issue, but the NHTSA denied it. Now, Tesla will come up with a solution to fix it.
