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.

SpaceX’s next Starship launch is about to attempt its biggest leap yet
SpaceX targets September 22 for Starship Flight 14, its first attempt to reach real orbit.
SpaceX has set September 22 as the target date for Starship’s 14th test flight, and this one carries a different goal than any of the 13 that came before it. Every previous Starship mission has intentionally flown a suborbital arc, reentering the atmosphere within the same hour it launched. Flight 14 is designed to send the craft into a genuine orbit around Earth for the first time.
The launch window opens at 7:15 a.m. Central time at Starbase in South Texas and runs for 75 minutes, pending regulatory approval, according to SpaceX’s mission description published Tuesday. If the flight goes as planned, Starship will circle the planet roughly six times at an altitude near 275 kilometers over about ten hours before a deorbit burn sends it toward a splashdown in the Pacific Ocean west of Chile, a departure from the Indian Ocean recoveries used on the last several flights.
The mission also marks the first attempt to put a working batch of Starlink V3 satellites into actual service. Flight 13 carried 20 of the new satellites in July, but because that mission never left a suborbital trajectory, the payload reentered along with the ship instead of separating into orbit.
SpaceX tells the FCC that Starship Flight 14 is going to orbit
Each V3 satellite is rated for roughly one terabit per second of downlink capacity, so a successful deployment on Flight 14 would be SpaceX’s largest single jump in network bandwidth since Starlink began flying on Falcon 9.
Flight 13 still did the heavier lifting on the technical side. That July mission flew a deliberately more stressful reentry profile to test Starship’s heat shield, and the ship survived its softest splashdown yet, intact enough for drone inspections shortly after landing. Elon Musk said the flight delivered “all the heat shield data we needed and then some,” a result Teslarati covered in detail when he later said SpaceX had solved the vehicle’s biggest reusability challenge. Flight 14 is where SpaceX starts spending that confidence on an actual orbital insertion rather than another controlled fall back to Earth.
One thing Flight 14 will not attempt is a tower catch of the ship. Musk floated the idea right after Flight 13, but walked the timeline back in August, saying a catch attempt was more likely “in a few months.” The Super Heavy booster will still aim for its own recovery, targeting an offshore landing point in the Gulf of America, the same approach used on recent flights.
September 22 is SpaceX’s own target, not a locked date. Starship’s schedule has slipped before over hardware readiness and FAA sign off, and the company has said as much in its own mission notes. But the plan itself represents the clearest marker yet that Starship is moving from a suborbital test program into something meant to carry paying payloads and, eventually, people.

Elon Musk gives his most telling Tesla-SpaceX merger conversation yet
Elon Musk hinted a Tesla-SpaceX merger could be coming, and Wall Street is taking notice.
Elon Musk gave his clearest signal yet that Tesla and SpaceX could eventually combine, telling the All-In Summit in Los Angeles that the two companies’ deepening collaboration makes the question worth asking. Sawyer Merritt first surfaced the highlight on X Tuesday.
Asked directly why Tesla and SpaceX remain separate given how closely they already work together, Musk told hosts at the summit: “Great question there. With all this collaboration, on so many levels, who can imagine what action one might take when there’s so much close collaboration in so many areas.” SpaceX President Gwynne Shotwell, who joined Musk on stage, added that SpaceX personnel have already moved into xAI to fill leadership and engineering gaps, saying the businesses are integrating “faster than I thought,” though “not fully integrated yet,”
The comments landed on top of merger speculation that has been building on Wall Street for months. JPMorgan has called a tie-up “strategically coherent on paper,” pointing to overlapping ambitions in AI, robotics, energy, transportation and space. Jefferies went further, estimating Musk could retain roughly 55.3 percent voting control in a deal structured without a premium, a scenario that would still leave room for Tesla shareholders to come out ahead. On Kalshi, traders now put the odds of a merger before 2028 at 66 percent.
Tesla’s stake in SpaceX, still under one percent, traces back to its earlier investment in xAI, which converted to SpaceX equity after SpaceX absorbed the AI company. The two are also jointly building Terafab, a chip facility in Austin meant to serve both Tesla’s AI computing needs and SpaceX’s satellite ambitions. Wedbush analyst Dan Ives has stood by a 2027 merger timeline for months, and Cathie Wood’s ARK Invest recently floated a similar case, an idea Musk pushed back on directly at the time.

The timing adds another layer. Tesla has scheduled an October 1 unveiling for its next generation Roadster at a venue near SpaceX’s McGregor, Texas test site, using the phrase “Go for launch” in its promotional material. Both stocks dipped roughly 2 percent Monday before recovering slightly in premarket trading Tuesday, with SpaceX shares up about 0.4 percent and Tesla essentially flat.
Musk stopped short of confirming anything is in motion. But unlike his past denials of a corporate restructuring, this response didn’t rule one out, and it came with Shotwell sitting next to him describing an integration that’s already underway.

Tesla Roadster unveiling is getting hyped up by Elon Musk
The Tesla Roadster unveiling is getting hyped up by the company’s CEO Elon Musk, who has been a big reason the product has such high expectations due to delayed timelines and a constant need to make it even more insane than before.
Tesla announced on September 12 that it would officially unveil the Roadster in Waco, Texas, on October 1, ending years of patience for fans and reservation holders who have waited for the all-electric supercar to enter production since 2017.
Musk has said that this event will be well worth the wait on several occasions, and last year on the Joe Rogan Experience, he said that there should be a closing chapter to supercars- the end of cars that aren’t focused on safety.
He said:
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one. I think it has a shot at being the most memorable product unveil ever. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”
Musk’s teases have continued, and now that the event is roughly two weeks away, it seems like Roadster is finally going to show up and blow some minds:
It’s out of this world

Excitement guaranteed

Tesla has definitely dragged out the development of the Roadster, but there is a good reason for it.
Tesla has been working on many other projects, most notably self-driving efforts to increase passenger safety, and those simply took priority over the Roadster, a low-volume, high-performance sports car that has a lightning-fast acceleration rate of 0-60 MPH in just 1.1 seconds, could potentially fly, and contributes very little to the company’s mission.
However, many people have the Roadster on pre-order through the referral program or with their own money, and it is time that Tesla delivers on that.
