There is another attempt to create a solar-powered Tesla. DartSolar is pitching a drivable solar array to self-charge your car. Companies are experimenting with this concept, aiming to enhance the sustainability and self-sufficiency of EVs. A solar-powered Tesla would be amazing, no doubt. But it isn’t happening. That is not this writer's opinion, but the guy who may be the biggest fan of both solar and Tesla: Elon Musk.
A New Solar Addition for Tesla
Taking on the challenge is an ambitious company working on the "drivable solar array," currently in beta, designed to self-charge EVs. The company uses a Tesla Model Y test vehicle with nine large solar panels. The website states that “Beta One is light enough to be carried on the roof rack of your EV. It weighs less than 165 lbs. When expanded, it fits in a standard parking spot.”
Beta One features flexible solar panels without junction boxes, allowing for flat shipping and simple assembly into four sections. Projected to be priced at $4,000 USD and using nine 175-watt panels, Beta One claims to generate 6 kWh daily, providing about 20 miles (32 kilometers) of EV range with five hours of sunlight.
Payback on Investment
The amount of energy generated and range gained on an EV with these panels will obviously vary depending on the location, weather, and the vehicle, but how long would it take to recoup the initial investment? Without taking into account any range decrease due to the reduced aerodynamics and increased weight, owners would be looking at about $0.97 USD in daily savings (based on 16.21 cents per kWh average in the U.S.) when using these solar panels.
Before you even take into account the look of the vehicle, the added maintenance, and potential issues, owners would be looking at more than 11 years before making back their initial investment of $4,000.
That’s not to say this project doesn’t have its benefits and use cases. If you’re in a remote location with little access to electricity, this could be an interesting idea, however, it’s not going to make sense for most consumers. Solar requires a lot of space and right now it just makes more sense on a large open area instead of being strapped to the top of a moving vehicle. However, projects such as these continue to push innovation and outside-of-the-box thinking.
Musk recently posted on X: "Earth already receives about the same energy from the Sun in an hour than humanity consumes in a year. Solar panels just need to catch a tiny amount of it to power our entire civilization!" Despite acknowledging the immense potential of solar energy, Musk remains doubtful about its application in EVs due to limited surface area. In this video clip, he gives a simple explanation for his 2021 appearance with Joe Rogan.
Aptera's Solar Electric Vehicle: A Case Study
Aptera Motors continues to face the challenge of creating a solar-powered vehicle. The San Diego start-up has been raising funds for a few years to produce its unique, three-wheel sun-powered car. This vehicle can travel up to 1,000 miles on a single charge, up to 40 miles powered solely by solar energy.

Tesla signaled its intention to launch its first Robotaxi network in Austin, Texas, with company-owned and operated vehicles, back in January. This network will be Tesla’s first foray into truly autonomous vehicles - ones that aren’t being directly supervised by a driver. Later in February, Tesla’s executive team confirmed that the plans were on track for the launch of the Austin network both on X and during several interviews that they participated in.
At the end of February, we also found out that Tesla has applied for a Supervised Robotaxi license in California, where the network will also launch, but with safety drivers in place.
This is an ambitious plan, but FSD has really come a long way in the past year. FSD V12 was a massive step forward from V11, and V13 has made the experience smoother and safer than ever before. FSD V14 is expected to be another big step up with auto-regressive transformers and audio input.
Still on Track
Now, Elon has tripled down on the fact that Tesla will be launching their first autonomous robotaxi network in Austin - just two months away at this point. It seems that Tesla is fully set to launch their first fully unsupervised self-driving vehicles that will carry paying passengers in June.
Additional Cities
The best part is that Elon also confirmed that they’re targeting robotaxi networks launching in many cities within the United States by the end of this year. However, remember that this will be a Tesla-run network at first - Tesla owners won’t be able to add their vehicles to the Robotaxi fleet right away.
Adding Customer Vehicles
It will take some time before Tesla meets their strict internal safety requirements before it lets customers add their own vehicles to the network. Tesla’s executive team mentioned that they intend to let owners add their own vehicles to the fleet sometime in 2026. This happens to be the same time frame that Tesla plans to launch the Robotaxi across the United States, Mexico, and Canada — something that could only be done with customer-owned cars.
That final step will be bold—and it may come with complications, especially given that autonomous vehicle approval spans municipal, state or provincial, and even federal levels. There are plenty of regulatory hurdles ahead, but this is undoubtedly shaping up to be one of the most exciting times for Tesla.
Launch Event
With the Robotaxi network launching and Unsupervised FSD just around the corner, there’s a lot to get excited about. Tesla is expected to host a launch event at Gigafactory Texas in Austin to mark the debut of its first Robotaxi network. The company previously hinted that referral code users could receive invites—offering a rare chance to score an early ride in a Robotaxi outside the Hollywood studio lot.
Tesla’s engineering mule vehicles—used to test autonomy for future platforms—have resurfaced after an extended absence. The last time we saw them was back in July, when Tesla was gearing up for its initial We, Robot event. Since then, sightings have been scarce.
These vehicles typically signal that Tesla is testing new camera placements or validating FSD ground-truth data. This time, however, they appear to be outfitted exclusively with the updated camera hardware seen on the Cybercab.
New Sightings
The mules have now been spotted in Boston, Massachusetts, and Concord, New Hampshire—their first known appearances this far east. This suggests Tesla is actively collecting data to evaluate and optimize FSD performance in new regions. Thanks to Reddit user Ready_Medium_6693 for catching the one in Concord.
Elon Musk recently mentioned that Tesla plans to expand Robotaxi networks beyond the initial Texas and California launches. So while these sightings aren’t entirely unexpected, the speed of their arrival is. It suggests Tesla is confident in its ability to train FSD for local traffic rules and driving behaviors to the point it no longer needs a driver.
Bumper Cameras
The vehicle that’s been spotted in Boston is the usual Tesla engineering Model 3… except with one unique twist. It includes a front bumper camera. Shout out to @Dylan02939106 for catching the bumper camera in these photos.
The Refreshed Model 3 Mule with a Bumper Camera!

We previously released an opinion piece regarding whether the front bumper camera would be required for Unsupervised FSD. In our eyes, Tesla will require a bumper camera for Unsupervised FSD - if only to improve direct visibility in the bumper area of the vehicle. This is key for low-speed maneuvering in crowded areas like parking lots and garages, as well as for key features like Actually Smart Summon.
It isn’t surprising that Tesla is continuing to evaluate vehicles with a bumper camera - the Cybertruck, Cybercab, and Refreshed Model Y all have them now - and the rest of the lineup, including the flagship Model S and X, as well as the refreshed Model 3 - were supposed to eventually receive them as well.
With the Model S and Model X set for refreshes this year—and the front bumper camera on this Model 3 looking well-integrated rather than a temporary setup—it seems likely that front bumper cameras will soon become standard across Tesla’s entire lineup.

In fact, Tesla’s newest iteration of the FSD computer has a slot for the Bumper Camera on all AI4/HW4 vehicles, so a future retrofit could even be possible.
These are some pretty exciting times - we may see Robotaxi networks actually deploy in time for Tesla’s lofty goal of “sometime in 2026” for cities throughout North America. Once many American cities begin to accept their deployment, it will be easier to seek homologation in Mexico and Canada, enabling deployment throughout the continent.
