Tesla is set to introduce its innovative "Drive on Sunshine" feature, which allows Tesla owners to charge their cars using surplus solar energy generated by their home solar panels. We first revealed the feature in March with a rendering of what the feature could look like based on details found in the app.

However, we now have our first official screenshots shared by Twitter user @olympusdev_. If you have Tesla Solar and possibly a Powerwall, the feature promises to bring more efficiency and economy to Tesla's clean energy efforts.

For solar panel owners, options for utilizing excess energy generated have been limited. Typically, the surplus energy charges Powerwalls if available, and once full, the excess is sent back to the grid. However, Tesla's "Drive on Sunshine" feature aims to provide a better solution for using this excess energy, making it more economical for Tesla owners than selling the energy back to the power company.

According to a phrase found by Olympus, the "Drive on Sunshine" feature may require a Powerwall to function, although it's not entirely clear. The phrase "Charge on Solar paused for Powerwall Export" hints at the integration of Tesla's energy storage system with the new feature. Further details regarding the exact role of the Powerwall in this process are yet to be disclosed.

How "Drive on Sunshine" Works

The Tesla app, which already allows users to set charging limits for their vehicles, will gain new functionality with the "Drive on Sunshine" feature. Users will have access to two sliders, one for setting the minimum charge of the vehicle that they'd like regardless of the energy generation source and another, called the "Charge on Solar" slider, for specifying the maximum charge they'd like from excess solar energy.

For instance, Tesla owners can set a minimum charge level for daily driving, such as 50%, and a solar limit of 90%. The car will charge at the time specified to reach your minimum charge goal of 50%, enough for your daily errands. If the vehicle remains plugged in during the day and excess solar energy is available, the car will automatically charge up to the 90% limit.

Charging from Multiple Solar Sites

Another exciting aspect of the "Drive on Sunshine" feature is the ability for Tesla owners to choose from multiple solar sites where they want their vehicles to charge using excess solar energy. This added flexibility allows owners to optimize their vehicle charging based on the availability of surplus solar power in different locations.

Release Date

It appears that the Drive on Sunshine feature is dev complete or nearing completion, based on the underlying source code in the latest Tesla app. It may even already be live and in testing for some employees. The feature is expected to launch soon for the general public, and it may even not require an app update for it to appear. Tesla may simply be able to adjust a configuration to turn this feature on for everyone. Keep an eye out for it in your Tesla app.

Tesla's "Drive on Sunshine" feature marks a significant step forward in using clean energy for electric vehicle owners. By enabling Tesla owners to charge their vehicles using excess solar power, the feature ensures a more efficient and eco-friendly approach to electric vehicle charging.

As Tesla continues to push the boundaries of clean energy and electric vehicle technology, the "Drive on Sunshine" feature is yet another example of its commitment to creating a sustainable future.

Tesla Vehicles Spotted With LiDAR: What Do They Use It For?

Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.

However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.

What is LiDAR?

LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.

Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.

While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.

Why Does Tesla Use LiDAR?

At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.

Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.

Tesla’s vision-only system has been seen to be extremely accurate, with Vision-only Autopark being able to park in even narrower and tighter spaces faster than the previous version that relied on ultrasonic sensors.

We’ll likely continue to see Tesla purchase LiDAR systems, as well as use them for validation well into the future.

Tesla's Upcoming Robotaxi Event in August Delayed, According to Bloomberg

In a report from Bloomberg, it is claimed that Tesla will be delaying its much-anticipated 8/8 Robotaxi event by two months to October 2024.

While sources other than Bloomberg haven't confirmed this report, Bloomberg has a positive track record of reporting on financial decisions. We’ll be sure to update the article if there is confirmation on X from Elon Musk or another Tesla senior official.

Tesla’s stock has dropped nearly 8.5% over the day, ending back-to-back gains over the last two weeks. It closed yesterday at $ 241 after hitting a peak of $270 earlier in the day before the news broke.

Why the Delay?

The delay – of approximately two months – has been communicated internally, but not publicly announced just yet. Bloomberg goes on to mention that the design team was told to rework certain elements of the Cybercab, necessitating the delay.

If Bloomberg’s report is correct, it sounds like Tesla’s unveil event will be largely focused on showing off the vehicle, instead of demoing how it will work. Of course, it could still be both, but given past events, Tesla has always shown off the vehicle years before it hits production.

Rimac recently showed off their version of robotaxi vehicle named Verne, and surprisingly, it could almost pass for Tesla’s own robotaxi. A lot of design cues in Rimac’s version are elements we have already seen or expect to see in Tesla’s autonomous taxi.

A recent Tesla patent revealed that Tesla is incorporating a sanitation system into their robotaxi that will be responsible for analyzing and cleaning the vehicle’s interior, although the delay itself is likely tied more to a physical feature rather than software.

Another element we know almost nothing about is how Tesla plans to charge these robotic taxis. Will they rely on the existing charge port and adapt a solution like the robotic charging arm (video below) we saw almost eight years ago, or will wireless charging or a dock finally become realized?

While the delay for Tesla’s event appears to be related to the vehicle’s design itself and not further development of FSD, Tesla is wasting no time in getting FSD working for the upcoming vehicle. Model 3 vehicles have already been spotted with camera locations that resemble a robotaxi.

Is the Delay Accurate?

We expect that this delay might actually be true – Elon Musk usually takes to X within hours of such news breaking if it's false to refute it and hasn’t done so yet.

Tesla has delayed several of their events in the past, and a delay of a couple of months seems plausible. We should hear from Musk himself soon on whether this report is accurate.
