Rendering of what Tesla's new 'Drive on Sunshine' feature may look like
Not a Tesla App
Tesla is getting ready to introduce a new feature that allows owners to charge their cars using surplus solar energy. If your home is generating more energy than it's using, this excess energy can be directed automatically to your car.
For owners of solar panels, there have been limited options when your panels are generating more energy than you're using. The system tops off your Powerwalls if you have them, but once those are full, the system sends any excess energy back to the grid.
However, if you have a Tesla, you'll soon be able to automatically start charging your vehicle whenever excess energy is being generated. This is according to new text-based information found in the latest Tesla app, according to Twitter user Tesla App iOS. Tesla is calling this new feature "Drive on Sunshine," which focuses on providing the cleanest charge possible for Tesla vehicles.
Tesla has already started updating their app with some details regarding this new feature. The feature will instruct users to plug in at home during daytime hours, to take advantage of the surplus clean energy their solar system produces.
How It Will Work
The Tesla app allows you to set a charging limit for your vehicle. However, once this new feature is enabled, you'll gain access to two charging sliders. The first slider will control how much your vehicle is charged, regardless of where the energy is coming from. You'll be guaranteed to have this amount of charge every night. However, you'll have access to a new slider that lets you set the maximum charge level, but only using your solar system's clean energy.
This will allow you to set your charging limit to a minimum amount every day, such as 60%. You could then set your solar limit to something much higher, such as 90%. This will allow your vehicle will charge up to this limit when your solar system is producing excess energy.
By setting charge limits and specifying the desired charging times and locations, Tesla owners can ensure that their vehicles are being fully charged before excess energy is sent to the grid.
Apple Inspired?
Last September, we pondered if Tesla could develop something similar to Apple's Clean Energy Charging. Apple optimized iPhone charging times by prioritizing clean energy sources from the grid. This approach aligns with Tesla's mission to create zero-emission vehicles that can charge using clean, renewable energy.
The app also lets users charge their vehicle's battery using available energy sources for regular daily driving needs while reserving a portion of the battery to be charged exclusively when surplus solar energy is available.
Explains Recent Powerwall Announcement
This new functionality enables Tesla owners to charge their cars using renewable solar energy, reducing the reliance on fossil fuels throughout the charging and driving experience.
Tesla's goal is to make EV ownership as sustainable as possible by minimizing the use of fossil fuels and promoting clean charging options. When a household generates more solar energy than it can consume, this excess power can be directed toward charging the vehicle. Tesla again began offering the Powerwall as a standalone product, allowing customers to purchase the battery storage system without requiring a solar array.
The Drive on Sunshine feature is a major step forward in Tesla's mission to make electric vehicle ownership as sustainable and environmentally friendly as possible. With this update, Tesla continues demonstrating its commitment to creating a cleaner, greener future for all.

Just over a week into the Robotaxi launch, Tesla began laying the groundwork for a more scalable remote supervision model, which will be key to achieving success with the Robotaxi Network.
About a week ago, Elon Musk posted on X that Tesla will likely reach the crucial safety threshold to enable this shift within a month or two. While that means at least another month of in-vehicle Safety Monitors, it does provide us with a timeline of what to expect.
As soon as we feel it is safe to do so.
Probably within a month or two. We continue to improve the Tesla AI with each mile driven.
This timeline came in response to a question about Tesla’s plans for the ratio of autonomous vehicles to remote supervisors. The more vehicles that a single human can supervise, the better, especially if that number can be reduced to something drastic, like a 100:1 ratio. A single human operator would be able to manage an entire city of Robotaxis, which will be critical to make the Robotaxi Network turn a profit.
While Tesla works towards that ambitious future, it is also taking immediate steps to improve the current user experience during the Austin pilot program, where 15-minute wait times have become the norm.
Solving for Wait Times
According to Eric E, one of Tesla’s principal engineers on Robotaxi, the current 15-minute wait times are a classic logistics challenge. The supply of vehicles is lower than the current demand for rides. To solve this, there’s a two-pronged solution for Tesla.
First, Tesla is directly increasing supply by hiring more Safety Monitors/Vehicle Operators in Austin, even hosting an on-site hiring event.
We're looking to hire more Vehicle Operators in Austin, TX to accelerate Robotaxi deployment. We will be hosting an onsite hiring event next Thursday. Please consider applying to the official job posting and completing this hiring event form:
Second, Tesla is working to make FSD and the Robotaxi fleet management software faster and smarter. This means they are utilizing the data from the pilot to better orchestrate the fleet by predicting demand and pre-positioning vehicles in prime locations to reduce wait times. After dropping someone off, the vehicle can start traveling to areas of higher demand, even if someone hasn’t booked a ride yet.
Next Up: Remote Supervision
These immediate fixes are all in service of that much larger goal. Scaling the Robotaxi Network isn’t just about having more cars; it’s about increasing the number of vehicles a single human can safely supervise remotely, which is a requirement for Robotaxi to turn a profit.
Elon’s comments give us this timeline. A more flexible and favorable ratio of 3:1 (although still far from the ideal 100:1) is likely to be achieved within a few months.
Tesla is committed to safety, as evidenced by the safety monitors in the vehicle. A single incident could not only tarnish the public’s view of the Robotaxi Network but could also halt Tesla’s operations altogether.
The data gathered from more Robotaxis on the road is crucial to the whole project. Tesla is gathering more data and issuing newer FSD builds specific to the Robotaxi.
As FSD requires less remote oversight per mile driven autonomously, Tesla can safely increase the number of vehicles per remote supervisor, moving the service closer to its ultimate goal.
Tesla has laid out an aggressive roadmap for the Robotaxi Network and its next few phases. We’ll have to wait and see just how this goes over the next few months, and whether they feel comfortable enough to increase the geo-fence and remove safety monitors.
Following the recent news of Grok being almost ready for Tesla vehicles, Elon Musk confirmed on X that the next major step is with Optimus, Tesla’s humanoid Robot. xAI’s advanced Grok models will eventually serve as the voice and brain for Optimus. This will be a convergence of Musk’s two biggest AI ventures — Tesla and xAI.
This will combine a physically humanoid robot - the brawn - with the new brains, Grok. This integration is more than just giving Optimus a voice - it suggests that Tesla is thinking ahead and possibly intends to use Grok to understand the environment around Optimus, while FSD will handle the robot’s movements.
The combination of Optimus and Grok creates a relationship where each component plays to its strengths.
For years, Tesla’s robotics team has been focused on the immense challenge of physical autonomy. Optimus learns complex tasks by observing humans, basically training itself through video by watching humans. This helps Optimus develop the physical dexterity needed to work in the real world. This is the brawn - the ability to navigate, manipulate objects, and perform useful work.
Grok provides the conversational brain. It adds a layer of natural language understanding, reasoning, and interaction. Instead of needing a computer, a specialized app, or pre-programming commands to give Optimus instructions, a user will be able to simply talk to it in a natural way. This makes Optimus infinitely more approachable and useful, especially for tasks in a dynamic environment, such as work or at home.
xAI and Tesla
Viewed from a different perspective, this move isn’t just about upgrading one product. It is the clearest evidence that xAI and Tesla are collaborating together to build a single, unified AI platform. Musk’s biographer, Walter Isaacson, believes Tesla and xAI will merge. Seeing Tesla and xAI both play critical roles in creating Optimus makes us believe that it may very well be the case.
Transformation to a Humanoid Robot
The confirmation of Grok in Optimus is one of the most significant milestones for the project to date. While Optimus’s ability to walk and work (and dance) is already an incredible engineering feat, it has all been physical abilities so far. Adding the ability to interact with Optimus in a human-like way will transform Grok from a machine to a true, general-purpose humanoid robot.
The ability to understand nuanced requests, ask clarifying questions, and respond intelligently is what will ultimately make Optimus a daily fixture in our lives.
