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.

It was a rainy April 1st when a news-searching author went on a delve into the depths of April Fools to find fact from falsehood. And while we found a lot of fantastic jokes, we also found some good ideas.
So, with a shoutout to MarcoRP on X, whose April Fool’s Joke gave us a good run for our money for a couple of minutes, we thought to ourselves - what would a Cybercab Charging Station / Cleaning Hub really look like?
Cybercab Wireless Charging Sites
Now, before continuing, we’d like to point out that the image up top is a joke from Marco - it isn’t an accurate or real site map submission from Tesla. However, it gave us the impetus to think critically about what is required for a Robotaxi fleet, based primarily on the Cybercab, to be able to service a city.
Requirements
Tesla will likely need to charge a small fleet of Cybercabs at a single time and in a single place. That means that the site needs to be large enough to cover a major metro area while also still being compact enough to not cost too much money to build out.
In addition, we need to factor in charge times. The Cybercab is likely to launch with a battery around 50 kWh, which will result in a range of approximately 300 miles. With that much range, the average Cybercab may not need to charge more than once or at all during daytime shifts, so instead, most of the vehicles will charge overnight.

Math and Charge Times
The overnight charging means that most of these vehicles could be charged slowly. When we did some back-of-the-napkin math last year, we determined that Tesla’s wireless charger will likely peak around 17 kW (for comparison, Tesla’s Wall Connector at 32 amps charges at about 7 kW). If we scale Tesla’s wireless charger down slightly to 10 kW, accounting for some energy loss and the potential size of the site, that means a Cybercab will be able to charge in about 5 hours.
Tesla’s upcoming V4 Supercharger unit can currently handle 1.5MW per cabinet, but this slower-speed charging is A/C, not DC, which means there is a step-down loss of about 3-5%. Let’s make that a comfortable 10% for any other overages, but we can estimate around 1.35MW of power. That 1.3MW will easily handle charging up to 100 Cybercabs at once - all wirelessly, using Tesla’s unique beam-forming and beam-steering technology to keep efficiency high at every single stall.
Within about 5 hours, a whole fleet of 100 Cybercabs could be charged overnight when electricity rates are cheaper and still be out in time for the morning commute.
While this is all just hypothetical, it really does make sense that Tesla will be establishing these sites that won’t require much space or a ton of energy.
Tesla recently curtained off a large section of the parking garage at Giga Texas, as well as some of their chargers on the eastern end of the facility, leading us to believe they may just be testing this at scale internally.
There’s a lot to look forward to with Tesla’s V4 Supercharger deployment coming this year and with Robotaxi launching in just a couple of months.
Tesla released its Q1 2025 delivery and production numbers this morning, reporting 336,681 vehicles delivered and 362,615 produced—marking the company’s weakest quarter since 2022. Deliveries declined 13% year-over-year and fell well short of Wall Street estimates, which ranged from 360,000 to 370,000. Some analysts had forecast as many as 407,000 units.
Despite the shortfall, Tesla stock is actually up about 4% this morning, not only suggesting the market had already priced in weaker performance, but that this may be seen as the low point for the company. Tesla began delivering its refreshed Model Y in March, and production across all four Gigafactories was impacted by several weeks of downtime as Tesla retooled lines to accommodate the newer model. However, there’s no doubt that there is some brand impact from Elon Musk.
Comparing Numbers
Most of the deliveries—323,800 units—came from the Model 3 and Model Y lineup, while the “Other Models” category (including the Cybertruck, Model S, and Model X) accounted for 12,881 deliveries. That’s a 31% drop for Model 3/Y and a sharper 45% drop for the Other Models category compared to the previous quarter. However, comparing it to a more applicable Q1 2024, these numbers are only down about 13% for the Model 3/Y and down about 24% for the Model S/X and Cybertruck.
In terms of production, Tesla built 345,454 Model 3/Y vehicles and 17,161 from its “Other Models” line. The company attributed the production drop to the Model Y changeover but said the ramp is “going well.” This still leaves a large gap between production and delivery numbers, although they may not be as large as many had feared.

Cybertruck
One major weak point in Tesla’s numbers seems to be Cybertruck deliveries. While Tesla previously expected the Cybertruck to sell more than 250k units per year, we’re already seeing a decline in numbers. This is likely due to several factors, including the higher-than-expected price point of the truck, the unavailability of the RWD model, and the Cybertruck’s polarizing design, which may attract unwanted attention right now.
While the Cybertruck was ramping up production in 2024, making the lower numbers reasonable, the deliveries for Q1 2025 dropped drastically compared to the previous quarter. Cybertruck deliveries are estimated to be in the 5- 6k unit range for the quarter.
The good news to take away here is that the Single Motor variant of the Cybertruck appears to be nearing release. The price of the RWD version is expected to be about $60k USD before any incentives.
Q1 Earnings Call
Tesla announced their quarterly numbers this morning and posted on social media that they’ll live stream their Earnings Call on April 22nd.
This post was later edited to change “Q1 Earnings Call” to “Q1 Company Update.” It’s not clear whether there’s any significance in this change, but it could mean that Tesla has more to announce during the call.
The Company Update will occur on April 22nd at 2:30 PM PT / 5:30 PM ET. The standard Q&A session with executives and Musk is expected to follow the release of additional financial results for the quarter.
Tesla is set to launch its long-awaited Robotaxi service in June, and a cheaper, mass-market model is also planned for this year. With delivery numbers coming in soft and the refreshed Model Y just hitting the road, all eyes will be on forward-looking commentary during the update.
