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 recently showed off Giga Small Haus, an interesting new display project hosted at Giga Berlin. The small new house is located just outside the main entrance of Tesla’s Giga Berlin factory, with a Quicksilver Model Y parked inside.
Giga Small Haus is powered only by solar and Powerwall 3 - disconnected from the local grid and from Giga Berlin itself. It serves as a live demonstration of Tesla Solar and Tesla’s Powerwall battery backup.
Giga Small Haus
The centerpiece of the display is a Model Y in Quicksilver - a beautiful pick for a beautifully lit house. However, that’s not the real focus here - it's the Powerwall and Gateway on the wall.
The Powerwall is the focus of Giga Small Haus, and there’s a display with some additional information on the wall. Part of the display also includes a screen that displays the current output of the Powerwall itself versus the consumption of Giga Small Haus, as well as the input from solar.
The interior exhibit of Giga Small Haus
Not a Tesla App
The text on the exhibit is divided into several sections. Here’s a translated and edited version of what we can see from Tesla’s images. Some additional text is obscured. If someone visits Giga Small Haus, let us know.
Powerwall
Powerwall is a home battery system that stores energy from solar panels, the electrical grid, or during off-peak hours and powers your home during the day or during a power outage.
With Powerwall, you can use self-generated solar energy during the day and night, thus avoiding high electricity costs. You can also store excess energy produced during sunny periods for use during times of low production or power outages.
Key Features
Energy Storage: Powerwall stores excess energy from solar panels or the grid for later use or during power outages.
Backup Power: In the event of a power outage, Powerwall automatically switches to battery power to ensure continuous power supply.
Integration: Powerwall can be seamlessly integrated with existing solar systems and other power sources.
Scalability: Multiple Powerwalls can be installed to meet higher energy storage needs.
Smart Energy Management: Powerwall works with Tesla's software to optimize energy consumption and reduce costs.
How Powerwall Works
Storage: During the day, when solar panels produce more energy than needed, the excess is stored in Powerwall.
Usage: At night or during times of low solar production, the stored energy is used to power the home, reducing reliance on the grid.
Backup: During a power outage, Powerwall automatically provides power to critical circuits, ensuring continuous operation of essential appliances.
Benefits
Cost Savings: By storing and using solar energy, you can reduce your electricity bills.
Reliability: Provides backup power during outages, ensuring your home remains powered.
Sustainability: Promotes the use of renewable energy by storing excess solar production for later use.
Overall, Giga Small Haus is an interesting real-life demo of what Powerwall and Solar can accomplish. It would be neat if Tesla built more of these displays - perhaps near major Delivery and Service Centers and at Giga Texas, Fremont, Giga Shanghai, and other facilities. Many Tesla owners have yet to learn about and experience some of Tesla’s Energy products.
Tesla has added the Acceleration Boost option to the Tesla store for owners of the 2024 Model 3 Long Range - specifically owners in Australia and China. Acceleration Boost is an upgrade that provides a significant performance boost, drastically narrowing the performance gap between the Long Range and Performance versions of the same model.
This upgrade will likely become available in Europe, Canada, and the United States in the next few days as Tesla updates its shops globally.
Acceleration Boost
This new Acceleration Boost is retailing for $3,000 AUD, or approximately $2,000 USD. That’s the same price for current owners of older Model 3 or Model Y Long Range vehicles, which all have the option to purchase Acceleration Boost through the shop.
The boost provides improved 0-100km/h (0-60mph) performance, bumping the 2024 Model 3 LR from 4.4s to 3.8s. The 2024 Performance version comes in at a blazing fast 2.9 seconds, so while it isn’t equivalent to just buying a performance variant in the first place, it is still a noticeable and significant upgrade.
Performance variants also come with a different front fascia vent for cooling, performance drive units, sport seats, adaptive suspension, 20-inch wheels, and Track Mode V3. That’s a significant number of additional features in the $10,000 USD price difference between the Long Range and Performance versions.
Should You Buy It?
If you’ve purchased a Long Range model and are itching to go just that little bit faster at every red light, this is the upgrade for you. It previously came with the cost of slightly reducing vehicle range, but the Tesla store doesn’t make a note of reduced range this time around. The 2023 Model 3 and Model Y Long Range models had an efficiency loss of about 5% due to the additional always-available acceleration and cooling.
You could drive in Chill mode to mostly negate that efficiency loss, but what’s the fun in driving in Chill when you just got Acceleration Boost? Anyhow, the shop listing for the 2024 variant doesn’t include this detail, so it's possible Tesla may have worked some more engineering magic.
Overall, if you’ve got the $3,000 AUD burning a hole in your pocket, some Tesla referral credits sitting around, or just want to go faster, it's definitely an upgrade many users find valuable.
