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.

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 is holding its 2025 Q1 earnings call today at 2:30 pm PT / 5:30 pm ET / 9:30 pm UTC. The earnings call will be followed by a Q&A session with Tesla executives, including Elon Musk.
We expect the focus to be on Tesla sales for the quarter, FSD Unsupservised and the Robotaxi network. Tesla may also discuss its upcoming, more affordable model, Optimus, and other products.
Listen Live
The event will be live-streamed on Tesla’s site. It is also expected to be streamed on X and YouTube like it has been in the past. Tesla has changed this from an Earnings Call to a Company Update, but it’s unclear whether the phrase change holds any significance in what will be shared.
Update: You can listen to Tesla’s earnings call live below. If you prefer, you can also listen live on Tesla’s website.
Start Time
Tesla's live stream starts at 2:30 pm PT, which is the following times around the world:
2:30 pm Pacific Time
5:30 pm Eastern Time
10:30 pm UTC
10:30 pm - London, England
11:30 pm - Berlin, Germany
9:30 am (April 23rd) - Sydney, Australia
Q&A Questions
The questions asked during the Q&A portion of the call come directly from investors. These are currently the top-voted questions, so we’ll likely see answers to several of these questions:
What are the highest risk items on the critical path to robotaxi launch and scaling?
When will FSD unsupervised be available for personal use on personally-owned cars?
Is Tesla still on track for releasing “more affordable models” this year? Or will you be focusing on simplified versions to enhance affordability, similar to the RWD Cybertruck?
Does Tesla see robotaxi as a winner-take-most market, and as you approach the Austin launch, how do you expect to compare against Waymo’s offering, especially regarding pricing, geofencing and regulatory flexibility?
Can you please provide an update on the unboxed method and how that is progressing?
How is Tesla positioning itself to flexibly adapt to global economic risks in the form of tariffs, political biases, etc.?
Does Tesla still have a battery supply constraint (noted on Q4 ER call) and how does this change w/tariffs?
Did Tesla experience any meaningful changes in order inflow rate in Q1 relating to all of the rumors of “brand damage”?
Regarding the Tesla Optimus pilot line, could you confirm if it is currently operational? If so, what is the current production rate of Optimus bots per week? Additionally, how might the recent tariffs impact the scalability of this production line moving forward?
Robotaxi still on track for this year?’
Look Back at 2025 Q1 Numbers
Most of Tesla’s Q1 deliveries, 323,800 units, were unsurprisingly for the Model 3 and Model Y, while the “Other Models” category (including the Cybertruck, Model S, and Model X) accounted for 12,881 deliveries.
Comparing these numbers to Q1 2024, the Model 3/Y is down about 13%, while the Model S/X and Cybertruck are down about 24%.
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 stated that the ramp is “going well.” However, deliveries and production were both down year over year.

Although Tesla doesn’t officially break down its numbers by region, Troy Teslike, who closely monitors Tesla's delivery and production numbers has provided estimates that show Tesla’s deliveries across regions. Tesla delivered the most vehicles in China this past quarter, so it’ll be interesting to see if this trend continues.
His estimates for the regional break down are below:
Tesla’s Giga Texas factory usually gives us the first site of Tesla’s upcoming products. We first saw the Cybertruck and Model Y castings here. With Giga Texas being one of Tesla’s largest factories, it’s logical that most products would originate here.
Tesla has also stated that it intends to manufacture the Cybercab, Semi, the next-generation vehicle, and Optimus at Giga Texas over the coming years. The affordable vehicle and Cybercab were originally intended to be manufactured at Giga Mexico, but the plans for that facility were waylaid by changes in economic policy.
Robotaxi Castings
These new castings were spotted by Joe Tegtmeyer, who regularly does drone flights of Giga Texas. Joe pointed out that these castings don’t look like the usual Model Y or Cybertruck castings usually seen outside Giga Texas.
With an eagle eye, @minusYCore on X also spotted some interesting text on the frames holding the castings up. In particular, the castings say “RTTX050” and “W68-RSF AS-CAST”. These could be interpreted as ‘Robotaxi Texas’ and ‘Rear SubFrame,’ as Tesla marks Cybertruck castings as “CTTX.” The as-cast portion indicates that these particular castings haven’t been trimmed yet, according to the X user.
The castings laid out.
@JoeTegtmeyer
The size and shape of these castings—combined with rumors that Tesla’s more affordable vehicle has been delayed—suggest that these castings are intended for the Cybercab.
These castings are much flatter and appear to be a different size than the castings found throughout Giga Texas, indicating that they are intended for an entirely different product.
It’s possible that these are the first castings used by Tesla to test their unboxed assembly process, which the Cybercab is expected to rely on. If you take a closer look at the video below, you’ll note that these new castings look very similar to the ones in the unboxed assembly video.
Interestingly, Tesla did say that they don’t intend to have the Cybercab available for customers before late 2026 or early 2027, but we’ll likely hear updated timelines as Tesla’s Q1 2025 Earnings Call tomorrow.
A more vertical look at the castings.
@JoeTegtmeyer
New Giga Presses
To top it all off, new parts for a Giga Press - the machine Tesla uses to make these castings - were also sighted in Texas. These machines are few and far between, and each one is highly specialized for the particular vehicle it produces. Seeing new parts coming in usually indicates that a new assembly line is under construction, or that changes are being made to an existing line to either expand it or update it.
There’s a lot happening and we will hopefully know more tomorrow evening.
