Nomad Notes #9: Update Solar Array Calculations, Cybertruck Decisions,and More!
Hello, HV Nomads community!
We're excited to share some major progress on our sustainable travel project. In this update, we'll delve into our solar array design, the exciting potential of the Cybertruck, and some creative solutions we've found along the way. Get ready for detailed insights into our solar setup, the pros and cons of switching to a Cybertruck, and how we're tackling challenges like license plate mounting. Our trailer plate came in but it’s motorcycle-sized, and the mount on the vehicle is full-sized. Let's dive in!
A Bright Idea: Upgrading to a Four-Layer Solar Array
After careful consideration, we've decided to upgrade our solar array setup to a four-layer design using powerful 560-watt bifacial panels. Initially, we planned for short, stubby wings covering the main panels, sliding out from the center. However as we explored different panel options, we realized that keeping the wings aligned with the trailer's length would cause them to overhang the roof like a top hat's brim.
By maximizing our solar potential and maintaining a sleek look, we've settled on a design that not only looks fantastic but also significantly increases our energy production. This new setup is a game-changer, allowing us to charge our Tesla Model X in one to four days while camped during summer in the Southern states. We're confident that this upgrade will bring us closer to our goal of sustainable travel.

Awnings and Support System
Our solar ambitions didn't stop there. We've also added a rear awning array, creating a truly comprehensive solar power system. Initially, we thought we'd need custom fabrication and support poles for the awning, but thanks to the lighter weight of the panels, we were able to utilize commercially available industrial drawer slides to support the arrays. This not only simplifies the build but also eliminates the need for extra poles, saving us fabrication time and money.
Battery Backup and Cybertruck Considerations
To ensure a reliable power supply, we've chosen a robust battery setup capable of handling multiple cloudy days. We're still finalizing the exact appliance and lighting needs, as well as exploring the potential use of the Cybertruck's Powershare feature to complement the system, potentially reducing the number of battery modules needed.
Speaking of the Cybertruck, we're still weighing the pros and cons of potentially upgrading from our Model X. While the Cybertruck offers more range, power export capabilities, and a head-turning design, the towing range improvement is minimal compared to our current setup with free Supercharging. According to YouTube demos, we're talking about a mere 10 to 20 miles of additional range for a $100,000 investment by moving up to the Cybertruck before the Range Extender is available.
The truck does offer three significant benefits to our project:
The ability to carry full water tanks.
The power share option.
Its head-turning design will attract more eyeballs and attention to our project.
Additionally, the Cybertruck is much more nimble than our six-year-old Model X, thanks to its four-wheel steering and smaller turning circle, which will make parking the rig easier.
We really want the truck, but we also like eating. If I've miscalculated or Tesla ships it early, those car payments might impact our ability to complete the build. We could end up with a trailer and two cars that can't go anywhere.
If I can secure a sponsorship deal where they want us to have the visibility of the Cybertruck right now, we'll open our email from Tesla and convert our reservation to a Foundation Series order. When I checked a few days ago, Tesla was saying July to August was the estimated delivery time for all the options I picked. If we find some unexpected money, like winning one of those record-setting lotteries with a one-dollar ticket, an inheritance from a long-lost relative in Nigeria, or getting a great offer on our house (the only realistic option here 😅), we might also do it. In reality, we'll likely be ordering sometime after the non-Foundation Series becomes an option, and we'll still want the range extender. This will give us enough range to comfortably point at a place on the map without range anxiety, as we've become accustomed to doing with the Model X and the extensive and continually growing Supercharger network. We only make sure we're at 80% or above before punching in a destination and just rolling when not towing.
We're eager to hear your thoughts on our progress and the choices we're facing. Do you have any experience with similar solar setups or advice on the Cybertruck vs. Model X debate?
