Integrating Portable Solar Panel Technology into the Tesla Model S
******************
UPDATE: 8/19/14 – After three months of continuous everyday use, both in-car and outdoors (predominantly left on the patio), the Voltaic 10W portable solar system has managed to power a household of two iPhones and one iPad purely on solar energy, and become a welcomed new member of the family.
It took some getting used to at first considering the entire assembly is as tall as a high schoolers backpack and more cumbersome to lug around than some of the smaller portable solar devices that I had a chance to test (Solar Joos, Anker). But despite the larger size, the Voltaic solar panel was hands down the best performing, most reliable and had superior quality over the others. In fact, it’s changed my entire perspective on how useful solar energy can actually be to the point I felt dirty just plugging anything into a wall (as ironic as that may sound from an EV family).
The Voltaic System portable solar panel device is certainly not the cheapest and some will argue that the cost for portability far exceeds what you would be paying if using a standard wall outlet, and they are right.
But for some it goes beyond just a cost benefit analysis. If you’re that type, then this device is for you. All in all, it’s a superb device in every sense and has made me become quite reliant on it. It’s hard to imagine adjusting back to using outlets for my mobile and tablet devices when each day brings free energy from the sun.
Read the original review below.
******************
Elon Musk has long touted that solar energy will be the future of electric vehicles so why wasn’t it incorporated into the Tesla Model S?
A part of me still wonders why this never happened. Perhaps it was a way to offset the large costs associated with having an automotive-grade lithium ion battery pack capable of 260+ miles of range. Or was it due to the fact that roof-integrated solar cells à la now defunct Fisker is nothing more than a cool factor with no real cost benefit?
Either way, it got me thinking – how can I store some of the sun’s energy while embarking on a long distance Tesla road trip? Or better yet, store solar energy while the Model S is at rest during the work week? The energy recouped through the sun need not be channeled back into the car itself, but could still provide usable power for a mobile device or laptop.
This exact thought led us to find three leading makers of portable solar charging technology with the goal of being able to store solar energy implicitly through our Tesla Model S. We’ll be conducting a review of each product in a three part series. The first being Voltaic System‘s Fuse 10W Solar Laptop Charger.
Initial Impressions
Voltaic’s 10W Fuse Solar Charger dominates in its presence. The three large solar panels encased within a beautiful gloss coated metal frame is a tell-tale indicator that this device can pack some serious charging capabilities. At first I was surprised to feel how heavy the entire unit was (3.6 lbs), only to later find out that the bulk of the weight was from the detachable high capacity lithium polymer battery that was stowed inside the zippered clam-shell casing.
Attached to the back of the Fuse Solar Charger unit was a set of straps and clips which, frankly, I had no idea how to use but was eager to learn.
Technical Specifications
The Fuse is capable of generating 10 Watts of power through its three 3.4 Watt solar panels. Configurable voltage settings provide the flexibility to power your most basic low voltage mobile device and tablets, to laptops and digital cameras that can demand up to 18V.
Aside from the obvious good of using renewable solar energy, Voltaic Systems took it to a whole new level of being eco-conscious by mounting the solar panels to a durable and lightweight shell made from recycled plastic soda bottles, otherwise known as PET. The clam shell design allows it to be used as a storage container for the detachable 20,000 mAh, 72 Wh lithium polymer battery and a plethora of device adapters.
NOTE: Amazon’s description shows a 16,000 mAh although the one we received directly from Voltaic Systems contained a 20,000 mAh battery
Tablets and small notebooks can easily fit within the casing.
LEDs on the battery indicate the level of charge. Five lit LEDs represents a full 100% state of charge. The battery has a USB out as well as an attachment set that allows you to connect to virtually any type of device.
Solar Panels
- Solar panels are waterproof and abrasion resistant
- Power: 10 Watts total peak output at 6 or 18 Volts
V72 Universal Laptop Battery
- 20,000 mAh, 72 Wh battery capacity is one of the larger portable batteries I’ve seen. Capable of replenishing an iPhone ten times and an iPad twice on a single charge.
- When not in the sun, the battery can also be charged through the included DC car or AC chargers, making it just as useful on the grid as off.
- Charge Time: In direct sun, V72 battery fully charges in 14.5 hours from 10 Watts and in 9 hours from 16.8 Watts of solar panels.
- Protection: Short Circuit, Over Charge, Over Discharge, Over Current, Over Temperature
- Charge Display: LEDs light sequentially when charging.
- Capacity Display: 1 light < 20%, 2 lights < 40%, 3 lights < 60%, 4 lights < 80% full, 5 lights > 95%
Solar Charging Tesla Center Console
Instead I found a perfect home for the Fuse in the Tesla Model S center channel. Not only does it fit great within that location, it helped conceal any miscellaneous belongings that would normally be left out in the open without a Tesla Center Console unit.
Charging in direct sunlight will clearly achieve the best charging results, but nevertheless I wanted to see how much solar energy I can gather behind the UV protected glass of the Model S.
A red LED towards the top of the “Voltaic” insignia lights up as soon I placed the Fuse solar charger between the two front seats to indicate that solar energy is being collected. Bingo.
Placing the Fuse 10W Portable Solar Charger on the Model S center channel allows it to harnesses the power of the sun and store it for later use.
Even behind glass I was able to capture enough solar energy to charge a mobile phone. However, the most common use case for me was to leave the Fuse in the center channel of the Model S each day while I was at work. It’s always an exhilarating feeling to be able to come back to some additional energy at the end of each work day. The energy is stored within the detachable battery making it a useful battery extender for my notebook when I’m on the go or just as a battery backup.
Summary
Voltaic System’s Fuse 10W Portable Laptop Charger is extremely durable and capable of the most rugged of outdoor adventures. Short of going on a camping excursion where access to electricity maybe limited, it’s hard to see the need to carry both laptop and Fuse device simultaneously, although the name of the product may suggest otherwise.
However if you’re looking for a world-class portable solar charging device that can mount to practically anything, blends naturally into the Tesla Model S, has a huge industry-leading 20,000 mAh battery capacity with adjustable voltage outputs, and don’t mind paying a premium $339 USD, then Voltaic System‘s portable solar charger just might be for you.

Trump’s invite for Elon just reshuffled Tesla’s big Signature Delivery Event
Tesla rescheduled its final Model S farewell to May 20 after Musk joined Trump in China.
Tesla has rescheduled its Model S and Model X Signature Edition delivery event to Wednesday, May 20, 2026, after abruptly calling off the original May 12 celebration. The event will take place at Tesla’s factory at 45500 Fremont Boulevard in Fremont, California, the same location where the Model S first rolled off the line in 2012. Invitees received a follow-up email asking them to reconfirm attendance and download a new QR code ticket, with Tesla noting that all travel and accommodation expenses remain the buyer’s responsibility.
The reason behind the original cancellation came into focus the same day it was announced. President Trump invited Elon Musk, Apple’s Tim Cook, BlackRock’s Larry Fink, Boeing’s Kelly Ortberg, and executives from Goldman Sachs, Blackstone, Citigroup, and Meta to join his trip to China this week for a summit with President Xi Jinping. The agenda covers trade, artificial intelligence, export controls, Taiwan, and the Iran war, following weeks of escalating friction between Washington and Beijing over AI technology, sanctions, and rare earth exports. Trump wrote on Truth Social, “I am very much looking forward to my trip to China, an amazing Country, with a Leader, President Xi, respected by all.”
Tesla launches 200mph Model S “Gold” Signature in invite-only purchase
The vehicles at the center of all this are the last Model S and Model X units Tesla will ever build. Priced at $159,420 each, the 250 Model S and 100 Model X Signature Edition units come finished in Garnet Red with a one-year no-resale agreement, giving Tesla right of first refusal if the owner decides to sell. As Teslarati reported, the Model S defined Tesla’s early identity as a serious luxury automaker, and the Fremont factory line that built it is now being converted to manufacture Optimus humanoid robots.
Musk’s inclusion in the China delegation drew attention given his very public relationship with Trump, and the invitation signals the two have moved past and past grievances. Trump originally brought Musk on to lead the Department of Government Efficiency following his inauguration, and despite a sharp public dispute in mid-2025, the two have appeared together repeatedly in recent months. A seat on the China trip, the most diplomatically consequential visit of Trump’s current term, puts Musk back at the table on U.S. economic policy at a moment when Tesla’s China revenue remains one of the company’s most important financial pillars.

Tesla Semi hauls fresh Cybercab batch as Robotaxi era takes hold
A Tesla Semi was filmed hauling Cybercab units out of Giga Texas for the first time.
A Tesla Semi loaded with Cybercab units was recently filmed leaving Gigafactory Texas, marking what appears to be the first documented delivery run of Tesla’s autonomous two-seater. The footage shows multiple Cybercabs secured on a flatbed trailer being hauled by a production Tesla Semi, a truck rated for a gross combination weight of 82,000 lbs. The location is consistent with Giga Texas in Austin, where Cybercab production has been ramping since February 2026.
The sighting follows a wave of Cybercab activity at the Austin facility. In late April, drone operator Joe Tegtmeyer spotted approximately 60 Cybercabs parked in two organized groups in the factory’s outbound lot, the largest concentration observed to date. Units being staged in an outbound lot is a standard pre-delivery step, and the Semi footage is the logical next frame in that sequence.

This is not the first time Tesla has used its own Semi to move Tesla products. When the Semi was unveiled in 2017, Musk noted it would be used for Tesla’s own operations, and over the years Semi prototypes were spotted carrying cargo ranging from concrete weights to Tesla vehicles being delivered to consumers. In 2023, a Semi was photographed transporting a Cybertruck on a trailer ahead of that vehicle’s delivery launch.
The Cybercab itself was first revealed publicly at Tesla’s “We, Robot” event on October 10, 2024, at Warner Bros. Studios in Burbank, where 20 pre-production units gave attendees rides around the studio lot. Musk stated at the event that Tesla intends to produce the Cybercab before 2027. The first production unit rolled off the Giga Texas line on February 17, 2026, with Musk posting on X: “Congratulations to the Tesla team on making the first production Cybercab.”
Tesla’s annual production goal is 2 million Cybercabs per year once multiple factories reach full design capacity, with the company targeting a price under $30,000 per unit. Tesla has confirmed plans to expand its robotaxi service to seven cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, building on the unsupervised service already running in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year.

Tesla owners keep coming back for more
Tesla has taken home the “Overall Loyalty to Make” award from S&P Global Mobility for the fourth consecutive year, reinforcing Tesla owners’ willingness to come back. The 2025 awards are based on S&P Global Mobility’s analysis of 13.6 million new retail vehicle registrations in the U.S. from October 2024 through September 2025. The complete list of 2025 winners includes General Motors for Overall Loyalty to Manufacturer, Tesla for Overall Loyalty to Make, Chevrolet Equinox for Overall Loyalty to Model, Mini for Most Improved Make Loyalty, Subaru for Overall Loyalty to Dealer, and Tesla again for both Ethnic Market Loyalty to Make and Highest Conquest Percentage.
Tesla’s streak in this category started in 2022, and the brand has now won the Highest Conquest Percentage award for six straight years, meaning it keeps pulling buyers away from other brands at a rate no competitor has matched. Tesla’s retention among Asian households reached 63.6% and among Hispanic households 61.9%, rates that significantly outpace national averages for those groups. That breadth of appeal across demographics adds a layer of significance to a win that some might dismiss as routine.
The timing matters too. After several consecutive quarters of decline, Tesla’s share of U.S. EV sales jumped to 59% in Q4 2025. That rebound, arriving just as competitors were flooding the market with new models and incentives, suggests Tesla’s loyalty numbers are not simply the result of limited alternatives. Buyers are still choosing it when they have plenty of other options.
What keeps Tesla owners coming back has a lot to do with the and convenience of charging. The Supercharger network is the most straightforward example. With over 65,000 Superchargers globally, it remains the largest and most reliable fast-charging network in the world, and owners who have built their routines around it face a real practical cost when considering a switch. Competitors have made progress, but the consistency, speed, and availability of Tesla’s network is still the benchmark the rest of the industry is chasing. Then there is the software side. Tesla has built a model where the car you own today is functionally different from the car you bought two years ago, through over-the-air updates that add continuous game-changing improvements such as Full Self-Driving that has moved from a driver-assist feature to an increasingly capable autonomous system. For many Tesla owners, leaving the brand means starting over with a car that will not get meaningfully better over time, and that is a trade-off fewer and fewer are willing to make.
