Every time I write about solar vehicles, I get the same thing from people in the comments and on social media, like:

“That’s a stupid gimmick that’ll add like a mile a day.”

“What a joke. That can’t even run the air conditioning.”

While these statements have been true for decades, solar technology and EV efficiency have slowly been chipping away at the problem. Now, vehicles like the “never charge” Aptera and the Sono Sion are proving that solar can power at least a good chunk of people’s driving — but can it work for larger vehicles?

The answer isn’t a hard “No” like it once was. The amount of “Yes” is on the rise, even for people who don’t want to drive a “clown truck.”

Sono and ARI Light Delivery Truck

Earlier this month, Sono Motors worked with ARI to add solar to a 458 “Box Body” truck. While not a full-sized truck, or even a normal-sized truck, it’s still an incredibly useful little beast. In cities, at airports, or just for the last mile of package delivery, the 458 Box Body can carry almost 1200 pounds (531 kg) and up to 2.8 cubic meters (about 100 cubic feet) of cargo. It can go a maximum of 80 km/h (about 50 MPH) and has a range of 75–300 miles on a charge.

At full throttle, the 458 Box Truck uses only 7.5 kW of electric power, but most driving would be with far less current. So, it’s really an ideal platform to experiment with solar drive power.

Sono took the stock 458 Box Truck and added solar modules made with ultra-thin, chemically-stressed front glass to provide up to 450 watts of energy at peak performance. Under normal conditions in Munich, they figure that it will add 20 km of range daily without plugging in, and up to 45 km of range under more ideal conditions like you’d find in the US Southwest.

“Sono Solar — Sono Motors’ B2B unit — is a one-stop-shop for vehicle integrated photovoltaics (ViPV) and our aim is to make every vehicle a solar vehicle. The Intersolar exhibition is the perfect platform to show our proprietary technology and services and we are very pleased to be able to present existing partnerships and prototypes like the electric ARI transporter,” says Mathieu Baudrit, Sono Solar Group Lead at Sono Motors.

Fraunhofer Is Testing A Larger Solar Truck

When it comes to cargo trucks, Justin Hammer was right. Size does matter. Don’t let anyone tell you differently. In ‘Murica, we need a big 9,000 pound truck just to go to the store and buy kitty litter. Don’t believe me? Ask GM about the Hummer EV. Clown cars like the 458 Box Truck might be useful for the city parks and recreation department to drive around the baseball fields, or for the airport to stuff tiny meals into planes with, but don’t expect to see them on the road.

When it comes to doing a real man’s man work, we want to be like Rubber Duck in the 1978 movie Convoy. “My daddy always told me to be like a duck. Stay smooth on the surface and paddle like the devil underneath!” If we can’t push 80,000 lb down the road while strung out on caffeine and modafinil (among other things) while eating an echo-modded radio microphone and saying “Breaker one nine!” on 27.185 MHz AM with an illegal 600-watt linear amplifier that makes the lights go dim when you key it up, it’s just not good enough.

I’m kidding about most of the above, of course. While the Hummer EV does weigh in at 9,000 pounds, and we really do love our big vehicles, almost nobody even knows what most of the last paragraph even means. You’ll just have to watch the YouTube video and hang out at truck stops a little more to see if I’m making stuff up.

Many reasonable, sane people who wouldn’t ram the New Mexico State Police or the Illinois National Guard out of the way, and who want to carry cargo for an honest living, do really need a larger vehicle than the 458 Box Truck. Where’s the solar panel for us “Rubber Ducks?”

Fortunately, the industry is working on giving even the biggest trucks some juice from the giant thermonuclear fireball in the sky. Fraunhofer has an electric truck driving on German roads right now with 3500 watts of solar power on the trailer. Sure, it’s no 18-wheeler, but 18 tons GVWR is nothing to sneeze at either. The 3.5 kilowatts of power only takes care of 5–10 percent of the electric truck’s energy needs.

“By successfully putting our high-voltage photovoltaic system into operation, we have achieved our goal of demonstrating the feasibility of vehicle-integrated photovoltaics for heavy-duty electric utility vehicles. The technical components integrated into the truck function as we expected,” said Christoph Kutter, project manager at Fraunhofer ISE.

There is one small safety risk, though. To directly charge the truck’s traction battery, the panels are wired in series, and put out that 3500 watts of power at over 400 volts. In the event of an accident, that’s a lot of juice to be randomly flipping around in the face of emergency workers and good Samaritan types. Fraunhofer thought ahead and installed an automatic disconnect that cuts every solar panel off from the whole system, reducing the voltage down to safe levels.

Feeding 5–10% of the vehicle’s needs from solar might seem sort of silly, but Fraunhofer plans to run the truck hauling real loads for a year on German roads to collect data. By collecting the data on how much solar power ends up being generated, used, and replaced, they can get a much better idea of how to build better solar vehicles in the future as the technology improves.

After all, solar panels are getting better all the time, and it will eventually be possible to take care of a significant portion of the truck’s power. Plus, trucks operating in cities and trucks that spend a lot of time sitting during the day will benefit even more from this technology.

So, fear not, Rubber Ducks. The power of the sun will soon be yours!

Tesla posted record China sales in 2024. But this year is going to be tough as competition heats up

Electric vehicle-maker Tesla’s sales in China climbed to a record high last year. Sustaining that performance in 2025 could prove tricky as competition with homegrown players intensifies, analysts said.

The U.S. electric vehicle maker saw annual sales in China jump 8.8% to a record high of more than 657,000 cars in 2024. In December alone, its sales rose 12.8% from the previous month to 83,000 units, according to Tesla China.

However, Tesla has been losing market share to Chinese new-energy-vehicle players, down from 7.8% in 2023 to 6% in the January to November period last year, according to Bill Russo, founder and CEO of Automobility, who believes Tesla is “struggling to keep pace [with domestic rivals] and has a limited and aging product portfolio.”

Brand resiliency and price cuts have supported Tesla’s sales so far, said Tu Le, founder and managing director of Sino Auto Insights, but he was less certain that Tesla could keep up its momentum in 2025, given the lack of new products and increased local competition, especially from Chinese companies.

Aggressive price war

Tesla slashed the price for its best-selling Model Y in China by 10,000 yuan ($1,364.5) in late December and extended a zero-interest five-year loan plan for car buyers until the end of January.

Its best-selling Model Y now starts at 239,900 yuan after the discount, while the Model 3 sedan starts at 231,900 yuan — Tesla had cut its prices by 14,000 yuan in April — according to its website.

Still that marked a significant premium over a swath of cheaper models offered by Chinese domestic carmakers. BYD, which dominated the market with around 34% market share, prices one of its best-selling models Seagull at 136,800 yuan, and the more affordable Yuan Plus model, starting at 96,800 yuan.

As the price war extends into the new year, Li Auto introduced cash subsidies of 15,000 yuan per purchase along with a three-year zero-interest financing scheme, according to a post last Thursday on its social media Weibo account. Nio also extended a similar three-year zero-interest loan plan for its EV buyers.

The purchasing incentives came on top of Chinese authorities’ push to extend the consumer goods trade-in program, which subsidizes consumers to trade in old cars or appliances and buy new ones at a discount.

The government-subsidized trade-in program could further lower prices for both Model 3 and Model Y by up to 50,000 yuan, Tesla China said.

“Tesla has to discount aggressively to keep pace with the ongoing price war in the market,” Russo noted.

Despite dwindling market share, Tesla is unlikely to lose its ground completely in China, according to Joe McCabe, CEO and president of AutoForecast Solutions, who compared Tesla as “the Apple of cars” — an “early adopter” in the EV space with “phenomenal” technology.

“I don’t think Tesla is at risk of not surviving,” McCabe added, “all [Elon Musk] has to do is drop the price by 5%, because he can, and that will help for little blips.”

Head-to-head race

In addition to lowering prices, Chinese electric carmakers have rolled out a slew of new models, many with fancy in-car features, such as projectors, embedded refrigerators and driver-assist systems.

Meanwhile Tesla has been slow in adopting any of these features, with its product portfolio focused solely on fully electric vehicles, while its homegrown rivals have steered into plug-in hybrid cars and extended-range EV categories.

These more traditional models appeal to buyers who are “still worried about the leap to fully electric [cars],” Sam Fiorani, vice president of AutoForecast Solutions said. “Tesla has no plans for anything other than fully electric vehicles.”

Tesla needs to 'up its game' to retain leadership in EV transition: Investment strategist

The automaker’s plans of launching its full self-driving supervised system still hinges on regulatory permission in China, while several local competitors have made the advanced driver-assistance systems a basic part of their offering, including BYD.

Musk had warned in January that Chinese automakers could “demolish most other car companies in the world” unless regulators intervene with trade barriers, as the Warren Buffet-backed BYD overtook Tesla as the world’s top-selling EV company in the last quarter of 2023.

The U.S. imposed a 100% duty on Chinese EVs last September to protect its homegrown industries from the pricing pressure posed by heavily-subsidized peers from China. The European Union has also moved to impose tariffs as high as 45.3% on Chinese EV cars imported late last year, while Tesla enjoyed a lower tariff rate of 7.8%.

The trade barriers would force Chinese automakers to find buyers at home and in the “smaller, friendlier” foreign markets, adding pressure on Tesla’s sales in China and elsewhere, Fiorani added.

Tesla’s sales of China-made EV cars including exports to foreign markets fell modestly by 0.4% from a year ago to 93,766 units in December, according to CNBC’s calculation of China Passenger Car Association data.

BYD, which is subject to 17% tariff duties for car exports to European Union, still led the rank with 509,440 cars sold in December, a near 50% year-on-year jump.

Bosch teases big announcement on electric bike battery innovation

Bosch eBike Systems plans to announce something new at CES 2025, perhaps related to advances in its electric bicycle battery technology. A cryptic teaser video gives a taste of what’s to come.

In the video seen below, a Bosch PowerPack 800 e-bike battery can be seen along with the words “Protect what is valuable” on either side of the battery.

The clues could lead in several directions, potentially relating to the battery’s safety or to advances in theft prevention.

Is Bosch unveiling potted e-bike batteries?

One potential theory centers around the possibility of Bosch unveiling potted batteries, a design that encases the internal components and battery cells in resin or other solid protective materials. This construction method is highly valued for its resistance to water, shocks, and vibrations, making it ideal for mountain bikers and commuters who ride in challenging environments.

While the concept is not new, it is still uncommon in the electric bicycle battery industry. Last year, the electric bicycle brand Rad Power Bikes unveiled new potted batteries as part of their SafeShield line of batteries.

The practice does raise some concerns regarding the ability to recycle such batteries, but Rad Power Bikes has said that its SafeShield batteries are still recyclable. Accessing the cells is difficult when potted batteries are discontinued, but many battery recycling programs grind up the entire battery and use a series of separators such as magnets, screens, and centrifuges to isolate the important materials for further recycling.

The shift towards potted batteries marks a significant increase in battery safety, especially for riders on rough terrain or who ride in wet environments. Physical damage and water ingress (especially salt water from coastal regions or areas with significant road salt usage) are two leading causes of e-bike battery fires. While such fires are still quite rare considering the large number of e-bike batteries in circulation, addressing those two areas, which are commonly seen in Bosch’s two main markets of electric mountain bikes and commuter e-bikes, could go a long way towards improving safety.

Does Bosch have a new theft protection system?

Another possible interpretation of the teaser could relate to anti-theft technology. Battery theft has become a growing concern for e-bike riders, especially in urban areas where bikes are often left locked up outside. Bosch might be addressing this issue by introducing integrated theft-prevention features.

Potential innovations could include built-in GPS trackers for locating stolen batteries, more tamper-proof locking mechanisms, or even remote disabling capabilities that render a stolen battery unusable.

Other companies, such as the now-defunct Juiced Bikes, have built e-bike batteries with specially designed cavities for concealing Airtags or other location-tracking devices.

While details remain under wraps, Bosch’s teaser has created a buzz in the e-bike community due to the e-bike component maker’s large market share. The official announcement from Bosch is expected soon, and we’ll report back as soon as we know more.

Until then, let’s hear your thoughts in the comment section below. What could Bosch’s engineers be cooking up this time?

Several commodities face headwinds in 2025 — but this metal’s record rally is set to continue

Several commodities face headwinds in 2025 — but this metal's record rally is set to continue

Commodity prices are largely expected to fall in 2025 due to a sluggish global economic outlook and a resurgent dollar, but gold and gas prices are poised to rally this year, according to industry experts.

Commodities had a mixed 2024: While investors flocked to gold to hedge against inflation, commodities such as iron ore fell as the world’s largest consumer of metals, China, struggled with tepid growth. The story this year is likely to be the same.

“Commodities in general will be under pressure across the board in 2025,” said research firm BMI’s head of commodities analysis Sabrin Chowdhury, adding that the strength of the U.S. dollar will cap demand for commodities priced in the greenback. 

Market participants will be keeping an eye on further China stimulus in hopes that it may fuel a recovery in commodities demand in the world’s second-largest economy. 

Oil prices to slip

Crude oil prices last year were dragged down by weak Chinese demand and a supply glut, and market watchers expect prices to remain pressured in 2025.

The International Energy Agency in November painted a bearish oil market picture for 2025, forecasting global oil demand to grow under a million barrels per day. This compares to a two million barrel per day increase in 2023.

Commonwealth Bank of Australia sees Brent oil prices falling to $70 per barrel this year on expectations increased oil supply from non‑OPEC+ countries that’ll eclipse the rise in global oil consumption.

Oil prices year-on-year

BMI said in its December note that the first half of 2025 was likely to see a supply glut as substantial new production from U.S., Canada, Guyana and Brazil comes online. Also, if OPEC+ plans to roll back voluntary cuts materialize, the oversupply will further pressure prices.

BMI noted that the demand picture in 2025 was not clear yet. “Global oil and gas demand remains uncertain, with stable economic growth and rising fuel demand offset by trade war impacts, inflation and contracting demand in developed markets.”

Global crude benchmark Brent was last trading at $76.34 per barrel, around the same levels as it was a year ago in early January.

Gas set to rise

Global natural gas prices have rallied since mid-December 2024, driven by cold weather and geopolitics, Citi analysts said.

Ukraine’s recent halt of Russian gas flow to several European nations on New Year’s Day has introduced greater uncertainty to the global gas markets. As long as the cutoff remains in place, gas prices are likely to remain elevated.

Colder weather for the rest of winter in the U.S. and Asia could also keep prices elevated, said Citi.

BMI forecasts gas prices to rise by about 40% in 2025 to $3.4 per million British thermal units (MMbtu) compared to an average of $2.4 per MMbtu in 2024, driven by growing demand from the LNG sector and higher net pipeline exports. 

U.S. Henry Hub natural gas prices, which was the gauge that BMI referred to, are currently trading at $2.95 per MMbtu.

“LNG will continue to drive new consumption, supported by rising export capacity and strong demand in Europe and Asia,” BMI analysts wrote. 

Gold may add sheen

Gold prices notched a slew of all-time highs last year, and the run of fresh records could extend in 2025.

“Investors are optimistic about gold and silver for 2025 because they are so pessimistic on geopolitics and government debt,” said Adrian Ash, director of research at BullionVault, a gold investment services firm, emphasizing on the yellow metal’s role as a hedge against risk.

Gold prices year-on-year

JPMorgan analysts also expect gold prices to rise, especially if U.S. policies become “more disruptive” in the form of increased tariffs, elevated trade tensions and higher risks to economic growth.  

Gold notched its best annual performance in over a decade last year. Bullion prices rose about 26% in 2024, data from FactSet showed, driven by central bank as well as retail investor purchases.

BullionVault and JPMorgan expect gold prices to go up to $3,000 per ounce in 2025.

Silver and platinum likely to advance

Gold’s poorer cousin, silver, could also see prices rise, especially as demand for solar power — silver is used in building solar panels — remains resilient and the metal’s supply stays limited.

“Both silver and platinum have strong underlying deficit fundamentals, and we think a catch up trade later in 2025, once base metals find firmer footing, could be quite potent,” JPMorgan analysts noted.

Silver is primarily utilized in industrial applications and is frequently incorporated in the production of automobiles, solar panels, jewelry and electronics. It is also needed in building artificial intelligence products and has military applications as well, said CIO of Swiss Asia Capital’s CIO Juerg Kiener.

That said, silver’s upside will be dependent on global industrial demand which will be impacted by Trump’s tariffs, precious metals trading services group MKS Pamp wrote in an outlook report.

Copper faces demand worries

Prices of copper, which is key to the manufacturing of electric vehicles and power grids, may see a dent after shooting to a record high this year on the back of a global energy transition.

“A potential deceleration in energy transition amid Trump’s policy shifts might dampen, to some extent, the ‘green sentiment’ that bolstered prices in 2024,” BMI wrote in a note.

While copper prices rose to a record high in May 2024 largely as a result of a squeezed market, they trended lower for the rest of the year, and will continue to do so, John Gross, president at the eponymous metals management consultancy John Gross and Company, told CNBC.

A cocktail mix of high inflation, elevated interest rates and a stronger dollar will weigh on all metals markets, the metals market veteran said.

Iron ore forecast to drop

Iron ore prices may also slide on the back of an oversupply resulting from Chinese policies and geopolitics. 

“The expected U.S. tariffs on China, changing nature of Chinese stimulus and new low-cost supply [will] push the market into further surplus,” Goldman Sachs said, forecasting prices to decline to $95 per ton in 2025.

This despite China likely to import record amount of iron ore this year, according to Reuters. Iron ore prices fell over 24%, according to data from FactSet.

Cocoa and coffee

Cocoa and coffee prices stand out amongst the soft commodities basket, having scaled record highs in 2024 fueled by adverse weather conditions and supply tightness in key producing regions. But demand may taper in 2025.

“Given that these commodities are trading at levels well above cost of production, we expect production to expand and demand to contract in the coming year,” Rabobank researchers said.
