Trucks With Onboard Solar Are Becoming A Thing
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.”

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!

Japanese equipment giant Kubota brought 22 new or updated machines to the 2025 bauma expo earlier this year, but tucked away in the corners was a new retrofit kit that can help existing customers decarbonize more quickly, and more affordably.
No matter how badly a fleet may want to electrify, harsh economic realities and the greater up-front costs typically associated with battery electric remain high hurdles to overcome, but new retrofit options from major manufacturers are popping up to help lower those obstacles.
The latest equipment maker to put its name on the retrofit list is Kubota, who says its kit can be installed by a trained dealer in a single day.
That’s right! By this time tomorrow, your diesel-powered Kubota KX019 or U27-4 excavator (shown) could be fitted with an 18 or 20 kWh li-ion battery pack and electric drive motors and ready to get to work in a low-noise or low-vibration work environment where emissions are a strict no-no. Think indoor precision demolition or historic archeological excavation.
Then, if necessary, it can go right back to diesel power.
From diesel to electric and back again
If that sounds familiar, that’s because we’ve talked about a similarly flexible power solution from ZQUIP. The battery packs and diesel engines are much larger in that application, but the basic sales pitch remains the same: electric when it benefits your operation, diesel it doesn’t.
Kubota says its modular retrofit kits is a response to the increasing global demand for sustainable alternatives by focusing on making machinery that’s flexible and repairable enough to be “reusable,” and offer construction fleet managers a longer operational lifespan, superior ROI (return on investment), and lower TCO (total cost of ownership) than the competition.
Kubota’s solution also notably reduces maintenance costs and operational overheads. With no engine and associated components, servicing time and expenses are considerably reduced, saving customers both time and money. Additionally, with electricity costing far less than fossil fuels, it offers a highly economical advantage.
International Rental News reports that other changes to the excavators include a more modern cab controls with a digital instrument cluster, a 60 mm wider undercarriage for more stability, and an independent travel circuit allows operators to use the boom, dipper, bucket, and auxiliary functions without an impact on tracking performance.
Kubota’s new kit, first shown at last year’s Hillhead exhibition in the UK, will officially be on sale this summer – any day now, in fact – though pricing has yet to be announced.
Electrek’s Take
If you’re wondering how it is that we’re still talking about bauma 2025 a full quarter after the show wrapped up, then I haven’t done a good enough job of explaining how positively massive the show was. Check out this Quick Charge episode (above) then let us know what you think of Kubota’s modular power kits in the comments.

FERC: Solar + wind made up 96% of new US power generating capacity in first third of 2025
Solar and wind accounted for almost 96% of new US electrical generating capacity added in the first third of 2025. In April, solar provided 87% of new capacity, making it the 20th consecutive month solar has taken the lead, according to data belatedly posted on July 1 by the Federal Energy Regulatory Commission (FERC) and reviewed by the SUN DAY Campaign.
Solar’s new generating capacity in April 2025 and YTD
In its latest monthly “Energy Infrastructure Update” report (with data through April 30, 2025), FERC says 50 “units” of solar totaling 2,284 megawatts (MW) were placed into service in April, accounting for 86.7% of all new generating capacity added during the month.
In addition, the 9,451 MW of solar added during the first four months of 2025 was 77.7% of the new generation placed into service.
Solar has now been the largest source of new generating capacity added each month for 20 consecutive months, from September 2023 to April 2025.
Solar + wind were >95% of new capacity in 1st third of 2025
Between January and April 2025, new wind provided 2,183 MW of capacity additions, accounting for 18.0% of new additions in the first third.
In the same period, the combination of solar and wind was 95.7% of new capacity while natural gas (511 MW) provided just 4.2%; the remaining 0.1% came from oil (11 MW).
Solar + wind are >22% of US utility-scale generating capacity
The installed capacities of solar (11.0%) and wind (11.8%) are now each more than a tenth of the US total. Together, they make up almost one-fourth (22.8%) of the US’s total available installed utility-scale generating capacity.
Moreover, at least 25-30% of US solar capacity is in small-scale (e.g., rooftop) systems that are not reflected in FERC’s data. Including that additional solar capacity would bring the share provided by solar + wind to more than a quarter of the US total.
With the inclusion of hydropower (7.7%), biomass (1.1%), and geothermal (0.3%), renewables currently claim a 31.8% share of total US utility-scale generating capacity. If small-scale solar capacity is included, renewables are now about one-third of total US generating capacity.
Solar is on track to become No. 2 source of US generating capacity
FERC reports that net “high probability” additions of solar between May 2025 and April 2028 total 90,158 MW – an amount almost four times the forecast net “high probability” additions for wind (22,793 MW), the second-fastest growing resource. Notably, both three-year projections are higher than those provided just a month earlier.
FERC also foresees net growth for hydropower (596 MW) and geothermal (92 MW) but a decrease of 123 MW in biomass capacity.
Taken together, the net new “high probability” capacity additions by all renewable energy sources over the next three years – i.e., the bulk of the Trump administration’s remaining time in office – would total 113,516 MW.
FERC doesn’t include any nuclear capacity in its three-year forecast, while coal and oil are projected to contract by 24,373 MW and 1,915 MW, respectively. Natural gas capacity would expand by 5,730 MW.
Thus, adjusting for the different capacity factors of gas (59.7%), wind (34.3%), and utility-scale solar (23.4%), electricity generated by the projected new solar capacity to be added in the coming three years should be at least six times greater than that produced by the new natural gas capacity, while the electrical output by new wind capacity would be more than double that by gas.
If FERC’s current “high probability” additions materialize, by May 1, 2028, solar will account for one-sixth (16.6%) of US installed utility-scale generating capacity. Wind would provide an additional one-eighth (12.6%) of the total. That would make each greater than coal (12.2%) and substantially more than nuclear power or hydropower (7.3% and 7.2%, respectively).
In fact, assuming current growth rates continue, the installed capacity of utility-scale solar is likely to surpass that of either coal or wind within two years, placing solar in second place for installed generating capacity, behind only natural gas.
Renewables + small-scale solar may overtake natural gas within 3 years
The mix of all utility-scale (ie, >1 MW) renewables is now adding about two percentage points each year to its share of generating capacity. At that pace, by May 1, 2028, renewables would account for 37.7% of total available installed utility-scale generating capacity – rapidly approaching that of natural gas (40.1%). Solar and wind would constitute more than three-quarters of installed renewable energy capacity. If those trend lines continue, utility-scale renewable energy capacity should surpass that of natural gas in 2029 or sooner.
However, as noted, FERC’s data do not account for the capacity of small-scale solar systems. If that’s factored in, within three years, total US solar capacity could exceed 300 GW. In turn, the mix of all renewables would then be about 40% of total installed capacity while the share of natural gas would drop to about 38%.
Moreover, FERC reports that there may actually be as much as 224,426 MW of net new solar additions in the current three-year pipeline in addition to 69,530 MW of new wind, 9,072 MW of new hydropower, 202 MW of new geothermal, and 39 MW of new biomass. By contrast, net new natural gas capacity potentially in the three-year pipeline totals just 26,818 MW. Consequently, renewables’ share could be even greater by mid-spring 2028.
“The Trump Administration’s ‘Big, Beautiful Bill’ … poses a clear threat to solar and wind in the years to come,” noted the SUN DAY Campaign’s executive director, Ken Bossong. “Nonetheless, FERC’s latest data and forecasts suggest cleaner and lower-cost renewable energy sources may still dominate and surpass nuclear power, coal, and natural gas.”
