It’s back! The electric mini-truck that keeps on giving has another fun trick up its sleeve. With a bit of DIY magic, I was able to outfit my Chinese mini-truck with a solar panel that can trickle charge it from the sun.
If you’re aren’t familiar with this unassuming little mini-truck, then here’s the background: I found it on Alibaba back in 2021 and paid the Chinese vendor it came from $2,000 to make it mine.
It went through a long saga of being shipped to the US, which cost slightly more than the truck itself. But it eventually arrived in Florida where it’s been living out a hard working yet rewarding life on my parent’s ranch. There it mainly serves as a work truck on the property, though sometimes it heads out just to delight the neighbors. Everyone loves this quirky little thing.
The electric drive means that it is quiet, largely maintenance-free, and doesn’t require any trips to the gas station to fill up.
That last one is important since it isn’t even street legal, and hence why it lives its life off-road as a work truck.
The fairly large (for a mini-truck) 6,000 Wh battery generally provided around a week or two of use before needing to be recharged from a typical 120V wall outlet.
That was fine, though it was a bit annoying to wait all day for it to charge.
So I decided to try to take advantage of the plentiful sun that bakes its roof rack each day while it sits outside. To do so, I got a small solar panel to mount onto the roof rack.
I figured if I could just let it trickle charge while it’s sitting out in the sun, then I wouldn’t actually need to plug it in for a big charge of the LiFePO4 battery nearly as often.
You can follow along with the process of installing the solar panel on the truck in a video I filmed of the project, or just keep reading for the details.
The largest panel I could find that didn’t extend past the existing roof rack was a 50W Renogy solar panel. Not exactly huge, but it would be just fine for trickle charging. Assuming around 35W of solar energy (they don’t call Florida the Sunshine State for nothin’!) for 8 hours a day, I figured I’d get nearly 300 Wh of trickle charging per day.
Considering the truck only drives a few miles per day while it stays within a 10 acre ranch, that would probably account for around half of its daily use. It wouldn’t take it completely off-grid, but it should stretch out the time between charges by around double. And the panel would be small enough that it wouldn’t impact anything else on the truck or extend past the confines of the existing roof rack.
I was able to mount the solar panel by using PVC pipe to create struts across the roof rack. After painting them black, they basically looked like the existing steel tubes and make the installation appear more like a factory job.
The pipes also allowed me to angle the panel slightly, meaning I can park the truck facing north when I’m not using it and get a nice southernly angle for higher solar efficiency.
To increase the roughly 18VDC coming out of the solar panel to match the charge voltage needed by my 60V battery in the mini-truck, I used a solar charge controller. It’s the same one I used in a previous solar electric bike project, and it’s way more powerful than I need. But the extra power means that if I ever want to create a carport or other installation with a few larger solar panels on it, I could plug them in directly to the truck and get a higher charging rate when parked near the solar array.
The actual process of connecting everything is pretty darn simple. The solar panels plug into the charge controller, which itself plugs into the battery’s charging port. I was able to access the charging port by using a spare plug under the mini-truck’s charging cap (I still don’t know why the mini-truck came with two different charging ports wired to the same circuit, but I was happy it did). The most difficult part was just peeling back the interior lining of the truck’s cab to hide the wiring that ran up to the solar panel.
With the installation complete, testing showed that in most conditions I could get between 30-35W of power. At one point I reached 45W when the sun was its highest point in the sky, though 35W was a more realistic figure on average.
Since the solar panel installation, I’ve found that the charging period has basically doubled.
If my family charged the truck around once every 10 days or so in the past, now we can get away with doing it once every three weeks or so.
A panel that was large enough to completely charge the truck would be nice, but I didn’t want one so big that it could get in the way of the bed since we use the truck nearly daily for hauling things around the property.
The bed also has a hydraulic ram that lifts it up about 45-degrees in dump truck form, and so I couldn’t have a panel extend too far back.
I’d say that the project was quite successful, and it demonstrates that solar charging on vehicles can be effective if the vehicle is low enough power (my truck is around 5 hp).
Conventional solar electric cars can’t really compare, since a day of sun just isn’t enough to fill a reasonable portion of their massive batteries. But if you’ve got a small EV like a mini-truck or an e-bike, especially one that doesn’t need to go too far each day and generally stays in one area like this, you can actually make an impact even with a relatively small solar panel.
For anyone who ever wanted to try a DIY solar charging project like this, I’d definitely recommend giving it a shot. It’s surprisingly simple and easy to do. It’s also hard to describe the rewarding feeling of stepping back to admire your work afterwards, watching your device “magically” charging without being plugged in. Or at least, without being plugged in to the wall.

DUBAI, United Arab Emirates — The wealthy Arab Gulf states are in a better position than many other regions of the world to manage the economic impact of U.S. President Donald Trump’s tariffs, economists and regional investors say. But a shaky outlook for the price of oil could put some countries’ budgets and spending projects at risk.
Saudi Arabia, the United Arab Emirates, Bahrain, Kuwait, Oman, and Qatar make up the Gulf Cooperation Council. Together, they comprise around $3.2 trillion in sovereign financial assets, accounting for 33% of the total sovereign assets worldwide, according to GCC Secretary-General Jasem Mohamed Albudaiwi.
The GCC also holds approximately 32.6% of the world’s proven crude oil reserves, according to the Statistical Center of the Cooperation Council for the Arab States of the Gulf.
That makes it both an asset for the Trump administration as well as vulnerable to its policies, as Trump has long pushed for OPEC, the oil producer alliance led by Saudi Arabia, to pump more oil to help lower oil prices and offset inflation in the U.S.
A lower oil price, however, can significantly impact the budget deficits and spending plans for those countries, whose economies — despite diversification efforts — still rely heavily on hydrocarbon revenues.
“I do think the Middle East, with the deep relationship with the U.S. that they have, should come out okay,” Powell told CNBC’s “Access Middle East” on Monday.
“I think we’re all going to be swept into the maelstrom over the next short period of time. That’s inevitable. But the Middle East, with the balance sheet strength that they have, with the energy support that they still have, providing funding on a near ongoing basis … for me, the Middle East — maybe not today, but over time — should be a relative winner within that mix” when it comes to emerging markets, Powell said.
In considering what the firsthand impact of tariffs might be, Monica Malik, chief economist at Abu Dhabi Commercial Bank, noted that the U.S. is not a major export market for the Gulf.
“The GCC should be in a relatively favourable position to withstand headwinds, especially the UAE,” she wrote in a report for the bank on Friday.
While the region faces the blanket 10% universal tariff as well as previously imposed tariffs on all foreign steel and aluminum — products that the UAE and Bahrain both export — “we expect the direct impact to be relatively contained, as the US is not a key destination for Gulf exports, averaging just c.3.7% of the GCC’s total exports in 2024,” she said.
Saudi Arabia needs oil at more than $90 a barrel to balance its budget, the International Monetary Fund estimates. Goldman Sachs this week lowered its oil price forecast for 2026 to $58 for Brent and $55 for U.S. benchmark WTI crude. That’s a significant move lower from its forecast just last Friday of $62 for Brent and $59 for WTI in 2026.
“A weaker global demand and greater supply adds downside risk to our Brent forecast for 2025, though we wait for more market clarity before making any changes,” ADCB’s Malik told CNBC on Monday. OPEC+ is meant to increase oil production levels again in May, and she predicts the group will pause that plan if crude prices stay where they are or fall further.
“Our greatest concern would be a sharp and sustained oil price fall, which would require a reassessment of spending plans – government and off budget – including capex, while also potentially affecting banking sector liquidity and wider confidence,” Malik warned.

The United Nations shipping agency is on the cusp of introducing binding regulations to phase out fossil fuel use in global shipping — with the world’s first-ever global emissions levy on the table.
The International Maritime Organization (IMO) will this week hold talks at its London headquarters to hammer out measures to reduce the climate impact of international shipping, which accounts for around 3% of global carbon emissions.
Some of the measures on the table include a global marine fuel standard and an economic element, such as a long-debated carbon levy or a carbon credit scheme.
If implemented, a robust pricing mechanism in the shipping sector would likely be considered one of the climate deals of the decade.
An ambitious carbon tax is far from a foregone conclusion, however, with observers citing concerns over sweeping U.S. tariffs, a brewing global trade war and reluctance from members firmly opposed to any kind of levy structure.
Sara Edmonson, head of global advocacy at Australian mining giant Fortescue, described the talks as “absolutely historic,” particularly given the potential for a landmark carbon levy.
“I think it would be an absolute game-changer. No other industry on a global level has made a commitment of this size and I would argue most countries haven’t made a commitment of this size,” Edmondson told CNBC via telephone.
She added, however, that “the jury is still very much out” when it comes to a global carbon price.
It’s not really a question of whether they get agreement, it’s just how ambitious it is, how effective it is and how many unhappy people there are.

“There are also a lot of discussions around levy-like structures because obviously the word levy in very polarized countries like the U.S., like Australia and even in China, can be very challenging. But I think there are really good discussions around levy-like structures that would ultimately have an equivalent effect,” Edmondson said.
The IMO’s Marine Environment Protection Committee (MEPC) is scheduled to conclude talks on Friday.
If adopted, it would be “the first industry-wide measure adopted by a multilateral UN organisation with much more teeth than we could get in the UNFCCC process,” Regenvanu said.
Delegates at the IMO agreed in 2023 to target net-zero sector emissions “by or around” 2050 and set a provision to finalize a basket of mid-term carbon reduction measures in 2025.
The international shipping sector, which is responsible for the carriage of around 90% of global trade, is regarded as one of the hardest industries to decarbonize given the vast amounts of fossil fuels the ships burn each year.
Angie Farrag-Thibault, vice president of global transport at the Environmental Defense Fund, an environmental group, said a successful outcome at the IMO would be an ambitious global fuel standard and a “decisive” economic measure to ensure shipping pollution is significantly reduced.
“These measures, which should include a fair disbursement mechanism that uses existing climate finance structures, will encourage ship owners to cut fossil fuel use and adopt zero and near-zero fuels and technologies, while supporting climate-vulnerable regions at the speed and scale that is needed,” Farragh-Thibault said.
The US wind industry installed just 5.2 gigawatts (GW) in 2024 – the lowest level in a decade, according to Wood Mackenzie’s new US Wind Energy Monitor report. Installations are expected to rebound in 2025, but the real concern lies in US wind’s sharply downgraded 5-year outlook. As for the reason behind that bleak forecast, we’ll give you one guess as to why, and it starts with a T.
Wood Mac reports that 3.9 GW of onshore wind came online last year, along with 1.3 GW of onshore repowers and 101 megawatts (MW) of offshore wind.
Onshore wind
The US is expected to achieve more than 160 GW of installed onshore capacity by 2025, and onshore growth is projected to bounce back from 2024 and surpass 6.3 GW this year.
“The cliff in 2023 and 2024 created by the Production Tax Credit (PTC) push in 2022 will come to an end,” said Stephen Maldonado, research analyst at Wood Mackenzie. “Despite the uncertainty created by the new administration, the massive number of orders placed in 2023 culminating in projects now under construction support the short-term forecast.”

The pipeline for onshore has 10.8 GW currently under construction through 2027, with another 3.9 GW announced.
GE Vernova led onshore wind installations in 2024 with 56% of the market and will continue to lead in connections for the next five years. It was followed by Vestas (40%) and Siemens Gamesa (4%).
Offshore wind
Offshore wind is projected to increase in 2025 as well, with 900 MW of installed capacity, up from a disappointing 101 MW in 2024. However, several projects have been shelved in the wake of Trump’s anti-wind executive orders, which downgraded the five-year outlook by 1.8 GW.
Electrek’s Take on US wind’s 5-year outlook
According to Wood Mac, 33 GW of new onshore wind capacity will be installed through 2029, along with 6.6 GW of new offshore capacity and 5.5 GW of repowers. However, due to Trump’s anti-wind policy and economic uncertainty, this five-year outlook is 40% less than a previous total of 75.8 GW. Growth will happen, but it’s going to be slower.
The main reason is Trump’s flourish of his Sharpie on executive orders that include “temporary” withdrawal of offshore wind leasing areas and putting a stop to onshore wind on federal lands. Plus, firing all those federal employees will likely make permitting wind farms a slower process. (Trump just wrote more executive orders today allowing coal projects on federal lands; he won’t have federal employees to issue permits for those, either.) He’s worked to throw up obstacles for wind projects in favor of fossil fuels. He won’t stop the wind industry, but he’s managed to get some projects canceled, and he’ll make things more of a slog over the next few years.
