After one of my most recent Alibaba import adventures, I was left with a shipping container in my yard. These engineering wonders are great for many uses outside of merely transferring goods around the world, with one of the most common secondary uses being watertight storage units. That seemed like a great idea to put to use for all of my electric “toys”. Between my electric bikes, e-motorcycles, e-ATVs, electric tractors, and a few other things I’m probably forgetting, having a weather-sealed, solar-powered off-grid charging shed would be a big benefit. And if I could add an air-conditioning unit to keep the machines from baking in the sun (and function as a dehumidifier at the same time), then all the better. As it turned out, the project was a lot easier than I expected. Here’s how I did it.
There are many ways to skin a cat, and even more ways to add solar power to a shipping container.
To be fair, I cheated a bit. Well, not really cheated, but I just went with a retail solar generator system instead of DIYing that part myself from à la carte components. It’s more expensive since you’re paying for a pre-designed and engineered solution, but damn if it doesn’t make it easy! To save a bit of money instead, you can source your own solar panels, solar charge converter, batteries, inverter, and wiring, then make it all play together.
For me and my limited time, an offer from Pecron for a solution that would do all of that for me sounded perfect, so I went with Pecron’s system.
To make it all work as a solar shed, I’d have to mount the various components around the container. I started with the solar panels, which would need a frame. I used pressure-treated 2x4s to build a pair of mounts for the solar panels, each of which would hold three 200W panels.
With 1,200W of theoretical power (and probably more like 900W of solid real-world Florida solar energy), that would be a decent flow rate.
The panels I used are Pecron’s folding panels, which aren’t really meant for this type of long-term permanent installation. They should work, it’s just that you’re not really taking advantage of their folding nature.
They’re really designed for camping and other mobile scenarios where you’d want the ability to pack up and move your solar setup with ease.
You can imagine that with a setup like this, you could easily set up a 1,000-ish watt solar array at your campsite or off-grid cabin for a few days, then stow it all away in your trunk again later.
I mounted the panels using screws and big fender washers to hold them to the wooden panels. You can see it in more detail in my video of the project.
I know that everyone and their brother is going to ask me why I didn’t put the panels on an angle. And the answer is to hopefully give them better wind protection.
As I mentioned, these aren’t really designed for permanent installation, and thus they don’t have rigid frames. They’re pretty rigidly mounted to the wooden frames now, and the frames are lashed to the container, but it’s still a giant sail.
We occasionally get storms with pretty decent gusts, and so I wanted the panels flat to not give the horizontal gusts a surface to push against.
Angling the panels south would have been slightly more efficient, but the site is within spitting distance of the southernmost point in the US, so the efficiency difference of flat vs angled panels isn’t as big as if this was in Maine.
From there I had to get the wiring set up to feed my batteries. Here is where the beauty of the pre-built system really shows. All of the panels are wired for the inverter/battery/charge controller gear (which is an all-in-one unit) and the kit includes all of the adapters.
However, because I had to run the wires much further, I bought a set of 20 ft MC-4 solar panel extension wires. That allowed me to run all of the panels in parallel and then send them on a long enough run to make it through the existing vent hole in the side of the container. I had to drill out the vent hole a bit, and despite it not looking like it, I did put a small drip loop in the wires to prevent rainwater from running down the cables and into the container.
It’s been sitting there through plenty of rainy days over the last month, and not a drop of water has entered the container through the hole for the wires.
Between the three of them, I’d have around 8 kWh of storage capacity. The 1,200W solar array should be able to nearly fill that entire battery bank with a solid day of strong Florida sun, though it’s pretty rare that I’d even use the entire 8 kWh in a day anyway.
The three units are all designed to plug into each other and cascade power between them, making this a simple operation. I literally just plugged in the wires and it worked like magic. I don’t mind getting custom, and I’ve got an engineering degree on my shelf that says I enjoy designing solutions, but sometimes it’s just nice to have something arrive ready to work.
To support them all and keep them off the floor so they don’t cut into my valuable storage space, I built a hanging shelf for them. That’s probably 180 pounds of batteries all together, so the shelf is made out of C-channel galvanized steel and hung from chains.
Next came the air conditioning.
I got one of the cheapest portable air conditioning units on Amazon I could find, and despite now realizing that was probably a bad idea, from an efficiency standpoint, it seems to work pretty well.
I should have gone with a small mini-split type of air conditioning unit, would would have been much more efficient. But I’m generating way more solar power than I can possibly use in this off-grid container, and so peak efficiency is less important to me.
For this cheap portable unit, I had to cut a hole in the side of the container for the hot exhaust air to flow, then drill a smaller hole for the condensation tube to drain.
Despite not being the most efficient solution, it quickly cools the air in there (even if it is also sucking some outside air in through the container’s vents). It also acts as a dehumidifier, which is perhaps even more important to me, as my electric toys are likely just as unhappy about being in a super humid environment as they are about just being hot.
In the end, it all works! I mean, I took the easy way out with the Pecron system, but it’s still a cool feeling to start with a bare shipping container and end up with an off-grid solar charging shed that you put together with your own two hands.
With 8 kWh of stored energy and nearly 1,000W of real-world power in direct sun (and often 600-800W in less-than-ideal conditions), this is a seriously powerful system for just charging up all my EVs.
This could power a tiny home or other small off-grid setup like a hunting cabin. For me though, I’ll start with just keeping my electric tractors and motorcycles charged!

In a high-tech move that we can all get behind and isn’t dystopian at all, the City of Barcelona is feeding camera data from its city buses into an advanced AI, but they swear they’re not using the footage to to issue tickets to bad drivers. Yet.
UPDATE 06DEC2025: the ticket bot cometh to Chicago.
Last month, the Chicago Transit Authority (CTA) contracted with Hayden AI to equip six of its transit buses with AI-powered license plate readers intended to target illegally parked vehicles in an area bound by North Avenue, Roosevelt Road, Lake Michigan and Ashland Avenue.
As with similar pilots in Barcelona and NYC, the Hayden AI technology captures information from vehicles illegally blocking bus and bike lanes, then submits its “findings” to a human reviewer for confirmation. If the reviewer agrees with the AI, they can issue a fine of $90 for parking in a bus lane, $250 for bike lane obstruction, $50 for parking in expired meters outside of the central business district, and $140 for personal vehicles parked in commercial loading zones.

Despite those hefty fines, Chicago Mayor Brandon Johnson is quick to point out that the goal of the program isn’t to generate revenue.
“Every Chicagoan deserves a transportation system that is safe, reliable, and efficient,” said Mayor Johnson, in a statement. “By keeping bus and bike lanes clear of illegally parked vehicles, the Smart Streets pilot helps us protect our most vulnerable road users while improving the daily commute for riders across the city.”
The official release makes no mention of the fact that Hayden AI’s system generated nearly $21 million in revenue for the city in just a few months, despite the fact that thousands of those ticketed weren’t doing anything wrong.
We wrote about some of these issues back in Jun. You can read that original article, below, and let us know what you think of Chicago’s “non-revenue” claims in the comments.

Barcelona and its Ring Roads Low Emission Zone have earned lots of fans by limiting ICE traffic in the city’s core. The city’s latest idea to promote mass transit is the deployment of an artificial intelligence system developed by Hayden AI for automatic enforcement of reserved lanes and stops to improve bus circulation – but while it seems to be working as intended, it’s raising entirely different questions.
“Bus lanes are designed to help deliver reliable, fast, and convenient public transport service. But private vehicles illegally using bus lanes make this impossible,” explains Laia Bonet, First Deputy Mayor, Area for Urban Planning, Ecological Transition, Urban Services and Housing at the Ajuntament de Barcelona. “We are excited to partner with Hayden AI to learn where these problems occur and how they are impacting our public transport service.”
Currently operating as a pilot program on the city’s H12 and D20 bus lines, the system uses cameras installed on the city’s electric buses to detect vehicles that commit static violations in the bus lanes and stops (read: stopping or parking where you shouldn’t). The Hayden AI system then analyses that data and provides statistical information on what it captures while the bus is driving along on its daily route.
Hayden AI says that, while it photographs and records video sequences and collects contextual information of the violation, its cameras do not record license plates or people and no penalties are being issued to drivers or owners of the vehicles.
So far so good, right? But it’s what happens once the six mont pilot is over that seems like it should be setting off alarm bells.

The footage is manually reviewed by a Transports Metropolitans de Barcelona (TMB) officer, who reportedly reviewed some 2,500 violations identified by AI in May alone. But, while the system isn’t being used to issue violations during the pilot program, it easily could.
And, in fact, it already has … and the AI f@#ked up royally.
AI writes thousands of bad tickets
NYC issued hundreds of thousands of tickets; via NBC.
When AI was given the ability to issue citations in New York City earlier this year, it wrote more than 290,000 tickets (that’s right: two-hundred and ninety thousand) in just three months, generating nearly $21 million in revenue for the city. The was just one problem: thousands of those drivers weren’t doing anything wrong.
What’s more, the fines generated by the AI powered cameras were supposed to be approved only after being verified by a human, but either that didn’t happen, or it did happen and the human operator in question wasn’t paying attention, or (maybe the worst possibility) the violations were mistakes or hallucinations, and the human checker couldn’t tell the difference.
In OpenAI’s tests of its newest o3 and o4-mini reasoning models, the company found the o3 model hallucinated 33% of the time during its PersonQA tests, in which the bot is asked questions about public figures. When asked short fact-based questions in the company’s SimpleQA tests, OpenAI said o3 hallucinated 51% of the time. The o4-mini model fared even worse: It hallucinated 41% of the time during the PersonQA test and 79% of the time in the SimpleQA test, though OpenAI said its worse performance was expected as it is a smaller model designed to be faster. OpenAI’s latest update to ChatGPT, GPT-4.5, hallucinates less than its o3 and o4-mini models. The company said when GPT-4.5 was released in February the model has a hallucination rate of 37.1% for its SimpleQA test.
I don’t know about you guys, but if we had a local traffic cop that got it wrong 33% of the time (at best), I’d be surprised if they kept their job for very long. But AI? AI has a multibillion dollar hype train and armies of undereducated believers talking about singularities and building themselves blonde robots with boobs. And once the AI starts issuing tickets to the AI that’s driving your robotaxi, it can just call its buddy AI the bank to send over your money. No human necessary, at any point, and the economy keeps on humming.
But, like – I’m sure that’s fine. Embrace the future and all that … right?

The Japanese agriculture equipment experts Kubota are partnering with Norwegian tech startup Kilter to co-develop, pilot, and promote the new Kilter AX-1 ultra high-precision weeding robot across Europe.
To accomplish those goals, the Kilter AX-1 uses a patented tech package it calls “Single Drop Technology.” Single Drop Technology combines AI weed recognition and ~6 mm placement accuracy to deliver micro-doses directly to weeds, protecting the crop and minimizing the impact to the surrounding soil.
Getting that 6 mm droplet application wasn’t easy. “You can’t buy a field-ready droplet applicator off the shelf,” Anders Brevik, CEO of Kilter, told AgTechNavigator. “We had to design one that survives years of dust, vibration, temperature swings, and long operating days, while keeping droplet size, timing, and placement consistent. That takes deep agronomy knowledge, a lot of engineering, and thousands of hours of field testing.”

Kilter says growers can reduce herbicide use by up to 95% by adopting the new AX-1, shifting selectivity from chemistry to smart application.
Kubota Europe’s Smart Farming Solutions Division, launched back in 2024, is working with the company’s European dealer network to train up sales staff and integrate the Kilter robot into Kubota’s broader farm solutions portfolio. There’s no word, yet, on pricing or if/when we’ll get the Kilter in North America.

Autonomous electric tractor concept; by John Deere.
Energy independence and cost control are top of mind for farmers, and more companies are rolling out electric equipment that can be charged by solar, wind, or even on-farm biogas. With the debut of its latest next-generation electric tractor at Agritechnica last month, John Deere is signaling that it intends to lead that revolution.
John Deere says the E-Power electric tractor prototypes that it’s been quietly teasing since 2022 will be as quiet as a car, as easy to drive as a golf cart, and require minimal upkeep – and all while providing the same performance as the company’s beloved diesel tractors.
“Our goal with the E-Power tractor is to ensure it performs the same jobs as its diesel counterparts and works with the same implements, while unlocking incremental value,” explains Derek Muller, business manager for battery electric vehicle systems at John Deere. “Through our electric lineup, we’ll look to reduce operational and maintenance costs, deliver powerful and reliable performance, and intuitive operation.”
The latest electric John Deere tractor prototype, recently unveiled at Agritechnica, is equipped with a 100 hp drive motor and two, additional motors. One 130 continuous hp electric motor for the PTO, and a third for the hydraulic pump. They’ll draw power from up to five KREISEL li-ion battery packs, allowing customers significant pricing flexibility based on their ability to determine how much power and run time they need (and are willing to pay for) to get their jobs done.

The customization will go well beyond just battery size. Deere plans to offer customers a number of different tractor and equipment options, and keep costs competitive by basing them on a vehicle common architecture.
“John Deere aims to develop a single electric concept that customers can configure to their own needs,” writes Bob Karsten, at Future Farming. “Buyers will be able to choose the number of batteries (up to five, totalling 195 kWh), the axle type (narrow or wide track), and the cab (either an orchard cab or the familiar 5M cab). In essence, buyers select their preferred battery capacity. With the largest battery (195 kWh), the tractor can operate for eight hours. The target is to enable fast charging up to 80% in 30 minutes.”
Deere revealed one version of that upcoming electric tractor (above) at Agritechnica last week, but despite being an early prototype, it’s a fully functional piece that’s already seen duty with some of John Deere’s most trusted customers.
Daniel, an orchard customer from California, said his experience with the electric tractor led him to believe it could help ease training new operators, “I do think the tractor is much easier for drivers to understand it and to drive it. It would take less time to teach them [operators] how to use it.”
Tyler, a vineyard customer in California, believes that a new electric tractor could help his operation meet its sustainability goals, “When we look at our carbon footprint, greenhouse gas emissions, we want to try and reduce those as we run our equipment to farm our vineyards, we want to be conscious of the community at large.”
You can check out a quick, virtual walkaround of John Deere’s E-Power electric tractor concept in this (admittedly older) video released around the ACT Expo, and expect more details and possible configurations at the upcoming CON/AGExpo conference in March.
