Cuba’s iconic 1950s Chevrolets and Fords are finally throwing in the towel. They aren't dying because of old age—Cuban mechanics have spent decades proving they can fix literally anything with baling wire and sheer willpower. They are dying because there is simply no gas left to burn.
A brutal cocktail of economic stagnation and aggressive geopolitical moves has choked off the island’s fuel supply. In January, the U.S. government threatened heavy tariffs on any country selling oil to Cuba. The results were immediate. An island that used to see eight massive oil tankers dock every month saw exactly one arrive in late March. That is a drop-off you can't spin.

When you only produce about 40% of the fuel your entire population needs to run, a sudden drop in imports freezes everything. Public buses stopped running. Garbage piled up on street corners. The national power grid collapsed into a mess of rolling blackouts that now regularly swallow 20 or more hours of every single day.
Yet, if you walk down Avenida 100 or Boyeros in Havana right now, the streets aren't empty. They are buzzing. Hundreds of thousands of people are moving every single day on a new fleet of Chinese-built three-wheeled electric tricycles. When the blackouts made plugging these trikes into the wall impossible, owners didn't park them. They clamped massive, residential-grade solar panels directly onto the roofs. Additional insights regarding the matter are detailed by TIME.
The $500 Hack Keeping Havana Moving
The math of running an electric vehicle in a country without electricity is fundamentally broken. You can't charge a battery if the outlet in your house is dead all day. That is why the sudden explosion of mobile solar power across the capital is a matter of survival, not an eco-friendly lifestyle choice.
Drivers are buying Chinese trikes from brands like Zonsen, Jinpeng, or the locally assembled Vedca. These rigs usually arrive with standard lithium or gel batteries and cost anywhere from $2,000 to $4,000. For a state worker making an average of $10 a month, or even a private-sector employee bringing home $40, that price tag is a fantasy. People are selling their old gas cars to fund them, using money sent from family in Panama and Miami, or reinvesting every dime of small-business profits.
But buying the trike is only half the battle. To actually use it, you need to call someone like Carlos Álvarez or Yadán Pablo Espinosa.
Espinosa is a 21-year-old entrepreneur running an improvised workshop out of his family’s yard in the Arroyo Naranjo district on the southern edge of Havana. Alongside his father, his three brothers, and a close friend, Espinosa has been cranking out custom steel mounting brackets to turn these commuter trikes into rolling solar charging stations.
The modification costs about $500. It involves bolting a massive 550-watt to 650-watt photovoltaic panel directly above the driver’s head. In the brutal Cuban summer, that panel serves a double purpose. It acts as a heavy awning, offering shade from the baking sun and cover from sudden afternoon downpours, while sucking down raw energy.
How Mobile Solar Works on the Street
You can't expect a single rooftop panel to completely replace a wall charger. A 600-watt panel sitting under five hours of solid Havana sunlight generates roughly 3 kilowatt-hours of power. That isn't enough to magically fill a completely dead battery from scratch while hauling tons of weight, but it completely changes the operational calculus for a working driver.
Espinosa’s wiring setup routes the incoming solar juice directly into the electric motor while the tricycle is rolling down the street. This direct feed takes the immediate load off the main battery pack. When the driver stops to wait for passengers or unload cargo, the system automatically redirects that solar flow back down into the battery cells.
Evanys Peréz, a local operator, notes that the setup can push a tricycle's operational range up to 90 miles on a sunny day. Instead of constantly watching a battery gauge drop with an anxious eye, drivers can keep their wheels turning. It turns a vehicle that was totally dependent on a broken municipal power grid into an independent unit.
The High Cost of Surviving a Shortage
Don't mistake this grassroots ingenuity for a comfortable utopian transition. Riding in a solar trike is slow, loud, hot, and distinctly bumpy. It is simply the only option left when the alternative is walking miles through the heat.
The economic pressure is shifting entirely onto the backs of working-class commuters. Take Berta Ferrer, a 52-year-old store clerk who travels to her job in central Havana four days a week. With no public buses available, she relies on these solar-powered three-wheelers to get to work.
A single fixed-route ride costs her roughly 500 Cuban pesos. That is less than $1 in American terms, but when your monthly income hovers around $10 to $40, spending that much money just to get to a shift is a massive blow. "If you can pay for it, you just take it," Ferrer says. "Otherwise you can't go anywhere."
The trikes have quickly expanded far beyond simple passenger transit. Small-business owners like Ricardo Quintero use their modified three-wheelers to haul fresh produce from rural farms straight to family-run vegetable stands in the city. In several dense Havana neighborhoods where city infrastructure has completely ground to a halt, the local government has even resorted to using these solar trikes to collect residential garbage.
What This Grid Collapse Teaches Us About Real Resilience
The sudden pivot toward mobile solar in Cuba highlights a fascinating quirk in how green technology actually rolls out during a crisis. Large-scale government plans take time, capital, and steady supply lines—three things Cuba completely lacks right now. The state-run grid did manage to scale its connected solar capacity over the last couple of years, hitting peak generation days above 800 megawatts, but it still isn't enough to stop the daily rolling blackouts.
True resilience is happening from the bottom up. It is happening because a 21-year-old mechanic built a jig in his backyard to weld iron frames for imported Chinese panels. It works because it solves a desperate, immediate problem: keeping the food moving and the workers employed today, not ten years from now.
These solar-roofed trikes aren't polished showroom vehicles. They are heavily scratched, loud, and built out of necessity. But they prove that when a centralized energy system completely fails, people will find a way to harvest their own power straight from the sky to keep their lives moving.
If you are looking to build out your own off-grid backup mobility or want to understand how to maximize small-scale solar panels on utility vehicles, look closely at what these Cuban workshops are doing. Focus on low-voltage, direct-to-motor delivery systems that reduce battery strain during daylight hours. Keep your mounting brackets lightweight but heavy-duty enough to handle rough, unpaved roads. Most importantly, design your setups to use standard, easily sourced residential panels rather than specialized automotive solar kits that are impossible to repair on your own.
