If you’ve spent any time road-tripping an EV across Europe, you already know the drill: fast chargers are plentiful—until you actually want one that doesn’t cost the better part of a euro per kilowatt-hour. In most EU countries, anything under €0.50/kWh at a DC fast charger feels like spotting a unicorn at a rest stop. Promises of “cheap solar charging” abound. Actual delivery? Not so much.
Except in Katrineholm, Sweden.
This small town in the country’s south has quietly become home to what might be the cheapest fast-charging setup in Europe. The ETC Solpark charging station offers DC fast charging for just €0.15 per kWh during daylight hours. That’s not a typo, not a temporary promo, and not some accounting trick involving certificates or offsets. It’s fast charging, powered directly by the sun, at a price that makes the rest of Europe look like it’s gouging.
The secret isn’t complicated—it’s just rare. ETC Solpark generates its own electricity on site using a dedicated solar power installation located right next to the chargers. No grid middlemen. No peak pricing gymnastics. No greenwashing. Just electrons going straight from solar panels into EV batteries.
“We launched this offer recently and we’re already seeing a huge number of people coming here to charge their vehicles—more than we expected,” says Gahangir Sarvari, manager of ETC Sol. That reaction isn’t surprising. At €0.15/kWh, you’re paying less to fast-charge than many drivers pay to charge at home, let alone on a 150-kW DC unit.
Yes, you read that right: 150 kW. This isn’t a sleepy AC charger tucked behind a grocery store. The site features two 150-kW fast chargers capable of charging up to four EVs simultaneously. Plug in during the day, and you’re getting proper highway-speed charging for a price that feels like it came from a decade ago.
Sarvari puts it bluntly: “Since we produce electricity ourselves, we can maintain the lowest price on the market. It is more profitable for us to consume it at the charging station itself than to sell it to the grid, even at such a low price.”
That single sentence quietly exposes a major flaw in how EV charging is usually done. When solar producers sell power back to the grid, margins are thin and pricing is volatile. Use that same electricity directly—especially for something as energy-hungry and high-margin as fast charging—and suddenly the economics flip. Cheap for drivers, sustainable for operators.
The station has been operating since mid-October and has already delivered around 4,000 kWh. That’s pocket change compared to Europe’s mega-charging hubs, but for a local, independently operated project, it’s a strong start—and proof that demand follows price.
There is, of course, a catch. The €0.15/kWh rate is only valid between 8:00 a.m. and 4:00 p.m., when solar production is strongest. Outside those hours, the price jumps to €0.43/kWh. Even then, it remains competitive with most public fast chargers across the EU. Unsurprisingly, nearly everyone charges during the cheap window. According to ETC Sol, about 99 percent of charging happens during daylight hours.
And that might be the most telling detail of all. Drivers are willing to adapt their behavior—timing stops, planning routes—if the incentive is strong enough. Cheap energy doesn’t just save money; it reshapes habits.
What makes ETC Solpark truly interesting isn’t just the price, but the replicability. This isn’t some exotic pilot project requiring government subsidies or cutting-edge tech. It’s solar panels, fast chargers, and a business model that prioritizes local energy use. In sunnier countries—southern Europe, anyone?—this approach could work even better.
In a landscape full of overpromised EV solutions, Katrineholm’s solar-powered fast charger stands out by doing something refreshingly radical: it works. Fast, cheap, clean—and no asterisks required.
