1080 solar panels, 640kW power generation, 3.4MWh energy storage capacity, all free!
Free charging has actually happened in California.
For electric vehicle owners driving long distances, the biggest fears are: arriving at a service area to find all the charging stations broken, long queues, or exorbitant electricity bills. But now, a startup in California has come up with a new solution-disconnecting the charging station from the grid, generating and storing its own electricity, making the entire station operate like an independent island.
How does a charging station without a grid connection survive?
This company, PowerStation, recently opened a brand-new fast-charging station near the Rasor Road exit on Interstate 15 in California. This location is in the desert, with abundant sunshine year-round.
The entire station uses 1080 solar panels, capable of generating up to 640kW of electricity. This electricity is stored in a 3.4MWh energy storage system, ensuring continued power supply even at night or on cloudy days. To illustrate, it's like a camel storing fat in its hump-it eats voraciously during the day and slowly burns it off when there's no sun.
Currently, the station has four CCS1 charging ports with a total power of 360kW. The company says they plan to install six more NACS ports this summer, increasing the total power to 600kW. If only one car is charging, it can utilize all the power; if multiple cars are charging simultaneously, the system will automatically distribute the power, ensuring everyone gets a share.
The best part is that you don't need to download any app or register a membership; you can simply plug it in to charge. And from now until May 31, 2026, it's all free. After the free period ends, the charging price will fluctuate based on the day's sunshine and electricity demand, approximately $0.30 to $0.45 per kilowatt-hour, which is about 2.1 to 3.1 yuan at the current exchange rate.
And that's not all; three more are planned.
PowerStation is also working on three similar solar fast-charging stations. One, located near Barstow along Highway 15, is scheduled to go into operation this year. The other two stations are located along Highway 10 and Highway 8, respectively, and are scheduled to open in 2027.

This approach isn't unique to PowerStation. Tesla also built a larger one last year in Lost Hills, California-it has 164 charging stations, an 11MW solar power system, and 10 Megapack energy storage batteries, with a total storage capacity of 39MWh. The solar panels also double as carports, providing both sun and rain protection. Tesla's project took less than eight months from groundbreaking to the first batch of charging stations going into operation.
Is kicking the power grid out of the group chat a good idea?
Frankly, this model is not just about saving money.
First, it can save money. Traditional charging stations need to connect to the power grid, involving various approvals, capacity expansion, and potentially several years, with considerable costs in between. The cost of solar panels and energy storage batteries is steadily decreasing-research institutions predict that the cost per kilowatt-hour for electrochemical energy storage may drop to around 0.20 to 0.35 yuan by 2030. Research from Tsinghua University also shows that in areas with abundant sunshine, the average cost per kilowatt-hour for "photovoltaics + energy storage" could drop to 0.45 yuan around 2026, and 0.3 yuan by 2030 is a major trend. California plans to add 11 GW of utility-scale solar power capacity by 2030-in short, generating electricity with sunlight is becoming more cost-effective than connecting to the grid.
Secondly, it saves time. Tesla representatives have stated that waiting for grid upgrades would mean charging stations wouldn't be operational during peak holiday periods. By building their own solar and energy storage systems, they control the construction timeline.
Thirdly, it solves a major problem-what about areas where the grid can't reach? Along highways in deserts, grid expansion is extremely expensive; laying a single power line could cost millions of dollars. This integrated photovoltaic (PV) and energy storage station functions like a giant power bank, operating independently without a power grid. For long-distance travel, it effectively fills the charging gap in remote, undeveloped areas.
From a manufacturing perspective: This is an industry chain.
From the perspective of advanced manufacturing, this charging station connects several links: PV panel manufacturing, energy storage battery production, DC fast charging equipment, and intelligent power dispatching systems. Behind each station lies a testament to manufacturing capabilities.
China has a strong industrial base in PV and lithium batteries, accounting for approximately 80% of global PV module production and over 70% of lithium battery production capacity. Similar projects are underway domestically-the Bazaar Zero-Carbon Service Area in Qinghai has built 27 charging spaces, and Ningxia's Huinong District has a demonstration station for "PV, energy storage, charging, and utilization." If the economics of combining PV and energy storage are sound, this model can be widely implemented.
The question remains: After the free period ends, do you think these charging stations can truly survive? Do you think a price of $0.30 to $0.45 per kilowatt-hour is expensive? Also, if these solar-powered charging stations were built along highways in China, which route would you most like to see them on?
