The solar-powered underground railway system, which runs mainly underground, seems to have no connection with solar energy, but the 108-station, 64-mile (102-kilometer) Metro system in San Diego, Chile's capital, is about to become the world's first solar-powered railway
.
Chile is one of the sunniest places in the world, and Metro will get 100 megawatts of electricity through the Atacama Desert, 640 kilometers from San Diego
.
If all goes well, next year's electricity production will reach 60 percent of the target, serving
the railway's 2.
5 million passengers.
Wind farms near the railway will also provide 18% of the necessary electricity
.
Metro is working with SunPower in the United States on this project, and the hardware mainly uses the latter's low-cost modular panels, which can greatly reduce assembly and maintenance costs
.
In particular, the transmission network will not fall into the general transmission grid, but will be transmitted directly to the railway system
.
And because the farm is located in the desert, SunPower also uses specially designed robots to clean
the panels.
Compared to SunPower's plan to provide renewable energy for electric vehicles, it seems to work better to bring green elements to mass transportation systems that require more electricity
