Argentina has recently unveiled its first solar highway, the Circunvalación Avenue in San Juan, featuring 36 solar panel arrays with a capacity of 5 kW each. These panels are mounted on monopoles along the road and combined with inverters and LED lights to independently power the highway's nighttime lighting. The project, which created over 80 jobs during construction, is based on a distributed generation model used in other countries. San Juan's high solar radiation conditions enable the maximization of the capacity factor of the installed equipment, showcasing the potential for solar energy solutions in the region.
