Three vertical doppler rider WindCube V2.1 have been installed. One of them uses an independent power supply system that combines a PV panel and a fuel cell, which allows rider observation on a power supply site such as a mountainous area. In addition, the remote monitoring system of the independent power supply performs a 24 -hour monitoring of the amount of solar radiation and power generation, and can be restarted by remote control in the event of an abnormality and returned to normal operation.
