摘要： Disclosed is a method of controlling a cluster of solar trackers in which a plurality of solar trackers exist as a cluster shape. The method includes detecting, by each of the cluster of solar trackers, one or more of power generation amount information, altitude information, and azimuth information thereof and transmitting the detected power generation amount information, altitude information, or azimuth information to a server, calculating, by the server, average power generation amount information, average altitude information, or average azimuth information using the power generation amount information, altitude information, or azimuth information of each of the cluster of solar trackers, and determining whether the cluster of solar trackers is normal by comparing the calculated average power generation amount information, average altitude information, or average azimuth information with the power generation amount information, altitude information, or azimuth information detected by each of the cluster of solar trackers.

摘要： The sunlight sensing apparatus includes a sensor portion which includes a first sensor sensing sunlight in a first direction and a second sensor sensing the sunlight in a second direction for altitude adjustment and includes a third sensor sensing the sunlight in a third direction and a fourth sensor sensing the sunlight in a fourth direction for horizontal rotation, in which the first sensor, the second sensor, the third sensor, and the fourth sensor are formed of the solar cells, a power supply portion which charges sensor power formed at the first sensor, the second sensor, the third sensor, and the fourth sensor through a photoelectric effect caused by the sunlight, and a control portion which performs a control operation for transmitting sensing signals. Here, the control portion is driven by the sensor power charged by the power supply portion.
