Abstract: A system for street light lighting control and for Internet-of Things control for monitoring solar power generation includes a solar panel configured to generate photovoltaic-based electricity using sunlight; a battery configured to store the electricity generated by the solar panel; a solar controller configured to control the battery to store the electricity; and a street light controller configured to control lighting of at least one street light using the electricity stored in the battery, wherein the solar controller includes a battery information detection module configured to detect remaining charge information and discharging time information, which are charging/discharging status information of the battery and a communication module configured to transmit the remaining charge information and discharging time information to a monitoring server, wherein the communication module transmits the charging/discharging status information, the remaining charge information, and the discharging time information

Abstract: Disclosed is a gateway apparatus for photovoltaic power generation facilities. The gateway apparatus includes a first communication portion which performs short-range wireless communication with at least one of a photovoltaic module connection board, a photovoltaic inverter, a peripheral environment sensing apparatus, a power measuring apparatus, and an energy storage system (ESS), a second communication portion which performs wired communication or wireless communication with a remote server, and a control portion which controls operations of the first communication portion and the second communication portion. Here, the control portion controls information provided from one or more of the photovoltaic module connection board, the photovoltaic inverter, the peripheral environment sensing apparatus, and the power measuring apparatus to be transmitted to the ESS.

Abstract: 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.
