What you see is the Solar Power Generation, Solar Concentrator System.
The solar cell that takes up the largest part on top is a fixed module.
It converts the energy of light directly into electricity by causing the photovoltaic effect which is the generation of voltage and electric current in a material upon exposure to light.
The solar cell is installed at tilt angle of 33 degrees facing south which is the most efficient angle for Korea’s latitude.
The nine solar cells that you can see in the bottom is a tracking module that tracks the sun with GPS system to generate energy.
The fixed type has low generation efficiency over the module installation while the tracking type has higher generation efficiency.
The cylindrical shape is the solar concentrator system.
While the solar cell generated electric energy, the solar heat heats water.
Solar energy is converted into heat energy at collector element and the heat energy is stored at thermal storage element, making hot water available for use at all times.
The light duct and the optical fiber are on the right.
As the solar photovoltaic power from the light duct and the optical fiber is supplied to the inside of the building and parking lot, the energy consumption during the daylight can be reduced.
