The PV power generation system is a comprehensive system that transmits the power generated through a PV panel to a grid

connection and is composed of a solar panel, a structure, and an inverter grid connection system. One technology to increase the

amount of power generated involves changing the incident angle of sunlight. This study examined the structure and control of a

single-axis tracking PV system that increases the amount of power generated by changing the incident angle. The core content is a

single-axis control system and technology configured to rotate the solar structure in the east-west direction around the north-south

axis. A solar structure that follows the sun from sunrise to sunset in the east-west direction needs to secure structural stability and

solar tracking control performance. A single-axis tracking system can generate up to 25% more power.
