Comparing the Performance of Pivotless Tracking and Fixed-Type Floating Solar Power Systems

Floating solar power has a higher power generation efficiency than existing solar power generation methods. It is easier to secure in an installation area as well as to connect to other renewable energy sources. Floating solar power is considered an essential component for achieving carbon neutrality because it compensates for the shortcomings of existing solar power systems and maximizes their advantages. In this study, a performance comparison was conducted between pivotless tracking-type and fixed-type solar power systems. These systems were installed at the Irwol Reservoir in Suwon, South Korea, and monitored for comparison between May 2019 and June 2020. The tracking-type system generated approximately 14% more energy than the fixed-type system; the performance was maximized in May, which showed 25.63% more output power, and the performance was minimized in winter, with 3% more generated power. Owing to its pivotless structure, this system can be used in the solar industry.
