Abstract There is significant domestic and international interest in the development of solar energy technology, particularly offshore solar technology, to overcome limitations in suitable installation sites. In marine solar technology, the structural integrity of the floating body is crucial for ensuring the safety of solar panels, in contrast to land-based solar systems. However, polyethylene (PE)-based floating bodies are susceptible to durability degradation from UV radiation and fatigue failure. Therefore, this work investigated a concrete floating body made of concrete that provides excellent durability, fire resistance, and ensures safety while floating. To achieve this, a comparative analysis of hydraulic model experiments and ANSYS AQWA simulations was conducted. The structural behavior of the concrete floating body under wave load conditions was evaluated by applying the validated analysis method to AQWA-structural coupled analysis of the actual structure.
