Floating Solar PV Array Design for Water–Energy Integration at Kun Chaung Dam

This paper presents the design and performance analysis of floating solar photovoltaic (PV) system on the Kun Chaung Dam, located in the Bago Region of Myanmar. The study emphasizes the role of floating PV technology in advancing water–energy integration by utilizing existing water surfaces for clean energy generation while supporting water resource management. Comprehensive calculations and simulations were conducted, including PV array sizing, inverter and charge controller selection, and cell temperature estimation for both floating and land-based configurations. The P–V and V–I characteristic curves of the selected PV modules were analyzed under varying temperature and irradiance conditions to assess system behavior and efficiency. Technical, environmental, and economic factors were collectively evaluated to ensure feasibility and sustainability of the proposed system. Results indicate that the floating PV design at Kun Chaung Dam achieves higher energy yield and improved cooling performance compared to conventional ground-mounted systems, demonstrating its potential as an effective solution for integrated water–energy resource development.
