Design and Performance Analysis of Integrated Floating PV System for Retrofitting the Kun Chaung Hydropower Plant

This paper presents the design and performance analysis of a 30 MW floating solar photovoltaic (FPV) system integrated with the Kun Chaung Hydropower Plant in Myanmar. The study involves a systematic approach covering site data collection and assessment, PV system design and array configuration, floating platform and mooring/anchoring design, electrical system design, shading analysis, and energy yield estimation and integration. Analytical calculations based on site-specific solar and environmental data were performed to determine system performance. Results show that the integrated FPV–hydropower system achieves an annual energy generation of 687 GWh, compared to 300 GWh from FPV alone. The hybrid configuration enhances power generation by reducing water evaporation and improving hydropower efficiency. The findings confirm that FPV–hydro integration offers a reliable, sustainable, and land-efficient solution for renewable energy expansion in Myanmar.
