Abstract

Floating solar photovoltaic (FSPV) systems offer promising benefits, but there is limited research on their techno-economic and temperature impacts, especially in temperate regions of India. This study evaluates the feasibility of FSPV system in DAL Lake Kashmir, using the System Advisor Model (SAM). The technical assessment focuses on how temperature variations affect the performance of PV panels. Economic viability is analyzed through key metrics, including net present value (NPV), levelized cost of energy (LCOE), and payback period. The energy output of an FSPV system is compared to a land-based photovoltaic (LBPV) system with a similar 100 kWp capacity. The results show that the FSPV system with a 5° tilt enhances energy production to 0.14 GWh annually, surpassing the 0.1 GWh produced by the LBPV system. This leads to a 4.7% increase in capacity factor for the FSPV system. Furthermore, each 4 °C rise in module temperature results in a 1 MWh reduction in annual output and a 5 kWh/kW decrease in energy yield for both systems. The FSPV system also demonstrates a quicker payback period of 4.7 years, compared to 6 years for the LBPV system. These findings highlight the technical and economic viability of FSPV systems in India’s temperate regions.
