Abstract

The increasing demand for food and the limited availability of agricultural area have driven the development of innovative cultivation systems such as hydroponics. The utilization of solar energy in agricultural systems offers an environmentally friendly and sustainable solution. This study aims to analyze the design of a deep water culture (DWC) or floating raft hydroponic system powered by renewable energy using a solar photovoltaic system for cultivating water spinach (Ipomoea reptans). The system was designed as off-grid configuration using 80 Wp photovoltaic (PV) panel, 100 W inverter, and 30 Ah/12 V VRLA battery. The analysis covered the energy demand of the venturi pump, local solar radiation potential, and the performance of the solar power system through simulations using the Global Solar Atlas and PVsyst software. Results showed that the average daily energy output of 289.33 Wh was sufficient to the system's electricity requirements, with an annual Performance Ratio (PR) of 60.1% and a Solar Fraction (SF) of 97.2%. The solar-powered system proved to be reliable, efficient, and stable in supporting year-round hydroponic operations, achieving a crop yield of 2.57 kg/m² per cycle. The integration of hydroponics and solar energy presents a sustainable agricultural solution that is both energy-efficient and environmentally friendly.
