DESIGN ANALYSIS OF SOLAR-ELECTRIC PROPULSION SYSTEM OF A TOUR BOAT
Keywords:
solar energy, propulsion systems, resistance, power, vessel speedAbstract
This project aims to develop a solar-powered propulsion system for tour boats by harnessing solar energy using strategically positioned photovoltaic (PV) panels and electric propulsion motors. An energy storage system with advanced batteries to store excess energy from the PV panels to enable continuous operation at sunset or on cloudy days was designed. Suitable PV panels for adequate power generation were chosen to match the energy requirements for propulsion system, navigational systems, and other services on board. Canonical equations were used to model the parameters for motor characteristics, vessel speed, resistance components, and power requirements. With a 0.3 kW/m2 output power density and 90 kW total power need, 300 m2 of solar panels was required. Consequently, 56 and 110 batteries for 24 and 48 hours, respectively, were needed when cruising at 18 knots with a total electric load of 50 kW. Implementing the research findings, recreation boats’ operators will be able to utilize the abundant solar energy, for environmentally conscious and sustainable marine transportation to ameliorate the hazards of fossil fuel-powered vessels.
