Sizing a solar cell array for a solar powered lawnmower machine

Abstract

This project focuses on the sizing and control of a photovoltaic (PV) collector of a solar lawnmower prototype to satisfy the geographical orientation of Puerto Rico and its available sunlight. The design, analysis and construction of a Solar Powered Lawnmower prototype were performed to obtain an electrical device powered by a renewable and ecology friendly source of energy. Photovoltaic technology reduces the use of fossil fuel and increases the safety of the mowing operation. Complete mathematical modeling and computer simulation of the components of the Solar Powered Lawnmower machine (power system, driving, photovoltaic modules, frame/chassis, steering system) was performed so as to have the lowest possible energy consumption, which at the same time would have a direct influence on the sizing of the photovoltaic cell arrays or PV collector. After completing the computer model of the proposed solar lawnmower, a prototype design was built and tested.
