Wybrane pełne teksty z tego czasopisma
Purpose: The aim of the paper is to determinate basic parameters for components of demonstrative system which is traffic light pedestrian crossing. Design/methodology/approach: Photovoltaic module was produced from monocrystalline silicon solar cells which were joined in series. Photovoltaic system consists of solar module, astable generator, step-down converter and battery pack. Findings: It`s necessary to protect photovoltaic system from external factor like unstable light conditions, variable input voltage, shading. Taking this fact into account photovoltaic system with step-down converter was designed. Step-down converter adjust the voltage of photovoltaic module to the voltage of battery protecting them from overcharging and discharging. Research limitations/implications: The main goal of this work is to show the practical use of widely available, renewable energy source, which is the Sun through the selection of component for the demonstrative photovoltaic system -traffic light pedestrian crossing. Practical implications: In order to provide access to electricity in areas with limited access to power network, there irreplaceable are stand-alone photovoltaic systems, which can supply both AC and DC devices. Originality/value: The produced photovoltaic system confirms the usefulness of solar energy in every place where sunlight is available. In order to provide steady supply at night and in low sunlight the battery stores energy was applied.
