Application of solar-powered signboard using LED light for commercialization

Abstract

This study presents the application of solar power signboard using LED light for commercialization which is an innovative design of signboard was proposed where the infrastructure equipped with lamps and electrical signboard powered by solar PV energy system. The new system was aimed to provide higher level human comfort as well as information to user, and the prototype was applied in School of Environmental Engineering, “Universiti Malaysia Perlis”. It alternatively evaluates the potential of solar-powered signboard using LED light with comparison to the existing conventional signboard using fluorescent lamp. 2 unit of solar panel 20 watt was connected to the battery and solar charge controller connected to the battery to avoid battery overload charge. The LED lights were installed in the signboard designed. The objectives in this study, to evaluate the potential of LED light and to formulate a signboard configurations using solar powered and LED. The period of time the lighting at night was recorded by observation to consider the battery capacity which is at least lighten at night for 4 to 8 hours. The initial cost for solar-powered system LED light was higher than the existing conventional signboard system fluorescent lamp. The observation was made that operating cost is depending to the sources of the installation which is for solar-powered signboard using LED light was directly used the energy from the sun so it had free for operating cost. Use solar energy and efficient lighting system saved 50% amounts of energy, zero in operating cost, and also indirectly reducing emission 142.96 kg of carbon dioxide.
