A Proposed Standard Design of Solar Street Light System Towards Energy Efficiency Development for Managing Facility Planning

摘要

This research paper is to explain a proposed Solar Street Light (SSL) design towards energy efficiency development for managing facility planning. Street lighting is an indispensable public service that provides a safer environment at night time to commuters as well as pedestrians. However, the Conventional Street Light (CSL) is not without some challenges, such as high energy consumption and cases of electrocution. Therefore, in light of the problems, this research is aimed at developing a new framework for producing a modern design of SSL. Some of the significant technical requirements and procedures for the development were discussed, which is comprised of LED street lamp chip, lamppost, solar panel, battery and controller. Also, a detailed comparison between the two types of street lighting was explored in the study - that SSL has the potentials of saving 64.7% of total cost compared to CSL. Some of the significant benefits of SSL are self-generation of power, which save energy thereby controlling issues related to environmental pollution. One of the uniqueness of SSL is its DC 12V working voltage, stability as well as human safety, as there are zero electrocution possibilities. This study thus proposed a framework of the 30m separation distance between street light poles, 9m height, light control system, 90W LED lamp, 5.4kWh volume of rechargeable battery, and 2 square feet of solar panel.
