商品簡介
This book introduces a study on using solar energy instead of fossil fuel energy to light the dark and gloomy streets. An intelligent smart street light system is implemented and the feasibility of SSL is evaluated using a case study of a remotely street located Real Estate Developer of Cairo University in Bolak Al Dakrour district in Giza, Egypt. The main objective is to investigate the technical design feasibility of standalone solar systems, to evaluate cost-benefit analysis of solar LED luminaries compared to convention electrical luminaries for the outdoor street lighting system and to determine the sizing of system components as well as simulation of lighting arrangements is performed using DIALUX 4.12 software package. Results show that the integrated solar street light including motion sensor is used here in this study including LAMP of 15 W LED PHILIPS, 45W Monocrystalline panel, 12 V 37.5 AH Lithium-ion battery, and 10 A 12 V charge controller. This proposed system is designed according to 12 operation hours: 4 hrs with 100% efficiency, 4 hrs 75% efficiency and 4 hrs with 50 % efficiency.
