| Summary: | The demand to seek new renewable energy sources for electricity has been rising. Therefore, solar street lighting system is an effective way to reduce power consumption and CO2 impact on the environment with the maintenance of the safety standards of the road. Roads are significant facilities of local municipalities and their lighting systems. Most conventional street lighting systems are turned on/off regularly. The result is that if there is low road traffic, a large part of electricity consumed by street lighting will be wasted. Automated street lighting system attracts a lot of worldwide interest due to the growing demand for global energy use and the green environment. In this research, a cost effective and energy efficient automated street light control based on PIR motion sensor and timer is proposed. The streetlight is automatically controlled with the motion the road pedestrian near to the streetlight. This system uses photovoltaic (PV) as main supply, battery as storage supply and fuel cell (FC) as backup supply. In lighting side, Light Emitting Diode (LED) is used and dimmed with control by relay. The design uses 250W solar panel with 8A x 31.25V (200Ah) battery. The system has the design capability to last for 12 hours per day and controlled by timer. The method using is by calculate and compute the load profile (LED bulb used), hours of usage, Ah for battery storage, sizing solar panel charger controller rating will be analyzed to optimized usage in solar LED streetlight system. Furthermore, the total consumption of streetlight solar system will be analyzed and show by graph. Hence the loss of energy due to unnecessary glow of the streetlights can be avoided and it will bring considerable economic benefits. Solar LED Streetlight system thus reducing the cost further, and a more energy-efficient system are achieved. An economic analysis is also performed to determine the cost effectiveness of the cost installation is found to be RM 1896.00 for 1 pole streetlight comparing the conventional streetlight is found RM 2650.00 which is equivalent to 39.77%. Proposed system can be saving energy consumption 1200W for 1 pole within 12 hours per day. |
