Abstract
Outdoor lighting represents 10-20% of the electricity used in majority of the countries. However, electricity utilized by street lights is predominantly generated from fossil fuels and has negative impact on the environment. Globally, researchers are looking for efficient technologies that are eco-friendly and cost-effective. Over the past decade, Solar Photovoltaic (PV) technology has shown exponential progress in terms of efficiency and lower cost. Our research is focused on providing sustainable options for outdoor lighting by installing solar-based smart lighting system. In addition, this research also helps NKU to achieve carbon neutrality goal by 2050. Four existing light bollards around Lake Loch Norse are used as test beds for this project. Solar panel is installed at a fixed angle for the first test bed. For the second test bed, a single axis tracking system for solar panels will be installed. This system tracks the sun from east to west thereby increasing the efficiency of the solar panel. The third test bed will use a dual axis tracking system that follows the sun position with seasonal changes. Lastly, fourth test bed will be placed in shade. All test beds are programmed using an Arduino and sensors such as Light sensor (LDR), Motion sensor (PIR), and a real time clock (RTC) are used. Moreover, data obtained from voltage and current sensors will be sent over wifi module to a server for comparison of test beds. Cost and efficiency of each test bed will be compared and analyzed. Currently, the first bed is installed and second bed is underway.
