“…The installation cost of just one or two utility power poles can justify the initial cost of a PV lighting system [20]. However, a general observation from prior reports has shown that many PV streets lighting systems have experienced a number of component failures, including premature charge controller, battery, and ballast illumination failures [41], [44][45]. This is as a result of some identified factors/challenges that are discussed in detail in Refs.…”

“…The complete street lighting system can run on a highly efficient PV system to reduce power consumption [42]. As a result, PV lighting systems for cities and towns now represents one of the largest cost effective markets for PV [41][42][43]. The installation cost of just one or two utility power poles can justify the initial cost of a PV lighting system [20].…”

“…Some authors studied the long-term outdoor performance, degradation and failure of PV systems/modules across the world [18], [22], [35][36][37][38], [40] while other explored the short-term effects (infant-failures) of these systems [33,39]. Yet, only few reports on the degradation rates and failure mode of PV Street lighting systems (a major outdoor lighting system for roadways and streets [41][42][43].) have been presented in the literature [17].…”

This paper presents the results of a study on the reliability and performance of the solar-powered street lighting systems installed at the African University of Science and Technology (AUST) in Nigeria, a hot and humid environment. The technical performance of the systems was studied using the following performance indicators: system energy yield, capture loss, as well as the system performance ratio while the reliability of the systems was examined using a model developed from the findings from the maintenance and fault diagnosis of the systems. The model was used to predict the total failure and survival probability of the systems using the Weibull distribution. The performance evaluation during the monitored period (February 2012 to January 2015) indicated that the performance ratios of the systems vary from 70% to 89% and the energy yields of the systems ranging from 2.87 h/day to 5.57 h/day. The results from the reliability analysis also showed that when the stress concentration factor around the notch between the cable terminals in the charge controller increases, the charge controller will become overheated, which in turn affected other components of the systems. The implications of this study are also discussed for the design and development of future solar-powered street lighting systems.

Abstract-High-intensity discharge (HID) lamps are becoming popular substitutes for halogen lamps in automotive headlamps because of the high lumen/watt ratio and the color of the light. In this paper, a ballast (integrated with a voltage multiplier circuit in the secondary winding of the dc converter transformer) with dimming control is presented. The proposed circuit not only eliminates one auxiliary winding but also reduces the voltage across the switch on the primary side and consequently permits the selection of switches with a lower rating. A brief review of the HID circuits is done and compared with the proposed circuit. Experimental results from the prototype are presented. This paper also presents different methods of dimming the automotive HID lamps based on analog and digital control and discusses the relative merits of each of the methods. The dimming control is implemented using both the methods, and experimental results are presented. It is envisaged that the dimming control will provide some flexibility to drivers in the control of HID lamps to suit the driving conditions in the modern cities that are very well lit at night. This paper investigates the merits of each method and discusses the practical issues for implementing such controls.Index Terms-Constant power, dimming control, highintensity discharge (HID) ballast.
