A study on the reliability and performance of solar powered street lighting systems

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.

The paper deals with an extensive photovoltaic (PV) modules monitoring activity carried out at the outdoor station ESTER (Solar Energy TEst and Research) of the University of Rome Tor Vergata, Italy. The purpose of the work was to evaluate and compare the performance of PV silicon modules of polycrystalline (poli-Si) and amorphous (a-Si) technologies during a medium-term outdoor exposure at optimized tilt angle, facing south. Two PV modules, one polycrystalline silicon and one double-junction amorphous silicon, have been exposed since May 2009 until Oct. 2010. A complete characterization of the weather conditions at the site during the test has been performed, and the most relevant parameters for the performance comparison of the two technologies have been derived. In order to compare different technologies and power productions, the energy yield (Y) and performance ratio (PR) for the two modules have been evaluated on a monthly and yearly basis. The typical seasonal trend of PR has been observed for the polycrystalline module, essentially due to the temperature influence on the module performance. For the a-Si module, instead, a degradation trend has been observed for the first months of operation. Subsequently, a significant recovery in the PR and energy production has been registered.

Performance Results

This manuscript reports the monitored performance results of roof top solar photovoltaic (PV) power plants in different parts of Tamilnadu, India. In this work, PV plants of capacities 84 kWp and 18 kWp located at Tirunelveli and Ranipet respectively in Tamilnadu are considered. During an eight month period, of September 2014 to April 2015, these plants had generated 43.99 MWh and 15.55 MWh units of electricity respectively. The average electricity production per day for the considered period of these plants is 181.74 kWh and 62.81 kWh respectively. The performance ratio (PR) of these plants PV1 and PV2 is found to be 0.52 and 0.86 respectively. The characteristics of poly crystalline PV modules and the performance of employed photovoltaic inverters are also analyzed.It is observed that external conditions like climate and bad weather significantly reduces the PV system output, whereas it reduces marginally due to inverter failure as observed from the values of energy yield and performance ratio of these plants. Online monitoring of PV plant with DC/AC line and phase voltages and current waveforms observed for the given day are also presented.

The Cost

The light emitting diode (LED) street lighting systems based on solar photovoltaic technology have been used for some time. In this paper, we present an analysis aiming at assessing the feasibility and economic performance of a solar-powered street lighting system for a 1km road. The present study introduces the architecture of a classical solar-powered LED street lighting system and estimates the total investment cost for a 1 km highway with 2 lanes. The cost comparison of solar-powered LED lighting and sodium lamps using grid was carried out. The calculations show that the energy saving effect of solar-powered LED lighting systems is obvious but the initial investment of solar-powered LED systems is more than sodium lighting systems using grid. The investment cycle is about 2.2 years under the current conditions.

In this paper, a performance evaluation technique using most frequent conditions (MFC) for accurate design of photovoltaic systems, based on energy rating and site-specific standards is reported. Most frequent conditions are estimated for the three different technologies: multicrystalline silicon (mc-Si), amorphous silicon (a-Si), and hetero-junction with intrinsic thin layer (HIT) for the site based on air-mass, module temperatures, incident in-plane irradiance, and power output. The performances are analyzed over a period of 3 years by evaluating changes in the performance ratio, the energy yields, and the percentages of occurrence of data points corresponding to standard test condition (STC), nominal operating cell temperature (NOCT), and MFC. For MFC, performance ratio (PR) values are ranging from 0.70 to 0.83, 0.70 to 0.86, and 0.70 to 0.90 for mc-Si, a-Si, and HIT, respectively. The total energy yield of HIT is the highest followed by a-Si and mc-Si modules for this climatic zone.

Advancement of technology brings advantages to human race to certain extent. Unfortunately, some of the technological inventions not only brings advantages, but also disadvantages. One of the disadvantages is the pollution of carbon emission in the environment from the non renewal energy resources. Therefore, to prevent pollution from getting worse, the environmental-friendly aspect is suggested to be included in new inventions nowadays. Thanks to the invention of solar panel, solar energy is able to become a renewable energy source that can be applied to various applications. Considering the increase of electricity consumption every year in Malaysia, solar powered street lighting system is proposed in order to reduce the burning of fossil fuels to generate electricity, hence reducing air pollution. The proposed street lighting is companied with automatic switching mechanism to further reduce the electricity consumption of street lights. The system will also be able to provide energy measurement to determine the efficiency of street light. Security features like motion detection and camera module interfaced to the street light for surveillance monitoring in a residential area to overcome intruders and crime such as theft. Theft is now major issue in Malaysia and in many developing and developed countries. The news reported that many people lost their belongings due snatch theft and averagely 16 people go missing every day. Overall design of the solar powered street lighting systems with the security features will help people live in green and protected environment. The implementations of client server connection and Remote Method Invocation (RMI) in wireless network system ease the monitoring process of the entire street lights in a residential area for giving continuous service to the community and environment.

High Pressure Sodium Lamp

Turkey is rich in terms of renewable energy sources and, therefore, is now encouraging the use of sustainable clean lighting systems in road applications. High pressure sodium lamp is the most widely used type in main roads, but other types of lamps such as mercury vapour lamps or metal halide lamps can be utilized for street lighting. Since it enables energy and money saving, LED light technology has replaced high pressure sodium lamps nowadays. Once solar power system (PV) is integrated with LED lamp for street lighting, the amount of saving and local impact might be enriched. LEDs used as light sources in road lighting luminaires with rising lumen values, decreasing junction temperature, higher colour rendering efficiency, longer lifetime have become more efficient than many light sources with the latest developments. Since the structure of the luminaires in which the LED light sources are used differs from that of the conventional light sources, the optical, thermal and electrical design of the LED luminaires must be considered differently. Thus, this study concentrates upon design considerations and the operating principle of solarpowered LED road lighting luminaire in details. Also, a simple solar panel system was designed and the economical values obtained at the end of 20 years were compared when using the ongrid system and the off-grid system.
