Advances in solar photovoltaic tracking systems: A review

Abstract: Solar photovoltaic technology is one of the most important resources of renewable energy. However, the current solar photovoltaic systems have significant drawbacks, such as high costs compared to fossil fuel energy resources, low efficiency, and intermittency. Capturing maximum energy from the sun by using photovoltaic systems is challenging. Several factors that affect the energy output of such systems include the photovoltaic material, geographical location of solar irradiances, ambient temperature and weather, angle of sun incidence, and orientation of the panel. This study reviews the principles and mechanisms of photovoltaic tracking systems to determine the best panel orientation. The tracking techniques, efficiency, performance, advantages, and disadvantages of simple tracking systems are compared with those of state-of-the-art tracking systems. Diverse types of solar tracking systems based on their technologies and driving methods will be presented and categorized.The future trends of tracking systems are also highlighted.

Satisfaction and trust on customer loyalty: a PLS approach

Abstract: Purpose – The purpose of this paper is to test some antecedents and outcomes of satisfaction in the banking sector in Malaysia.Design/methodology/approach – A research model based on the customer satisfaction index (CSI) was developed and tested using structural equation modeling technique with the use of partial least squares (PLS) approach. Data was analyzed using 239 bank customer responses.Findings – The results showed that satisfaction has a positive effect on trust and this trust leads to loyalty to the bank. Good complaint handling by banks will also elevate satisfaction, trust and loyalty.Research limitations/implications – This work contributes to the existing literature on CSI models by introducing customer satisfaction as an antecedent of trust. The findings are limited by the constraints of the number of measures and the participation of banks in this study.Practical implications – Banks should focus on building credibility trust and benevolence trust with their customers.
