Special Issue Information

Dear Colleagues,

Over the recent decade, the global installation capacity of photovoltaic (PV) systems has skyrocketed. By the estimation of the International Energy Agency Photovoltaic Power Systems Programme (IEA PVPS), the global installed PV capacity could have hit 260 GW in 2022. With such huge installation capacity, the operation of PV systems with high degrees of efficiency, reliability, and safety is more significant than ever. Nevertheless, the PV modules are installed in complicated outdoor conditions, suffering from the harsh exposure, daily thermal cycle, moisture invasion, etc. The performance analysis became a popular method for evaluating the health status of PV systems.

This Special Issue aims to collect and summarize a comprehensive advanced technology related to the performance analysis, condition monitoring, fault diagnosis, remaining useful life prediction, and maintenance of PV systems. 

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following areas:

  • Performance analysis of photovoltaic system based on meteorological and electrical big data;
  • Advanced condition monitoring system or platform for photovoltaic systems;
  • Data cleaning and management of photovoltaic system for performance analysis;
  • Modeling and simulation of photovoltaic system with faults or abnormalities;
  • Fault diagnosis of photovoltaic system based on electrical data or site images (visible light or thermal images);
  • Module-level fault localization of photovoltaic system;
  • Outdoor degradation mechanism of photovoltaic modules;
  • Remaining useful life prediction of photovoltaic system;
  • Advanced robotic maintenance technology of photovoltaic systems;
  • Optimization of maintenance schedule for photovoltaic systems.

We look forward to receiving your contributions.

As the global emphasis on solar energy intensifies, optimizing the efficiency of photovoltaic panels becomes crucial in meeting energy demands sustainably. Addressing this, our research delves deeply into advancing maximum power point tracking (MPPT), a pivotal component in perfecting the energy conversion process. Leveraging state-of-the-art mathematical modeling, in-depth simulations, and comprehensive experimental validation, we set out to markedly refine the performance of non-isolated multi-branch buck DC–DC converters. In this pursuit, we introduce an innovative algorithm meticulously designed to adjust the number of active branches. This adjustment is rooted in robust efficiency metrics, ensuring optimal power delivery even under dynamic and fluctuating conditions. We place a distinct emphasis on the transformative role of current in determining converter efficiency. Drawing from our findings, we advocate for an adaptive control strategy, precisely engineered to thrive in a spectrum of operational contexts. With this study, we not only present pivotal contributions to the domain of photovoltaic technology but also chart out clear expectations for future endeavors. Our hope is that these advancements serve as foundational steps, guiding the evolution of sustainable energy generation. Full article

The performance and reliability of photovoltaic (PV) modules in a desert climate depends, among other factors, on the solar irradiance, operating temperature, and soiling rate. Since the impacts of these environmental factors depend on the type of PV module technology, an assessment of the PV technology to be deployed in the desert climate is crucial for the bankability of PV projects. In this work, the indoor and outdoor performance of monofacial and bifacial silicon heterojunction PV module technologies were assessed. For the indoor measurements, a comparison of the current-voltage (IV) characteristics was performed at standard testing condition and at different temperatures. The two module technologies showed similar temperature coefficients and expected performance within the measurement uncertainty. Comparing the specific energy yield of the modules installed in the Outdoor Test Facility (OTF), the bifacial module showed a 15% higher energy yield than the monofacial module and is attributed to the contribution of the bifacial rear side, thanks to the reflected irradiance received by the bifacial module and the high albedo of 0.43 measured at the OTF. Moreover, the bifacial module was found to be less sensitive to the PV soiling than the monofacial module. The results showed that the frequency of module cleaning could be reduced for the bifacial module compared with the monofacial module, resulting in a remarkable decrease in the module cleaning cost and PV site Operation and Maintenance cost.
