Summary: This article investigates the influence of the lifespan of a PV cooler on the performance of the product and proposes a new terminology called the PV cooler lifespan effectiveness factor to classify the lifespan effectiveness of PV coolers. The results show a proportional relationship between the lifespan of the PV cooler and the new factor, and an inverse proportional correlation between the lifespan of the PV and the new factor. This study has the potential to be helpful for PV cooler researchers, designers, and manufacturers.

Summary: This paper proposes progressive cooling and anti-reflection coating techniques for silicon photovoltaic modules. The ARC techniques involve the use of sol-gel-based-silica nanoparticles and polymethyl methacrylate polymer on the front of the glass and the silicon solar cell, respectively. The ARCs significantly enhance the output power of the conventional and lightweight PV modules. Furthermore, optimizing the water jet cooling system at the rear of the PV module further reduces the operating temperature and boosts the output power. Evaluation using the PVsyst modelling program shows a high potential for improving the performance of the PV module and system.

Summary: This article proposes a lightweight MMC-based grid-connected energy router (MGER) that integrates large-scale photovoltaic (PV) and centralized energy storage (ES) to eliminate power mismatches between legs and arms. The MGER uses four-terminal dual-active-bridges (FDAB) to connect horizontal three SMs, ensuring power balance and eliminating second-order circulating currents.

Summary: It has been discovered that a decrease in shunt resistance can result in the degradation and failure of solar modules over time. This paper presents a method to identify degradation before it becomes critical by analyzing the effects of reduced shunt resistance on the current-voltage characteristics of a PV cell. By artificially lowering the shunt resistance of five commercial polycrystalline solar cell samples and measuring their I-V characteristics, the impact on maximum power output, short-circuit current, open-circuit voltage, and fill factor was analyzed. Linear models were developed to establish the relationship between reduction in shunt resistance and Pmax and VOC. These findings propose that these relationships can serve as strong predictors and observers of shunt resistance degradation and can be implemented in online monitoring systems for operational PV modules.

Summary: This research presents a data-driven machine learning tool based on artificial neural networks (ANNs) that can forecast yearly photovoltaic (PV) electricity directly at the optimal PV inclination angle without geographic restrictions and is valid for a wide range of electrical characteristics of PV modules. Additionally, empirical correlations were developed to easily determine the optimal PV inclination angle worldwide. The ANN-based machine learning tool demonstrates high reliability and accuracy in the PV energy production forecasting for all weather conditions and PV module characteristics.
