“…The heliostat shape however should additionally consider wind loads and turbulence to drop the cost below 100 $/m 2 [60]. Furthermore, mirror soiling, erosion, aging and degradation [1] are further points for consideration affecting the annual performance of CSP plants. Methods integrating ray tracing and for on site characterization [61,62] and misalignment have been reported [56].…”

“…HSPs, being inherently stable at high temperatures (silica melting point ≈ 1710 • C), are good candidates for high temperature thermal insulation applications (e.g., insulation of concentrated solar power storage tanks and pipes [85], high-temperature fuel cells [86], where conventional insulation materials based on foams or cellulose fibers are not suitable. Polymer and carbon hollow particles can also be used for thermal insulation applications [11,14].…”

Hollow silica particles (or mesoporous hollow silica particles) are sought after for applications across several fields, including drug delivery, battery anodes, catalysis, thermal insulation, and functional coatings. Significant progress has been made in hollow silica particle synthesis and several new methods are being explored to use these particles in real-world applications. This review article presents a brief and critical discussion of synthesis strategies, characterization techniques, and current and possible future applications of these particles.

“…Therefore, these kinds of faults can occur on both DC and AC sides. PV module defects for instance delamination, yellowing, and browning of solar cells, cracks, gaps, bubbles, and defects in the anti-reflective coating are examples of DC-side incipient faults [7]. Wiring degradation, Insulated Gate Bipolar Transistor (IGBT) faults, islanding, overheating, and aging are all AC-side faults.…”

In this work, an effective Fault Detection and Diagnosis (FDD) strategy designed to increase the performance and accuracy of fault diagnosis in grid-connected photovoltaic (GCPV) systems is developed. The evolved approach is threefold: first, a pre-processing of the training dataset is applied using a multiscale scheme that decomposes the data at multiple scales using high-pass/low-pass filters to separate the noise from the informative attributes and prevent the stochastic samples. Second, a principal component analysis (PCA) technique is applied to the newly obtained data to select, extract, and preserve only the more relevant, informative, and uncorrelated attributes; and finally, to distinguish between the diverse conditions, the extracted attributes are utilized to train the NNs classifiers. In this study, an effort is made to take into consideration all potential and frequent faults that might occur in PV systems. Thus, twenty-one faulty scenarios (line-to-line, line-to-ground, connectivity faults, and faults that can affect the normal operation of the bay-pass diodes) have been introduced and treated at different levels and locations; each scenario comprises various and diverse conditions, including the occurrence of simple faults in the PV1 array, simple faults in the PV2 array, multiple faults in PV1, multiple faults in PV2, and mixed faults in both PV arrays, in order to ensure a complete and global analysis, thereby reducing the loss of generated energy and maintaining the reliability and efficiency of such systems. The obtained outcomes demonstrate that the proposed approach not only achieves good accuracies but also reduces runtimes during the diagnosis process by avoiding noisy and stochastic data, thereby removing irrelevant and correlated samples from the original dataset.
