Summary: The study reveals that installing bifacial solar panels on a flat rooftop of industrial buildings can effectively increase yield, but changes in albedo due to soiling and moss growth make it difficult to accurately calculate power output. Experimentally, optimizing the layout of solar panels and selecting panels with higher bifaciality can increase yield.

Summary: The IEC 61853 standard series does not include bifacial PV modules, but their market share has significantly increased and is projected to grow. This work demonstrates how the standard can be extended to include the energy rating of bifacial modules, and provides a tested procedure for calculating rear irradiance and bifacial energy yield.

Summary: Outdoor photoluminescence imaging on field-deployed solar cell modules has been increasingly conducted in recent years. This imaging technique provides more detailed information about defects compared to thermal infrared imaging, and it has the potential to be faster than electroluminescence imaging as it does not require electrical connection to the modules. However, when conducted with sunlight excitation, it usually relies on lock-in technique, which involves switching between the modules' two operating points. This often requires additional electrical equipment and causes production disruption for the modules. This study demonstrates a noninvasive image acquisition method based on the string inverter's ability to sweep the IV curve. The advantage of this approach is that it only requires imaging apparatus and allows for flexible imaging procedures without additional equipment. Photoluminescence images spanning the whole IV curve can be obtained during one sweep, offering insights into the state of the cells and modules.

Summary: A new analytical model is proposed to simulate the performance of PV modules and module arrays over time. The model takes into account the performance loss due to module degradation and performance-reducing events. Experimental validation shows that the model accurately predicts the performance of various PV devices. The model can be used to evaluate the loss or gain of PV energy output and determine reliable performance-loss rates.

Summary: The study discusses the influence of PP-based backsheets on the performance and reliability of PV modules, with PP backsheets showing higher reflectance compared to PET backsheets and leading to increased power output. Test modules using PP backsheets exhibit higher corrosion resistance and no severe material degradation after extended exposure to temperature, humidity, and irradiation. PP backsheets have the potential to be a valid replacement for standard PET backsheets in PV modules, providing improved functional properties and long-term stability.

Summary: IEC 60891 ed.3, published in 2021, defines four standard I-V characteristics correction procedures numbered 1 through 4. The aim is to evaluate these four methods, and it is found that CP1 and CP2 work well over a broad range of irradiances and temperatures. However, CP1 requires accurate measurement of I-V curves at low-irradiance levels and CP2 is not suitable for low shunt-resistance modules. A new method based on CP2 is introduced to improve the performance for low shunt-resistance modules. CP3 works well but may cause distortion of corrected I-V curves during extrapolation. CP4 shows good results in I-SC but worse agreement in V-OC and P-MAX.

Summary: The energy-labeling scheme of the European Union is effective in communicating energy use of products to consumers and ensuring environmental friendliness of PV products. The proposed methodology uses estimated annual and lifetime yields of PV modules and systems as parameters for classification, aiming to support a potential energy-labeling scheme for EU policy implementing measures.

In LETID-sensitive modules, mean degradation is approximately 6% P-MP. LETID affects each cell in a module differently. Overall, this work has contributed to the development of a forthcoming standard for LETID testing.
