Summary: A three-year experiment in south-central Iran evaluated the performance of PV systems, showing significant differences in dust effects from year to year. The annual degradation rate of the PV module was lower than expected, and economic analysis demonstrated that investing in the PV industry can be profitable even without government support.

Summary: This study analyzed the degradation of 56 m-Si PV modules exposed outdoors for 22 years in Seville, Spain, with findings of severe browning, milky pattern, and oxidation of the metallization grid as the main defects. The degradation rate was 30.9%, primarily due to a loss in short-circuit current, with lesser impact on fill factor and open circuit voltage.

Summary: The study investigates the performance and reliability of multi-crystalline, mono-crystalline, and silicon heterojunction PV arrays in desert climate over a 5-year period. A drop in energy yield and visual defects were observed, leading to further analysis. Among different manufacturers, multi-crystalline silicon (Multi_A), (Multi_B), and (Multi_E) showed the lowest annual degradation rate below 1%/year, while multi-crystalline silicon (Multi_D) and mono-crystalline silicon (Mono_G) exhibited the highest PV module power degradation. Encapsulant yellowing, back sheet cracking, and cell cracking were prominent failure modes.

Summary: This study evaluates and compares the performance of monocrystalline, polycrystalline, and thin film PV modules in different climatic zones of India, finding that the electrical efficiency of the modules is mainly affected by peak temperatures. Despite hot climatic conditions, Bangalore has higher electrical energy yield per annum compared to Jodhpur. Additionally, semitransparent back cover plate is found to be more efficient than opaque back cover plate.

Summary: Photovoltaic systems may perform below expectations due to inaccurate estimates, suboptimal operations and maintenance, or component degradation. Accurate assessment of loss factors helps address underperformance and achieve accurate expectations and models. It is important to distinguish between recoverable and nonrecoverable losses underlying performance loss rate (PLR).
