Abstract:
Long-term reliability assessment of solar photovoltaic (PV) modules is very important to ensure the economic viability of the PV system. A number of factors that affect the degree of useful effect, performance and lifetime causes degradation of solar PV modules. One of the main reasons that contribute to the decline of solar PV performance is the problem of aging, so accordingly, the main causes, shortcomings, problems and challenges that affect it are identified, addressed and investigated as part of research and commercial purposes. This paper analyzes many factors that affect degradation-aging of solar PV modules including: exposure to sunlight, temperature, moisture, dust, discoloration, cracks, and delamination. In addition, the effects of aging factors on solar PV modules performance are investigated, including lifetime, useful performance, material degradation, overheating, and misalignment from both visual and electrical characterization points of view. Degradation rates are determined by the ratio of module performance, temperature losses and energy yield, and visual inspection and electrical characterization are a fundamental part of the PV system evaluation process. Electrical characterization methodologies for measuring the degradation rate of PV technologies are listed, where the accuracy of each method depends on the measuring equipment, data qualifications and filtering criteria, metrics and statistical data calculation methods. Finally, directions for future research, best practices and recommendations for overcoming aging issues and achieving sustainable management and operation of solar energy systems are provided. For PV engineers, manufacturers and investors, the critical analysis, evaluation and research directions of this work can be very useful, because getting to know and conducting additional research and development on this aging issue would enable greater benefits with an increase in the lifespan of solar PV systems.
