The paper presents an experimental energy and safety assessments of a 2.5 MWp capacity grid-tied solar photovoltaic power plant having installed at Pune, India.. The comprehensive step-by-step assessments of visual inspection, field testing, and evaluation of reasons contributing to different energy losses, precisely the effect of soiling has been made. The field testing include in detail the testing of solar photovoltaic strings and String Combiner Box (SCB), which encompasses tests of open circuit voltage, short circuit current, earth continuity, insulation resistance, and pull-out and contact resistance test for PV plug connectors to check the efficacy of plant components and the faults in the system. The string, SCB, and inverter operational voltage, current, and power are measured and analyzed. Thermal imaging of solar photovoltaic modules and sub-components based on temperature variance gauges the faults and losses in the plant are carried out. It is found that the effect of soiling on the system's overall health and energy perspective using term Soiling Ratio approach for cleaning plants rather than a fixed cleaning cycle on power plant plant performance and efficiency. It is concluded that the research findings helpful for further research on effect of soiling ratio of existing plant.

Long‐term reliability assessment of photovoltaic (PV) modules is key to ensuring the economic viability of PV systems. This paper presents a multi‐pronged performance degradation analysis of a 62.1 kWp solar PV power plant after 9.5 years of operation. For this purpose, various diagnosis techniques, namely, visual inspection, infrared thermography (IR), ultraviolet fluorescence (UVFL) and current‐voltage (I‐V) characterization, have been performed to evaluate the performance and degradation of the solar PV power plant. The visual characterization results show that the PV strings are affected by different mechanisms with different degrees of occurrences. The degradation mechanisms observed and the level of occurrence among the modules were found to be, encapsulant discolouration (100%), degraded frame adhesive (57%), degraded junction box adhesive (39%), snail trails (30%), burn marks (3%), cell cracks (2%) and delamination (0.4%). Although discolouration of the encapsulant was the most common possible degradation mechanism observed, the main causes of the power loss were snail trails and cracks in the PV cells. Furthermore, the IR thermography and UVFL analysis provided better understanding on snail trails phenomenon and crack mechanism on the affected PV modules. Besides imaging techniques, to assess the electrical performance of the system, we performed current‐voltage (I‐V) and power‐voltage (P‐V) characterization of the entire PV plant from which the degradation rates of the electrical parameters were determined. Our results show that the degradation rates for the maximum power and the fill factor are 0.84%/year and 0.66%/year, respectively, over the operating period of the installation. The estimated maximum power degradation rate for this installation could be considered as a realistic degradation rate for PV modules installed in harsh and hot desert climatic conditions. Additionally, our work has raised doubts about the validity of the warranties proposed by the manufacturers.

[6] Tantangan baru muncul dalam meningkatnya pemanfaatan PLTS yaitu menjaga unjuk kerja sistem PLTS tersebut, hal ini dikarenakan sama seperti sistem pada umumnya PLTS juga memiliki lifetime dalam beroperasi dan pasti mengalami degradasi setiap tahunnya [7], Oleh karena itu perawatan sistem PLTS merupakan sebuah hal yang penting untuk diperhatikan [8]. Pada Penelitian ini dilakukan Analisis terhadap unjuk kerja PLTS Carport 37,8kWp yang berada di area perkantoran Kementerian Energi Dan Sumber Daya Mineral Republik Indonesia di Jakarta Pusat.…”

The utilization of PV in Indonesia increased significantly. Based on data submitted by the Director General of EBTKE, the PV capacity value until first semester of 2021 is 217 MW. New challenge has emerged, namely maintaining performance of the PV system in good condition. Performance of the PV Carport system is analyzed by simulating PV using PVSyst software to see the potential value of electricity production, then calculating the performance parameters of the PV system such as Yield Factor (Yf), Yield Reference (Yr), Performance Ratio (PR) and Capacity Factor (CUF). Then compared with the results of electricity production and performance parameters of the PV system during operation for one year. The object of research on performance of the 37.8 kWp Carport PV system belonging to Ministry of Energy and Mineral Resources. Based on the PVSyst simulation results, the potential annual electrical energy from the Carport PV system is 53,910 kWh with performance parameters (Yf, Yr, PR, and CUF) respectively 1,426.19 kWh/kWp, 1,751.9 kWh/kW, 81.4% and 16%. The production value of the Carport PV system for a year in 2021 is 21,694.67 kWh with performance parameters (Yf, Yr, PR, and CUF) respectively of 573 kWh /kWp, 1,679.9 kWh/kW, 34% and 6.6%.
