Life cycle metrics evolution specific to the climate zone of photovoltaic (PV) operation would give detailed insights on the environmental and economic performance. At present, vast literature is available on the PV life cycle metrics where only the output energies ignoring the degradation rate (DR) influence. In this study, the environ-economic analysis of three PV technologies, namely, multi-crystalline silicon (mc-Si), amorphous silicon (a-Si) and hetero-junction with an intrinsic thin layer (HIT) have been carried out in identical environmental conditions. The energy performance parameters and the DR rate of three PV technologies are evaluated based on the monitored real time data from the installation site in hot semi-arid climates. The assessment demonstrates that the HIT PV module technology exhibits more suitable results compared to mc-Si and a-Si PV systems in hot semi-arid climatic conditions of India. Moreover, energy metrices which includes energy payback time (EPBT), energy production factor (EPF) and life cycle conversion efficiency (LCCE) of the HIT technologies are found to be 1.0, 24.93 and 0.15 years, respectively. HIT PV system has higher potential to mitigate the CO2 and carbon credit earned compared to mc-Si and a-Si PV system under hot semi-arid climate. However, the annualized uniform cost (UAC) for mc-Si (3.60 Rs/kWh) and a-Si (3.40 Rs/kWh) are more admissible in relation to the HIT (6.63 Rs/kWh) PV module type. We conclude that the approach of considering DR influenced life cycle metrics over the traditional approach can support to identify suitable locations for specific PV technology.

Investigation effects of environmental and operating factors on PV panel efficiency using by multivariate linear regression

The aim of this study is to show the investigation effects of environmental and operating factors on photovoltaic (PV) panel efficiency using by multivariate linear regression. Also in this study, the relationship between PV panel efficiency and some environmental and operating factors (solar radiation, opencircuit voltage, short circuit current (I sc), power, fill factor, outside temperature, humidity, wind speed, and voltage) were investigated using multivariate linear regression. The effect of binary parameter interactions on panel performance was investigated using the backward elimination (or deletion) method. The data used in the analysis were obtained from monocrystal and polycrystal panels in December in the winter season. In all analyzes, the regression values are close to 1, which indicates that the compatibility between binary parameters and performance characteristics is perfect. In addition, the three most effective parameters on panel efficiency were found to be solar radiation, maximum power (P max), and I sc , respectively.

Correction of PV modules' current-voltage characteristics (I-V curves) is essential before they can be used for performance analysis and fault diagnosis under real-life conditions. IEC 60891 (version 2021) has updated Procedure 2 and proposed a new correction Procedure 4 compared to the 2009 version. This study aims to analyze the performance of these new procedures applied to I-V curves of faulty PV modules. The work is based on an mc-Si PV module considering healthy and four common fault conditions with varying fault severity. The irradiance and temperature measured in the field are used to generate I-V curves. The correction procedures of IEC 60891 (version 2021) based on a single curve (Procedures 1, 2, and 4) are evaluated. Environmental factors such as measurement season and irradiation level on the correction performance are studied. The results show that Procedure 2 is relatively betterwith the relative root-mean-square error of the curve current as 2.6% compared to Procedure 1 (2.8%) and Procedure 4 (4.8%). Experimental tests using real I-V curves also show that Procedure 2 exhibits better robustness of correction. The new Procedure 4, whose correction coefficients are determined dynamically, performs poorly under partial shading and short-circuit bypass conditions. However, it achieves similar or better performance than Procedures 1 and 2 under degraded conditions, where the PV fault is generally not easy to detect, making the I-V correction more necessary. It is, therefore, a promising alternative correction procedure when it is difficult to determine the correction coefficients in advance. Finally, the pros and cons of the procedures are discussed with the suggestion of correction procedures under different conditions. The challenges and prospects are also provided.
