这项工作的重点是在印度中东部（21.16°N 81.65°E, Raipur, Chhattisgarh）的热带潮湿和干燥气候条件下单晶和多晶硅太阳能光伏（SPV）模块的性能比较。这项研究将有助于在该国中东部地区选择系统安装的SPV模块。为了进行比较分析，我们使用绩效比（PR）和效率作为绩效指标。采用阵列平面辐照度（POA）来确定组件的效率。分解和转置模型根据测量的全球水平辐照度计算POA值。对非雨季（2020年10月至2021年3月）6个月的数据进行了系统分析。特别关注太阳辐照度、环境温度和组件温度这些影响光伏组件性能的参数。十月份的辐照度和温度变化最大。最高平均温度（51-52°C）出现在10 - 11月，而最低平均温度（单si为34°C，多晶硅为36°C）出现在12月。月平均POA辐照度在2月最高（568 W/m2），在12月最低（483 W/m2）。结果表明，在各种天气条件下，单晶SPV组件的性能都优于多晶组件。12月单晶硅和多晶硅面板的pr最大值分别为0.89和0.86。10月和11月模块温度越高，热损失越大；12月温度越低，热损失越小。根据实测数据计算出了产能，并与PVSyst模拟结果进行了比较。
This work focuses on the performance comparison of monocrystalline and polycrystalline Si solar photovoltaic (SPV) modules under tropical wet and dry climatic conditions in east-central India (21.16° N 81.65° E, Raipur, Chhattisgarh). This study would help to select the SPV module for system installation in the east-central part of the country. For comparative analysis, we used performance ratio (PR) and efficiency as figures of merit. The plane-of-array (POA) irradiance was used to determine the efficiency of the modules. The decomposition and transposition models calculated the POA values from the measured global horizontal irradiance. The data were analysed systematically for 6 months in the non-rainy season, from October 2020 to March 2021. Special attention was given to solar irradiance, ambient temperature and module temperature—the parameters that affect the performance of PV modules. The month of October showed the highest variation in irradiance and temperature. The highest average module temperatures (51–52°C) were observed in October–November, while the lowest average module temperatures (34°C for mono-Si and 36°C for poly-Si) were observed in December. The highest value of average monthly POA irradiance (568 W/m2) was observed in February and the lowest (483 W/m2) in December. The results showed that the monocrystalline SPV module performed better than the polycrystalline module under all weather conditions. The maximum observed values of mono-Si and poly-Si panel PRs were 0.89 and 0.86, respectively, in December. Thermal losses were higher with higher module temperatures in October and November, and lower in December due to lower temperatures. The energy yield was calculated from the measured data and compared with PVSyst simulations.
