Experimental Analysis and Modelling of Solar Panel of Two-Diode Model (TDM) Parameters Dependence on Various Environmental Temperature and Solar Irradiance Changes in Naya Raipur Chhattisgarh.

Abstract

The growing use of renewable energy sources emphasizes how crucial it is to precisely simulate photovoltaic (PV) systems in order to maximize their efficiency in a variety of environmental settings. Although the two-diode model (TDM) is well known for accurately capturing the behavior of PV modules, environmental unpredictability makes it difficult to extract its parameters. Current approaches frequently aren't flexible enough to handle real-world circumstances like changing temperatures and solar radiation. By creating a hybrid methodology that extracts TDM parameters using both analytical equations and numerical optimization techniques, this study fills this gap. The study was carried out in summertime in Naya Raipur, Chhattisgarh, and found that temperatures fluctuated between 20°C and 31°C and that irradiance levels ranged from 25 W/m² to 245 W/m². The ideality factors (????1,????2) were found to range from 2.001 to 2.022 and 0.980 to 1.002, respectively, while important parameters such series resistance (????????) were fine-tuned to values between 0.333 and 0.368 Ω.
