: The development of solar photovoltaic (PV) technology has made it one of the most important sources of renewable energy in the world, necessitating the use of sophisticated modeling and parameter estimate approaches. With the Single Diode Model and Newton's Raphson method, this work presents a novel method for the precise determination of electrical properties of solar PV modules. The Single Diode Model is well known for accurately describing the electrical behavior of solar PV modules in a straightforward manner. However, getting accurate parameter values is crucial for producing energy efficiently since it makes it possible to monitor the system, find faults, and do preventative maintenance. In this study, we suggest a reliable and effective approach for predicting crucial parameters, such as the ideality factor (n), reverse saturation current (Io), series resistance (Rs), and shunt resistance (Rsh), which have a substantial impact on the performance of solar PV modules. Due to its quick convergence and capacity to generate extremely precise parameter estimates, Newton's Raphson method is chosen as the iterative numerical methodology. Our created computational program uses current-voltage (I-V) curves, temperature, and irradiation parameters from the specific solar PV module under investigation as input data. Extensive simulations and actual experiments on a variety of solar PV modules are used to confirm the effectiveness of the suggested approach. The results show that it is robust in parameter estimation even in the face of data noise, changes in the environment, and ageing of the module. Precise parameter estimate is essential for improving the overall effectiveness, dependability, and longevity of solar PV installations as well as for monitoring system performance in real-time and identifying and resolving any problems. In conclusion, this research makes a substantial contribution to the development of parameter estimate methods for solar PV modelling, providing a useful tool for the renewable energy sector. The proposed methodology, which combines the Single Diode Model and Newton's Raphson method, offers a workable strategy for increasing energy production, making sure solar PV systems are dependable and sustainable, and maximising return on investment. This study has the potential to advance solar energy technology and strengthen its position as a major player in the switch to sustainable and clean energy sources.
