Abstract
This brief presents an iterative approach using the Lambert W equation to solve the current–voltage (I-V) dependence in a four-diode solar cell model. The model has been rigorously tested using two well-known solar panels from existing literature, demonstrating its efficiency in terms of the number of iterations required to achieve the desired level of accuracy. Additionally, a novel formula for calculating the Root Mean Square Error (RMSE) is proposed, improving prediction accuracy. The results underscore the significant innovation this research brings to the field of solar cell modeling and optimization.
