Using the genetic algorithm to determine the parameters of photovoltaic cells and panels

Heuristic methods are used more and more often to determine the parameters of photovoltaic cells and panels. The results obtained using these methods are better than the results obtained through analytical ones. The genetic algorithm is used in this paper to determine the major parameters of the photovoltaic cells and panels for a one diode model. The current voltage characteristics of the photovoltaic cells are measured under illumination in lab conditions and for the photovoltaic panels in natural sunlight conditions.
