Abstract
The current article presents an analysis of the impact of shading on the characteristics of a solar string, with and without the presence of bypass diodes. A solar string consisting of four solar modules was used for this purpose. Experiments were sequentially conducted by connecting one, two, and four bypass diodes. The study was conducted in laboratory conditions using an artificial light source while maintaining the cell temperature mode. The obtained results were analyzed concerning the volt-ampere characteristics, power characteristics, and the coefficient of performance of the photovoltaic string. All the obtained characteristics are compared with the characteristics of the non-shaded solar string.
