Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The depletion of traditional energy leads to increasing demand on renewable energy. Among various forms of renewable energy, the solar panel are gaining importance and growing rapidly. Potovoltaic system performance affected by partial shading which due to near buildings, poles, passing clouds, fallen leaves, etc. Partial shading cause reduction in the power output and consequently, reduces the efficiency. This paper investigates the effect of various cases of partial shading (vertical string, horizontal string and single cell) at environmental condition on the current voltage and power voltage characteristics of photovoltaic panel which have in 88W power. The experiments were done for various parameters such as shading positions and ratio. The results showed that at 100% shading condition, the maximum power dropped by99.36, 43.7 and 41.15% for horizontal, cellular and vertical shading at the same solar radiation level in compared with their initial state value.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - El agotamiento de las energías tradicionales hace que aumente la demanda de energías renovables. Entre las diversas formas de energía renovable, los paneles solares están ganando importancia y creciendo rápidamente. El rendimiento del sistema fotovoltaico se ve afectado por el sombreado parcial debido a la proximidad de edificios, postes, nubes que pasan, hojas caídas, etc. El sombreado parcial provoca una reducción de la potencia de salida y, en consecuencia, reduce la eficiencia. Este trabajo investiga el efecto de varios casos de sombreado parcial (cadena vertical, cadena horizontal y célula única) en condiciones ambientales sobre las características de tensión de corriente y tensión de potencia del panel fotovoltaico que tiene una potencia de 88W. Los experimentos se realizaron para varios parámetros, como las posiciones de sombreado y la proporción. Los resultados mostraron que, en condiciones de sombreado del 100%, la potencia máxima disminuyó en un 99,36, 43,7 y 41,15% para el sombreado horizontal, celular y vertical con el mismo nivel de radiación solar en comparación con su valor de estado inicial.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - L'épuisement des énergies traditionnelles entraîne une demande croissante d'énergies renouvelables. Parmi les différentes formes d'énergie renouvelable, les panneaux solaires gagnent en importance et connaissent une croissance rapide. Les performances des systèmes photovoltaïques sont affectées par l'ombrage partiel dû à la proximité de bâtiments, de poteaux, de nuages, de feuilles mortes, etc. L'ombrage partiel entraîne une réduction de la puissance de sortie et par conséquent, réduit l'efficacité. Cet article étudie l'effet de différents cas d'ombrage partiel (chaîne verticale, chaîne horizontale et cellule unique) dans des conditions environnementales sur les caractéristiques de tension de courant et de tension de puissance du panneau photovoltaïque qui a une puissance de 88W. Les expériences ont été réalisées pour différents paramètres tels que les positions et le rapport d'ombrage. Les résultats ont montré qu'à une condition d'ombrage de 100%, la puissance maximale a chuté de 99,36, 43,7 et 41,15% pour l'ombrage horizontal, cellulaire et vertical au même niveau de rayonnement solaire par rapport à leur valeur initiale.…
