%X Photovoltaic power generation systems have infinite energy 
resources and are environment friendly technology. But low 
efficiency and high cost per unit output power is the biggest 
problem of these systems. Accommodation of PV panels in the 
roof top creates a practical constraint of ˇ°partially shaded 
conditionˇ± or ˇ°Non uniformly illuminated array conditionˇ±. The 
power-voltage characteristic of photovoltaic arrays operating 
under partial shading conditions exhibits multiple local maximum 
power points due to the usage of bypass diodes
