The working performance of different solar panel models is represented through simulation results. The difference in the output occurs due to the differed voltage and current ratings of the panel. The derived voltage voltage and current ratings depend on the physical conditions prevailing in its vicinity and on its physical characteristics.

SIMULATED GRAPHS: The load demand to fulfill is 10 KW throughout the time scale except at 4 to 5 sec when it increases to 14 KW. Solar energy drops its irradiance to 15 % from 2 sec. Wind turbine initially rotating at 5m/s excels to base speed 12m/s after 0.5 sec. Its rotating speed is decreased to 25 % of its base speed. All these conditions are clearly observed in the below graph.The Maximum Voltage is of PV Array is observed at around 640 V. the curve below explains that the varying irradiance is the deciding factor of the maximum voltage derived.TABLE 7.7 Major Landmarks of Proposed Hybrid System
