Impact of Different Roof Types on Produced Power of Photovoltaic Rooftop System

The installation characteristics of PV systems are different in each area, some area uses a free standing PV panels on the ground, some area uses PV system on the roof that including the type of roof and the distance between the roof and the PV panels in the installation. A temperature of PV panels on the roof can rise substantially in comparison with that of free standing PV panels on the ground. That means, produced power of PV system on the roof may be reduced substantially. An aim of this experiment was to study comparison the produced power of PV panels with an install capacities 600 watts on the roof, between the metal sheet roof and fiber cement roof. The experimental results of the measurement of PV panels on the different roof types have verified and comparison power by simulation in PSCAD. The PV system on the fiber cement roof can produce power better than The PV system on the metal sheet roof because the fiber cement roof can reflect heat wave better than the metal sheet roof.
