Study of Dust Effect on Photovoltaic Module for Photovoltaic Power Plant

The effect of dust on photovoltaic module to decrease the electrical energy output from PV module by obstructing the solar radiation which is absorbed by PV module. This research studied the effect of dust on PV module and also developing a mathematical relationship between dusts on PV module and decreasing from electrical energy output of PV power plant. The PV module which is studied in this research consist of three types, 40 W of amorphous silicon, 75 W of mono crystalline silicon and 125 W of multi crystalline silicon. The test of this work can be divided into two groups; first is the PV module which is cleaned and second is PV module without clean. The data of the test is recorded for 5 months after that analyze and develop a mathematical relationship model between dust on PV module and decreasing of electrical energy output from PV power plant.
