Abstract
The accumulation of dust particles on the surface of photovoltaic
(PV) panel greatly affects its performance especially in the dusty
areas. In the present work, an experimental and theoretical study
has been carried out to investigate the effect of sand dust concentration
on the efficiency of PV panels. A stand-alone PV system is designed
to carry out this work. The I ? V characteristics have been measured
simultaneously for both clean and dusty modules. It has been found
that the short circuit current and the maximum output power decrease
significantly as dust particles start to accumulate on the panel
surface up to a concentration of 1 g/m 2 , but the rate of decrease
is slower for concentrations beyond that value. The reduction in
short circuit current in one sample of study is found to be ∼⃒40%,
whereas it is ∼⃒34% in the maximum output power. In contrast,
it is stated that the open circuit voltage is not sensitive to sand
dust accumulation. A significant degradation in
