1. Introduction
Kuwait is located on latitude of 29.220
N and enjoys high solar radiation in most parts of the year (7.65
KWh/m2
.day). However, Kuwait suffers from dust and sand storms due to its very little vegetation,
dryness, weightless-textured surface soil and frequent unstable strong air currents [1]. The deposition of
aerial dust on PV modules reduces their transmittance and cause a reduction in their power output and
conversion efficiency [2-3]. This work experimentally investigates the performance of solar PV panel
under Kuwait environment and numerically simulates the effect of cooling in reducing the impact of dust
on the PV power output. Measurement of voltage, current, temperature and in plain solar radiation for
clean and dusty solar panels was carried out with time on a daily basis over a period of one year. The solar
panel used is made of HIT solar cells and has overall dimensions of 1580mmx798mm. Throughout this
