Fig. 2 The case study location (Duhok) on the world map.
Both wind speed and solar
Irradiance data have been
obtained for Duhok, Iraq is determined by surface
meteorology and solar energy project (SSE)
of National
Aeronautics and Space Administration (NASA) [6], which
collects meteorology and insolation data for entire earth in
order to help in the evolution of renewable and clean energy
systems [7]. As showed
in HOMER program software, the
longitude and latitude of Duhok is 42°56'38.0" E,
36°51'36.4" N respectively. The mean daily irradiance per
each month showed in Fig. 3 for an annual average 4.85
(kWh/m
2
/day), whereas Fig. 4 reports the mean daily wind
speed per each month for annual average 5.67 (m/s). also
the mean daily irradiance per each month showed in Fig. 5 .
