Conclusion 
 
This academic piece of paper presents a comparative 
study of a two hybrid renewable energy systems, one 
connected to the local grid (on-grid) and the other is 
standalone (off-grid), without taking the influence of 
sensitive variables into consideration. This study occurred 
in Duhok , north of Iraq due to ease of solar and wind data 
access. The simulation results of the proposed system 
proved that hybrid solar-wind energy system connected to 
the local grid is most cost-effective than off-grid design for 
the similar load. Our hybrid system is better cost efficient 
than Duhok residential power grid, as our system cost unit 
is (0.0618 $\kWh) while Duhok residential electricity is 
0.1$\kWh.
