4.5. Component specifications
In the following section, the components' specification and their
costs are described. It is worth to mention that finding the true
costs of these components is hard and it can be significantly
different from one market to another and also can change
frequently. However a report published by IRENA (International
Renewable Energy Agency), “renewable power generation costs in
2014”, is used as a reference in order to reduce uncertainty about
the costs of renewable power generation technology [46]. In this
paper, in addition to the market survey and available literature, this
report has been used as a check point for a more accurate cost
estimation.
