Performance of solar still units and enhancement techniques: A review investigation.

Drinking water requirements are rapidly increasing while the availability of drinking water is decreasing. Overcoming this problem requires a sustainable energy source, such as solar energy, to desalinate untreated water. The most essential and simplest application of brackish water desalination is solar distillation.

Technical and economic feasibility analysis of a PV grid-connected system installed on a university campus in Iraq.

In this article, a technical-economic study has been displayed to evaluate the productivity of grid-connected photovoltaic (PV) solar system in a campus of University of Zakho, Iraq. The feasibility of this study is based on performance ratio, capacity factor, cost of energy and yield factor. The analysis of the system has been performed using System Advisor Model (SAM) software and real data of Zakho city that is available in national renewable energy laboratory (NREL).
