Comparison of Two Photovoltaic Micro-Irrigation systems for a Land at Mersin in Mediterranean Region.

Solar energy which is the most abundant source of the renewable energy sources is commonly used in all areas in the world. In this study, two micro-irrigation systems supplying energy requirement by using photovoltaic arrays are designed for a land with 10 decares at Mersin in Mediterranean region. One of micro irrigation system named as direct PV micro-irrigation system supplies water from an underground well having the depth of 100 m and the other system called indirect PV micro irrigation system supplies water from water tank. These micro-irrigation systems are compared with each other in terms of cost. It is deduced that the indirect PV micro-irrigation system is more useful than the direct PV micro-irrigation system. The indirect PV micro-irrigation system is cheaper than the direct PV system and the duration of investment payback of indirect system is shorter than the duration of investment payback of the direct PV micro-irrigation system.
