Low scale solar irrigation systems have shown their potential in rural irrigation projects around the world, especially where there is no grid connection and no transportation facility. With continuing price decreasing of solar module and solar pump due to market competition, they are becoming economically attractive and growing experiences is gained in irrigation such as low scale multistage irrigation, medium head and high head irrigation system. There is still lack of information although it has wide scope. The main purpose of this study is to contribute to a better understanding of the potential of low scale solar pump to deliver water at different height distributing equal power from a small Photovoltaic panel according to interlock system of the pumps. It is, in fact, of paramount importance to identify the potential contribution of solar irrigation system for rural development in order to gain further financial commitment for low scale irrigation projects and program and to design appropriate solar irrigation projects for terrace field. It helps to provide the option for irrigation facility for terrace field in Nepal. One of the main lessons learnt through this study is that the pay back period is very short and there are no maintenances for the system also. It is hoped that this document contributes to the generation of ideas and discussions among the different institutions involved in providing low scale multistage solar irrigation services to rural area.
