Typical solar-powered bucket irrigation system when compared to the conventional energy sources. It does not exhaust natural resources and their main advantage is, in most cases, total absence of almost any air emissions or waste products. In other words, Solar Energy can be considered as an almost absolute clean and safe energy source. Benefits of Solar-powered irrigation systems Solar-Powered Irrigation Systems provide significant environmental benefits in comparison to the conventional energy sources, thus contributing, to the sustainable development of crop production activities for food security. It provides the following benefits:  Low maintenance, long lasting sources of energy;  Provides cost-effective power supplies for people remote from        the main electricity grid; Non-polluting and silent source of electricity; Convenient and flexible source of small amounts of power; Renewable and sustainable power, as a means to reduce global warming; Reduction of the emissions of the greenhouse gases and prevention of toxic gas emissions; Reclamation of degraded land; Reduction of the required transmission lines of electricity grids and Improvement of the quality of water resources. Conclusion Solar irrigation is becoming a viable technology to address a range of issues to name but a few:  The access to groundwater re- sources for irrigation, especially in arid and semi-arid areas;  The pressurization of water for localised irrigation;  Provision of energy to remote rural communities;  Solar irrigation is considered as a new way for replacing the conventional energy sources and plays an important role to reduce the load on electricity.  Solar irrigation project is financially feasible but limited due to its high initial cost and less operating time.
