23 CONCLUSION This system can fulfil the energy demand for irrigation, fisheries and food processing of the farmers of remote areas. The conventional solar irrigation system will be more efficient and economically viable, by implementing this project. Maximize the annual solar energy utilization with higher carbon credits. Initial high investment will attenuate with decreasing of international market price of solar panels that will make the project more economically viable. Moreover, Government subsidy or any NGO s fund will make the project more affordable by local farmer. 23
