Prospect of solar irrigation system over conventiona l irrigation system

Abstract

Bangladesh is a third world country with less economic growth. About 36% (Rahimafrooz) of GDP and 64% (Rahimafrooz)of its employment comes from agriculture. But our agricultural history is declining due to lack of irrigation facility .At the same time the existing irrigation facilities cost the government a huge amount of subsidy every year. So it’s a high time that we find an alternative way of irrigation so that our subsidy is reduced as well as people get water throughout the year. And gives birth to our project. In our project, we will be analyzing the feasibility of solar irrigation system for surface irrigation in the context of Bangladesh. Our main goal is to identify if the existing diesel run STW can be replaced by solar irrigation pump or not. RETScreen software has been used for the analysis.
