Bangladesh is a riverine country. Approximately 24,140 Kilometers of entire length in this country are surrounded by 700 rivers including tributaries. In Bangladesh around 1,280,000 fishermen exist, among them 770,000 inland and 510,000 marine fishermen whose income entirely depends on fisheries. Bangladeshi fishermen mainly use trawler for fishing purpose in sea and river. Roughly 2000 trawlers are registered in “Fishery Ghat” under Sadar Ghat Thana in Chittagong, Bangladesh. Those trawler boats require electric power at night for fishing and lighting. Currently, in trawler, electric power is supplied by battery which is charged through a dynamo synchronized with trawler engine. This dynamo requires diesel to serve electric power. In present scenario to fulfill electric power demand each trawler utilizes 30 liter diesel in a ten day trip at fishing time in sea or river. The present system’s efficiency is less than 15% and also pollutes environment. Besides British Petroleum’s “Statistical Review of World Energy” published in mid 2014 asserted, crude oil reserve will be finished within next 40.5 years. In such conditions, the conventional method can no longer be considered as the optimum solution for the energy generation system. Hence, the renewable energy sources have taken over the electricity generation process. Renewable energy sources are of many types such as solar, wind, biomass, biogass etc. Among all of these energy sources, solar energy is one of the very significant sources of renewable energy. This paper will discuss about the modeling and implementation of a fishing trawler using solar energy. This system is entirely green, free and economically feasible solution for trawler. The Life Cycle Cost Analysis (LCCA) of this proposed design is mathematically modeled via software. The LCCA result specifies Saving to Investment ratio (SIR) and Net Profit Value (NPV) of this renewable system is greater than 1.00 and also indicates BDT 478191.90 will be the net benefit for each trawler after 20 years payback time which saves approximately Tk 2000/month/trawler. This huge revenue may bring socioeconomic change in life of Bangladeshi fishermen.
