The application of solar ethanol fuel making has energy savings also help in reducing the cost of Manufacturing. The solar ethanol fuel manufacturing also has environmental benefit and doesn’t involve fossil fuel for process which emits large amount of emission. This also helps to reduce our dependency on foreign country and help us in improving country economy too Current study is covering two promising Renewable energy sources viz. solar energy as a renewable source for Manufacturing of Ethanol as bio-fuel. Both are the thrust area for study worldwide.The performance panel depends on the environmental factors, which is solar radiation and operating temperature. These environmental factors will be reduced the effectiveness of Flat plate solar panel due to increase in operating temperature of Flat plate solar panel. To improve the performance of Flat plate solar panel by using different types of augmentation technique are used which include active passive and combine technique.. In passive technique use twisted tape or wire coil different type of insert's which is placed in flowing fluid in tube then turbulence will create. Then laminar flows gets convert in to turbulent flow which result increases in heat transfer rate is used to overcome the problem of low efficiency of Flat plate solar panelthis mechanism is one way for maintaining a low operating temperature during its operation period. The experimental results mentioned that the decrement of operating temperature and increase the power output of the Ethanol Production. . [ABSTRACT FROM AUTHOR]
