Abstract :-Solar energy has been the most versatile and abundant energy source with a limitless supply of solar radiation. An evacuated solar collector nets solar energy from the sun is one of the most suitable and efficient collector types. This paper tried to answer why evacuated collector is preferred, their structure, types of evacuated collectors, applications, and issues reviewed. Many solar absorber systems in the market absorb solar thermal energy and convert it into work. But it has a limitation of working temperature. Many scientists are working to improve the working temperature of these systems. Evacuated solar collector gives promising results in this area, but it also limits lower working temperatures. In this paper, we discuss the application of solar evacuated tube collectors their working and principles. Many parameters affect the performance of the ETSC system, working fluid, coating, mass flow rate, and condenser structure. In this paper, we discuss the individual effect of that parameter and the combined effect of that parameter on the performance of ETSC. We found a significant result in a combination of the parameter. Nanotechnology has its role in improving the working temperature; we survey nanotechnology impact on performance enhancement. Based on all available literature, it can be said that an evacuated tube collector can propose a higher amount of efficiency than the other various types of collector. Few challenges have been identified which need to be wisely taken care of before installing it.
