Performance Investigation of Evacuated Tube Solar Heating System: A Review

Abstract

The solar energy is the most abundant and eco-friendly source of energy on earth. It is the most readily available source of renewable energy on the earth; the earth receives millions of watt of energy per day which is coming in the form of solar radiation. Solar energy is captured by several conventional and new type of solar collectors of which the evacuated solar collector is the most efficient and suitable collector among all kind of solar collectors. The present study is an effort to summarize the research work proposed by various researchers on the evacuated tube solar heating system (ETSHS), their applications, and suitability for various solar thermal engineering systems. The previous studies on ETSHS were mainly associated to their suitability and performance for domestic applications. Therefore, this review is focused on investigation of the performance of ETSHS for domestic and industrial uses and the factors that influence the collector efficiency.
