Parabolic trough solar collectors (PTSC) are the best-utilized systems for solar thermal energy generation. PTSC is a line focusing collector responsible for concentrating and converting solar power into the form of heat energy that could be exploited.
Among the concentrating solar collectors, the parabolic trough is the most developed, cheapest, and widely used for large-scale applications in harnessing solar energy. However, it is not yet cheaper than conventional fossil fuels, and improvements and developments in the PTC are a must . 2.2. Parabolic dish Sterling engine
Modelling and economic analysis of a parabolic trough solar collector used in order to preheat the process fluid of furnaces in a refinery. J Therm Anal Calorimetry. 2019; 137: 2081.
In this study, various researches have been examined and it has been observed that advancements or improvements have been made to the various components of the Solar Trough. The use of Twisted tubes in the Receiver section is very common.
A comprehensive study has been conducted on PTC which covers the current research and development, a discussion of the design parameters, manufacturing of key components, applications, advantages, and disadvantages. Parabolic trough collectors (PTCs) are a promising technology for harnessing renewable energy to meet our needs sustainably.
