High-Efficiency Solar Thermal Systems: Design And Performance Analysis

Abstract

High-efficiency solar thermal systems have emerged as a viable way to harness solar energy to satisfy the world's growing energy needs. The types of systems that use solar heat, the materials used in FPCs, ETCs, and CSP systems, as well as their performance, are the main topics of this study. It is feasible to conclude that ETCs are more efficient than CSP technologies because they employ fluids that transfer heat at high temperatures, such as molten salts, vacuum insulation, and sophisticated absorber coatings. The efficiency of the system is increased by 10% when the tilt angle and orientation are increased, according to a simulation and experimental study.

Sensible and latent heat storage systems were found to have high thermal retention, which made it possible to provide heat during times of low solar radiation. The economic and environmental analysis showed that CSP systems, especially solar tower type, reached the lowest LCOE and the highest CO2 reduction potential to help combat climate change. The enhanced control system was used for monitoring the performance and pursuing optimal system operations, taking into consideration improved efficiency.

This paper gives an overview of high-efficiency solar thermal systems and brings out specific information regarding design improvement, storage systems and its uses, and environmental compatibility. It is anticipated that improvements in the materials and the system layouts will further improve the feasibility of solar thermal systems.
