Abstract
This paper reviews recent advancements in Evacuated Tube Solar Collectors (ETSCs), highlighting their high efficiency in harnessing solar energy for heating applications. ETSCs outperform traditional flat plate collectors, especially in colder climates, due to their superior heat retention and ability to utilize diffuse solar radiation. Integrating nanofluids, Phase Change Materials (PCMs), and optimizing designs can further enhance their performance and efficiency. Despite their higher initial costs, ETSCs offer significant long-term benefits in both residential and industrial applications. Future research should focus on improving tube durability, exploring advanced materials, and evaluating economic impacts. This paper focuses specifically on evacuated solar collectors, providing relevant background information and highlighting potential opportunities for further improvement of these systems.
