“…Bellows, whose thermal expansion is very low, helps in the expansion of the absorber tube without affecting the glass cover, and provide proper vacuum in annular space. While the getter absorbs hydrogen coming from the working fluid (oil) consequently stops the convection and conduction losses occurring due to the development of hydrogen in the annular region [18,19].…”

In recent decades, solar energy has emerged as the most promising renewable energy source and the best alternative to conventional energy due to its abundant availability, free, clean, no atmospheric hazards, eco-friendly, sustainable nature, and other factors. Because of its wide temperature range (up to 400 ℃), the parabolic trough solar collector is the most commonly used in concentrated solar power technology. A parabolic trough solar collector can be divided into two types based on its applications: low to medium temperature and medium to high temperature. The first category is widely utilized in household hot water, water purification, industrial process heating, desalination, and food processing, among other uses. Another is used in the electricity production process. The present review paper focuses on various aspects of parabolic trough solar collector, such as general description, geometrical interpretation, and mathematical models dealing with geometrical parameters and various types of performance calculations, trough modeling using a computational fluid dynamics tool, solar simulator, thermal resistance model, and losses. Furthermore, highlights on recent advances in thermal performance enhancement by various techniques, mainly by using modified working fluid (nanofluid), turbulators, and the modified surface of absorber tube, are presented in literature form and summarized in the table. This review paper will be of great help to researchers who have a keen interest in parabolic trough solar collector-based systems.

A solar water heater (SWH) converts solar radiation into thermal energy for various purposes, and its technology has experienced numerous developments. Many studies have focused on developing, optimizing, and analyzing the technological configurations of SWH to improve its thermal efficiency, but they rarely achieve 80% efficiency. This review aims to provide a broad overview of SWH, including the energetic and exergetic approaches and analyses, technological development, and examines advantages, disadvantages, and further developments. Various collectors of the SWH and related studies are also highlighted, and the results identify the technical and policy challenges of the implementation. Suggested potential solutions to these challenges are presented with further directions. Furthermore, this study also discusses the limitations of the current SWH technology by presenting the specifications and characteristics. It also presents the mathematical equation model often used, the technology potential, and the results of the latest studies and developments regarding SWH technology. The prospects for further development of the most promising SWH should be analyzed.
