Solar energy harnessed through thermal collectors offers a vital pathway to address global warming. Several types of equipment exist to capture thermal energy for practical use, including flat plate collectors, evacuated tube collectors, and parabolic concentrators. Among these technologies, evacuated tube collectors are particularly prominent because they experience lower heat loss than alternative systems. An overview of operational contexts demonstrates that evacuated tube collectors support multiple practical uses, specifically solar water heating, solar drying, solar air heating, and solar desalination. When evaluated across these diverse thermal operations, evacuated tube collectors emerge as the most suitable apparatus for solar thermal applications, providing efficient heat capture across domestic and industrial processes that require reliable thermal energy transfer.
Mitigating the impacts of global warming requires effective methods to capture renewable solar power. By minimising heat loss, evacuated tube collectors provide an effective means to harness thermal energy. Understanding their suitability across varied processes, from drying produce to purifying water and heating spaces, helps guide the adoption of cleaner technologies to replace fossil fuel-driven heating and thermal systems.
The review highlights practical uses for evacuated tube collectors in solar water heating, solar drying, solar air heating, and solar desalination. Technology developers, equipment manufacturers, and commercial operators in agricultural drying or water treatment can deploy these collectors where heat conservation is critical. The referenced systems represent applied, established technologies across multiple thermal sectors, though the abstract does not provide specific implementation stages or commercial performance benchmarks.

Solar energy is a need of an hour. At present, due to the global warming effect, researchers are moving towards the research work on solar energy. Solar energy can be harnessed by solar thermal collectors. Flat plate collector, evacuated tubes collector, parabolic concentrator, etc. are used as efficient apparatus to use thermal energy for useful application. Among the above collectors, evacuated tubes collector is famous as compared with others due to the lower heat loss. This review paper shows various applications of evacuated tubes collector like solar water heating, solar drying, solar air heating, and solar desalination. It has been found that evacuated tubes collector is the most suitable apparatus for solar thermal applications.
