Abstract
With the global energy demand surging and fossil fuel reserves depleting, solar energy has emerged as a pivotal alternative for clean and sustainable energy generation. Among solar thermal technologies, Flat Plate Collectors (FPCs) and Evacuated Tube Collectors (ETCs) are widely employed for domestic and industrial heating applications. This paper investigates the current energy scenario with a focus on solar energy as a replacement for conventional sources, and presents a comparative evaluation of FPCs and ETCs. The study highlights the distinct advantages of ETCs—such as higher thermal efficiency, better insulation, and improved performance under diffused radiation and colder climates. Through theoretical analysis and technical comparison, the findings reveal that ETCs consistently outperform FPCs, particularly in applications requiring high operating temperatures and year-round efficiency. As the need for reliable, low-emission energy systems grows, ETC-based solar heating systems offer a compelling solution for energy security and environmental protection.
