Feasibility Study of Theoretical Efficiency Calculation for Flat Plate Collectors in Solar Water Heating Systems

Abstract

Solar energy stands as a paramount clean, abundant, and renewable power source holding remarkable potential to address our escalating energy needs. Among its crucial utilization methods, solar water heating systems integrating flat plate collectors (FPCs) emerge as vital contributors in harnessing and converting solar energy into utilizable heat. This study delves into the realm of FPCs' theoretical efficiency assessment, employing mathematical models and factoring regional weather conditions to meticulously evaluate the efficiency of single-glaze and double-glaze collector variants. The outcomes spotlight the single glaze collector's efficiency at 0.669 and the double glaze collector at 0.713, underscoring the discernible performance gap. In a landscape where industries, hospitals, residences in Kandahar, and comparable settings extensively depend on hot water, often derived from fossil fuel-driven heating, this research's implications hold particular relevance. By transitioning towards solar water heating, this study not only underscores a concrete method to curtail carbon emissions but also to significantly reduce energy expenses linked with conventional heating techniques. The findings beckon a departure from the status quo, emphasizing that cleaner energy options are attainable, even for regions demanding hot water requirements. As society navigates complex decisions concerning energy sourcing, embracing solar water heating stands as an auspicious stride towards a sustainable future, beckoning us to collectively embark on a path of energy-conscious choices for the greater good of our planet and the generations that will inhabit it.
