Review of Parabolic Solar Concentrator by Using Different Types of Material Coating

Abstract

Abstract: The increasing global demand for clean and renewable energy sources has propelled research in solar energy harvesting technologies. Parabolic solar concentrators, renowned for their ability to focus sunlight onto a single point, have emerged as a viable solution for enhancing solar energy collection efficiency. This research review article presents a comprehensive overview of recent advancements in the performance and evaluation of parabolic solar concentrators through the utilization of different materials and insulation techniques. The article commences by elucidating the fundamental principles underlying parabolic solar concentrators and their significance in harnessing solar energy. A comprehensive review of the literature is then presented, highlighting studies that have explored the efficacy of diverse materials in the construction of concentrator surfaces. Traditional materials such as metals (e.g., aluminum, steel) have been widely used, but recent investigations have delved into innovative alternatives including advanced polymers, reflective coatings, and nanomaterials. The comparative analysis of these materials encompasses considerations such as optical properties, durability, cost-effectiveness, and manufacturing feasibility. Furthermore, the review critically assesses the impact of insulation integration on concentrator performance. Insulation strategies, ranging from passive thermal barriers to active cooling systems, are examined in terms of their ability to minimize heat losses and enhance energy capture efficiency. The synergy between material choice and insulation methodology is explored to delineate optimal configurations for various environmental and operational conditions.
