Design and Performance Evaluation of an Enhanced Solar Thermal Collector

Abstract

This research aims to design and analyze a Scccs2 solar collector with a convex front surface and a corrugated absorber surface that reflects the incident solar radiation via mirrors. The design features a convex front surface that increases the angle of solar radiation capture, while a wavy and convex absorber surface increases the surface area exposed to the sun. In addition, reflective mirrors are used to direct solar radiation to copper tubes mounted above the absorber surface, increasing the efficiency of the Scccs2 solar collector. The new geometry significantly increases the efficiency of the Scccs2 solar collector in converting solar energy into thermal energy.The testing also demonstrates the effect of adding the absorber surface and tubes in a wavy -convex shape on the performance of the Scccs2 collector. To increase the collector's ability to retain thermal energy, two tanks (B1-B2) are installed inside the collector. Scccs2 records (Tout= (65-95) °C, B2= (45-85) °C) for the period from November 2024 to June 2025. The Scccs2 model is capable of operating in partly and completely cloudy weather. In partly cloudy weather, Scccs2 records (Tout= 70°C, B2= 50°C). In completely cloudy weather, it records (Tout= 49°C, B2= 32°C).
