Sustainability, Journal Year: 2025, Volume and Issue: 17(2), P. 461 - 461

Published: Jan. 9, 2025

This study investigated the performance optimization of nickel-cobalt (Ni-Co)-coated absorber panels in solar flat plate collectors (SFPCs) using response surface methodology for sustainable operation and optimized performance. Ni-Co coatings, applied through an electroplating process, represent a novel approach by offering superior thermal conductivity, durability, environmental benefits compared to conventional black chrome addressing critical concerns related ecological impact long-term reliability. Experiments were conducted evaluate efficiency Ni-Co-coated with without reflectors under varying flow rates, collector angles, reflector angles. The was calculated based on inlet outlet water temperatures, radiation intensity, panel area. results showed that SFPC achieved average efficiencies 50.9% 59.0% reflectors, demonstrating effectiveness coatings enhancing energy absorption heat transfer. A validated quadratic regression model (R2 = 0.9941) predicted process variables, revealing significant individual interaction effects. Optimization Box–Behnken design identified optimal parameter settings maximum efficiency: rate 1.32 L/min, angle 46.91°, 42.34°, yielding 79.2%. These findings highlight potential provide valuable insights into systems. Furthermore, introduction offers alternative chrome, reducing risks while efficiency, thereby contributing advancement renewable technologies.
