ABSTRACT:
This research paper presents the design, development, and performance analysis of a compact solar water heating system specifically engineered for residential rooftop applications. The study addresses the growing need for sustainable and cost-effective domestic water heating solutions in the context of rising energy costs and environmental concerns. The proposed mini solar water heater utilizes thermosiphon circulation principles and incorporates optimized collector geometry to maximize thermal efficiency within space constraints typical of urban residential settings. Through computational fluid dynamics (CFD) analysis and experimental validation, the system demonstrates a peak thermal efficiency of 68% under standard test conditions, with a daily hot water production capacity of 80-120 liters at temperatures ranging from 45-60°C. The system features a modular design with corrosion-resistant materials, enabling easy installation and maintenance while maintaining a competitive cost structure. Economic analysis reveals a payback period of 3.2 years with projected operational savings of $450 annually for average household consumption patterns.
