Design Of A Single-Cover Solar Collector To Heat Water For A Typical Building

Abstract

The increasing global demand for hot water, coupled with the environmental impact of traditional energy sources, underscores the need for sustainable alternatives. Solar energy, as a clean and renewable resource, has emerged as a promising solution. Libya, with its high solar radiation and favorable climate, offers an ideal environment for harnessing solar energy for domestic water heating. This study evaluates the performance of a flat-plate solar collector designed to supply hot water for a typical household in Brega, Libya. The system was optimized for local climatic conditions to maximize efficiency. In Brega, solar radiation intensity reaches 980 W/m², and the collector has an area of 1.80 m² with a 45°C tilt angle. The absorber incorporates copper pipes, and the water storage tank, utilizing the thermosyphon principle, has a capacity of 40 liters. A 10-hour performance test conducted on June 15th 2024 yielded positive results, demonstrating the potential of solar water heating in the region.
