Abstract

The objective of this study was to demonstrate the potential of convex lenses as an alternate approach in solar water heating. The Convex Lens Solar Water Heating System (CSP) consists of convex lenses, and a copper thermally insulated receiver tube. The convex lenses are mounted on the top of the collector, where sunlight is collected and directed on the rising tube, maximizing the effectiveness of solar radiation capture and rapidly heating the water inside the tube. In this study, a series of experiments were carried out at different flow rates of 4,6 and 10g/s. The results showed that the useful heat obtained increases from 46.3 to 238.6 watts, while the highest output temperature is 41.5 °C with a flow rate of 4 g/S, and it decreases with the increase in mass flow rate and the decrease in solar intensity.
