4. INTRODUCTION With the growing concern over environmental sustainability and the depletion of non-renewable energy resources, the need for efficient and renewable energy solutions has become paramount. Solar energy, being one of the most abundant and eco-friendly energy sources available, holds immense potential for addressing the energy demands of modern society This project focuses on the development of a Linear Fresnel Reflector (LFR) Solar Water Heater , a system designed to concentrate solar radiation to heat water. The LFR technology employs a series of flat, thin mirrors arranged in parallel to reflect and concentrate sunlight onto a central absorber tube, where water is heated.

6. MOTIVATION The increasing demand for sustainable energy solutions has underscored the importance of harnessing renewable energy sources to mitigate the adverse effects of fossil fuels on the environment. This project, focused on developing a Linear Fresnel Reflector (LFR) Solar Water Heater , is driven by the desire to contribute to sustainable energy solutions. The LFR system is particularly attractive due to its cost-effectiveness and ability to concentrate solar energy for various thermal applications, making it an ideal technology for regions with high solar insolation. By implementing the LFR technology in solar water heaters, this project aims to reduce energy consumption, lower costs, and promote the use of green energy in everyday applications.

7. Objective The main objective is experimental and numerical analysis to demonstrate the effectiveness of LFR solar system for heating water To develop a scalable LFR system that optimizes the use of solar energy for thermal applications, ensuring high efficiency and maximum energy absorption. To Fabricate a solar water heating system that is affordable, with a focus on reducing manufacturing and operational costs, making it accessible to a wider audience. To analyse the environmental impact by reducing reliance on fossil fuels and promoting the use of renewable solar energy. To assess the performance of the LFR Solar Water Heater under varying weather conditions.

8. Experimental Setup This Experimental setup consists of five essential structural elements: reflective mirrors, the receiver system, the trapezoidal cavity, the exterior support, and the interior support. The receiver system consists of four absorber tubes painted black to make the system highly absorbable direct solar radiation.
