Influence of Reflective Surface Type on Solar Energy Concentration Efficiency for Concave Solar Dishes
Solar energy considered the most important renewable energies; one of the most important applications of solar energy is concentrating solar radiation by concave solar dishes to give thermal energy, which used in many purposes such as warming, heating water, and generating electricity. Therefore, it is important selecting reflective surface type to increase efficiency, and compromise between cost and efficiency. The current study aims to determine the most effective and efficient surface for three different surfaces to reflect solar radiation in thermal energy form, which absorbed by the water that flows in the spiral copper coil at focus area with three flow rates. The surface of nickel chrome gave higher temperatures and higher efficiency than aluminum foil and reflective glass surfaces. Where the average temperature of the receiver was 172 °C before water flow, 68 °C for outlet water from the spiral coil at flow rate 1.48 cm3/s when using the nickel chrome surface as a reflective surface.
