Abstract

This article provides a review on design and testing solar dish-Stirling system. In this type of systems, Stirling engine is depending on sun radiation as source of heat to providing the input energy. This project presents design calculations of different components of solar dish-Stirling system like received terminal energy from sun, solar collector dimensions, Stirling engine parameters, generator selection and calculations for solar tracking system. This paper addresses issues we are seeing during design and development of solar Stirling engine with generator to be sufficient acceptable for experimental and small wattage applications. This makes the energy usable in homes as a supplemental source of power or as an independent power source. The 3D model of system is prepared in solid work program to enable us starting the manufacturing and calculations. 3D model is showing the different components of solar Stirling system like the parabolic collector, receiver, Stirling engine, generator, and double axes Mechanism for solar tracking system. The design is implemented to include location and depends on properties that affect the performance based on the sun elevation angle, ambient temperature, the wind speed, and density of air (altitude). The solar collector is fabricated by using communication satellite fitted with polished sheets of Aluminum as a reflection material. Overall efficiency of designed solar Stirling system is between (17 – 20) percentages.
