As solar energy is an important source of renewable energy resource. Sun radiation is being used as renewable energy, a combination of solar collector dish type and a Stirling engine is generally referred to the solar power. In this type, Stirling engine is depending on sunlight as source of heat to providing the input energy. This project presents different components and various configurations alongside with the feasibility of using solar energy as a source of heat for a Stirling engine. In addition to this, calculation of different components of Stirling engine and parabolic dish like sun heat calculations, Stirling torque calculations, generator calculations, and calculations for following and tracking the light intensity to get maximum solar power. This paper addresses issues which we saw 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. 3D model is showing that is consisting of the parabolic collector, receiver, Stirling engine, and generator. The 3D model is prepared in solid work to enable us starting the manufacturing and calculations. 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). Here experimental study is conducted on small-scale solar parabolic Stirling engine with generator. The solar collector is fabricated using satellite dish antenna fitted with polished sheets of aluminum. Low power is consumed to find the maximum power and highest light intensity. The applications of solar Stirling have green and clean energy generation from sun energy. Overall efficiency of solar Stirling power of system is expected to be around (36-24) percentage.
