Design and Control of Generated Electricity Using Solar Powered Stirling Engine

Energy crises have been a big challenge for the world to overcome and researchers have come up with systems that use renewable energy sources to produce or utilize power. Solar-powered Stirling's engine is one of the most advanced sources of renewable energy for generating electric power via solar heat. Previously, Stirling's engine has been operated with biogas, coal, and molten salt, but these methods are not environment-friendly. The aim of this research is to create a system capable of transforming heat energy into an electric power source. Shaft and electric power at various temperatures and pressures have been tested. 3kW kinematic Stirling engine is successfully configured, tested, and analyzed. The receiver aper that absorbs the solar rays has been improved to an extent that its efficiency has increased to 80%. The results indicate that the efficiency of the proposed design is much higher as compared to previous designs.
