Abstract

There is a critical need to use the abundantly available solar energy worldwide due to the global energy crisis. The goal of this study is to demonstrate the residential use of a stirling engine powered by solar energy in Karachi, Pakistan. The design was carried out to produce a power output of 5 kW in order to address the issues with household and rural area power generating. The design was simulated using MATLAB. The use of solar energy as the engine's heat input was one of the design's key components. This allowed the engine to be built for locations with a lot of solar radiation. In regions with abundant solar energy, solar cookers, sun air warmers, and other appliances may be used. For power generation, however, the Stirling engine was chosen. Calculations of the sun intensity showed that 5 kW of Stirling engine output could be generated from 12 kW of solar electricity. The concentrator for concentrating and reflecting the incoming radiations to the Stirling engine was selected as a solar parabolic dish. This process heated the engine's working fluid, which then expanded and contracted due to thermodynamic forces to produce the engine's power strokes.
