Mitigation of energy consumption from conventional sources is now a prime challenge for the world

as the reservation of this energy is declining day by day. To compensate for these energies

people are now moving toward the utilization of renewable energy sources. Solar energy is one of them that has been used for a long time in various sectors. From this perspective

in this work

a solar-powered Stirling engine has been designed and developed

and its performance has been evaluated in terms of power generation. Several metrics

including temperature

thermal and electric efficiency

voltage

and speed of the engine

have been evaluated at various times to assess the functioning of the Stirling engine. After the analysis of the engine’s performance

it has been observed that a remarkable temperature range of 308–516 K and a pressure rise to 3.697 bar are found. Consequently

the engine achieves an impressive thermal efficiency of 40.3% and an electric efficiency of 15.03%. Additionally

the engine reaches a speed of 2680 rpm in just 180 seconds

demonstrating an output power of 4.68 W at the same speed. On the other hand

the generation of voltage has increased progressively and attained its maximum value of 2.6 V at 180 seconds. Besides

the highest irradiance has recorded 22 768 lux for optimal energy absorption. Finally

it may be concluded from the development

performance analysis

and prospective applications that the constructed Stirling engine can be sustainable and efficient in the renewable energy field.
