Solar Stirling Engine Vs. Solar Panel
The solar Stirling engine is a thermal solar power reciprocating piston engine. The engine has a higher efficiency than a gasoline or diesel engine. The Stirling engine is based on the external combustion engine invented by Scottish minister Robert Stirling in 1816. His company manufactured the Stirling cycle engine from 1818 to 1922.

Technology
Heat is then transferred to a Stirling engine through a heat transfer fluid. The Stirling engine runs a generator for electricity and heat between 55-65°C (130-150°F) to be supplied on demand, at hours when the sun is not shining or when direct production from solar PV is insufficient – enabling renewable power for all hours of the day.

Review on solar Stirling engine: Development and performance
The idea of using solar energy in the Stirling engine was applied by integrating solar concentrators to the Stirling engines. The dish-Stirling systems first convert the thermal energy into mechanical energy using concentrators and Stirling engine, and then mechanical to electrical conversion is done using generators [3], [4].

How Stirling Engines Work | HowStuffWorks
A Stirling engine uses the Stirling cycle, which is unlike the cycles used in internal-combustion engines. The Stirling cycle uses an external heat source, which could be anything from gasoline to solar energy to the heat produced by decaying plants. No combustion takes place inside the cylinders of the engine.
