How does solar thermal energy work? Types of systems
Thermal energy by heating fluid. Mechanical energy using a Stirling engine. There are three types of solar thermal technologies: High- temperature plants are used to produce electricity working with temperatures above 500 ºC (773 kelvin). Medium-temperature plants work with temperatures between 100 and 300 degrees Celsius.
