Question 9What is the difference between photovoltaic solar systems and concentrated solar thermal systems?

A、Photovoltaic solar systems produce electricity using solar panels while solar thermal systems use mirrors to transfer heat from the sun into a working fluid.
B、Concentrated solar thermal systems require a large central tower that sunlight is directed onto, and photovoltaic solar does not.
C、Photovoltaic solar systems never produce as much energy as it takes to make them, whereas concentrated solar thermal systems do.
