Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of …

The power block, thermal energy storage, and solar field are the three primary parts of CSP systems. The solar field concentrates the sun''s rays, which are subsequently converted into thermal energy. Therefore, the heat is used to generate steam, which in turn drives the power block to generate electricity.
