Solar thermal energy is an innovative technology for harnessing solar energy for thermal energy. Solar energy can be tapped to produce electricity in two distinct ways. One is using a photovoltaic system that uses sunlight as it is and the other is by using solar concentrators. The basic idea is to translate the sun’s energy in the form of impending photons to usable electricity. Solar Concentrators, such as that used in CSP, can be used to concentrate sunlight to be used either in a Photovoltaic system or a solar thermal system. Though these two technologies essentially use focused solar light to produce electricity, they differ in the way sunlight is converted to electricity. In the case of a photo-voltaic device, the focused light is converted to electricity by exploiting the electronic properties of semiconducting materials, whereas in the case of solar thermal, the focused light heats up a transport fluid which is then used to generate steam which drives a turbine using the Rankine cycle generator. This talk will feature several technical aspects of Concentrated Solar Power generation.
