How does solar thermal work?

Instead of converting sunlight directly into electricity, as photovoltaics does, solar thermal harnesses the sun's energy to heat a fluid called a heat carrier and then uses that heat to generate electricity or provide heat for industrial or domestic applications.

What is solar thermal?

Solar thermal encapsulates any technology that takes sunlight and converts it into heat. That heat can then be used for three primary purposes: to be converted into electricity, to heat water for use in your home or business, or to heat spaces within your house.

How is solar thermal energy obtained?

Solar thermal energy is obtained by converting solar heat into useful energy. This is achieved through various technologies. Parabolic solar collectors use curved reflective mirrors to concentrate sunlight onto a receiver containing a thermal fluid. The heat generated is used to produce steam and generate electricity.

Does solar power use heat and light?

Confusion over the impact of heat and light in solar power starts with the fact that there are different types of solar power. One type of power, called solar thermal, does use the sun’s light to generate heat which can be used for things such as household hot water or to generate steam to drive turbines and generate electricity.

How is solar thermal electricity generated in a CSP plant?

Solar thermal electricity in a CSP plant is generated in two stages. In the first stage, solar energy is captured in the collectors and is used to heat a working fluid which may be water or molten salt. The second stage deals with the energy transformation in which electricity is generated by allowing steam to run a turbine or an engine.

Does solar energy produce electricity?

Rapidly decreasing costs of PV as well as concentrated solar thermal electricity have resulted in a rapid expansion of solar electric power generation. As a result, to date, solar energy has been mainly associated with electricity production.
