National Solar Thermal Power Plant

A solar thermal power plant, essentially contains a solar field and a thermal power generation unit– similar to the one used in thermal power plants using coal or other fossil fuels. The solar field raises the temperature of a thermal fluid, which in turn provides necessary heat for producing saturated steam in the steam generator.

Solar energy | Definition, Uses, Advantages, & Facts | Britannica

The potential for solar energy to be harnessed as solar power is enormous, since about 200,000 times the world''s total daily electric-generating capacity is received by Earth every day in the form of solar energy. Unfortunately, though solar energy itself is free, the high cost of its collection, conversion, and storage still limits its exploitation in many places.
