Heliostat

Principle of solar power generation by heliostat

A solar power tower, also known as 'central tower' power plant or ' heliostat ' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target). Concentrating. . Concentrating solar power (CSP) is naturally incorporated with thermal energy storage, providing readily dispatchable electricity and the potential to contribute significantly to grid penetration of high-percentage renewable energy sources. The term “heliostat” is derived from Greek roots: helios meaning sun, and stat meaning stationary or standing still. [PDF Version]
