|This solar concentrator has a fixed-focus faceted
dish with a concentration of about 250 suns. This
system can be used for large fields connected to
the utility grid, hydrogen generation, or water

Concentrating solar power (CSP) technologies use mirrors to reflect and concentrate sunlight onto a single point where it is collected and converted into heat. This thermal energy can then be used to produce electricity.
Concentrating solar power systems are generally used for utility-scale projects. The mirrors in CSP plants focus sunlight onto a receiver that heats a high-temperature fluid, which is used to spin a turbine or power an engine that drives a generator. The final product is electricity.
Smaller CSP systems can be located directly where power is needed. For example, single dish/engine systems can produce 3 to 25 kilowatts of power and are well suited for distributed applications.
There are several varieties of CSP systems. Learn more about:
