Types of Concentrated Solar Collectors and their Advantages

Concentrating solar collectors in Concentrated Solar Power (CSP) systems concentrate sunlight on a receiver where it heats a heat transfer fluid. Subsequently, it exchanges the absorbed heat to water to produce steam for powering a steam turbine-generator (STG) to generate electricity.

Concentrated solar power

OverviewCurrent technologyComparison between CSP and other electricity sourcesHistoryCSP with thermal energy storageDeployment around the worldCostEfficiency

CSP is used to produce electricity (sometimes called solar thermoelectricity, usually generated through steam). Concentrated-solar technology systems use mirrors or lenses with tracking systems to focus a large area of sunlight onto a small area. The concentrated light is then used as heat or as a heat source for a conventional power plant (solar thermoelectricity). The solar concentrators use…
