Two categories include Concentrated Solar Thermal (CST) for fulfilling heat requirements in industries, and concentrated solar power (CSP) when the heat collected is used for electric power generation. CST and CSP are not replaceable in terms of application. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-. . Solar thermal-electric power systems collect and concentrate sunlight to produce the high temperatures needed to generate electricity. All solar thermal power systems have solar energy collectors with two main components: reflectors (mirrors) that capture and focus sunlight onto a receiver. This fluid then transfers its heat to water, which then becomes superheated steam. Unlike photovoltaic (PV) systems, which. .
