Linear Fresnel refers to a type of line-focus concentrated solar power (CSP) technology that utilizes an array of low-profile, flat or nearly flat primary reflectors to track the sun while a fixed receiver assembly collects heat.
The linear Fresnel solar collector is a line-focus system similar to the parabolic trough. Unlike troughs, however, it uses an array of nearly flat reflectors to concentrate sunlight. Normally these are one-axis tracking, flat mirrors fixed to a steel structure on the ground.
A linear Fresnel Reflector (LFR) consists of an array of linear or curved mirror strips, behaving as a Fresnel lens, which concentrates solar radiation on to a fixed receiver mounted on the top, see Fig. 3. Secondary concentrator can be used with these systems to increase the concentration ratio.
Two main systems are the solar trough and the linear Fresnel (LFR) based collector. Although the trough based system has proven itself over many years of operation in different applications, the Fresnel system is emerging as an alternative with several advantages.
The main reason for this is the search for cheaper solar field solutions. The considerable economic advantages of Fresnel collectors are principally related to their constructive simplicity. In
