CT: Solar energy is the most abundant, widely distributed and clean renewable energy resource. Since the insolation intensity is only in the range of 0.5 – 1.0 kW/m2, solar concentrators are required for attaining temperatures appropriate for medium and high temperature applications. The concentrated energy is transferred through an absorber to a thermal fluid such as air, water or other fluids for various uses. This paper describes design and development of a ‘Linear Fresnel Mirror Solar Concentrator’ (LFMSC) using long thin strips of mirrors to focus sunlight on to a fixed receiver located at a common focal line. Our LFMSC system comprises a reflector (concentrator), receiver (target) and an innovative solar tracking mechanism. Reflectors are mirro strips, mounted on tubes which are fixed to a base frame. The tubes can be rotated to align the strips to focus solar radiation on the receiver (target). The latter comprises a coated tube carrying water and covered by a glass plate. This is mounted at an elevation of few meters above the horizontal, parallel to the plane of the mirrors. The reflector is oriented along north-south axis. The most difficult task is tracking. This is achieved by single axis tracking using a four bar link mechanism. Thus tracking has been made simple and easy to operate. The LFMSC setup is used for generating steam for a variety of applications.

N: Linear Fresnel Solar Concentrator: The solar concentrator arrangement proposed for the factor e farm solar turbine implementation is of the linear fresnel type. Linear, as it’s focus is a line as opposed to a point, and fresenl as it is made of many small reflectors as opposed to a monolithic parabolic trough.
This is a discussion of the theory of linear fresnel solar concentrators, and a justification of the design decisions siezed upon by the factor e farm team.
