Abstract
Recently we have proposed a low cost solar concentrator based on a large number of small flat mirrors that approximates parabolic surface needed for solar light concentration. In this work we describe an improvement of the concentrator support frame assembly. The improvement is connected with the design of the gauge/guages for support frame adjustment. The gauge has the parabolic edge and rotates in the central tube. Special nuts are moved up to the contact with parabolic edge of the gauge
Highlights
It is possible to subdivide solar concentrators in various types
Parabolic dish concentrators have many advantages: they produce high concentration ratio, permit scaling of installations up to residential power plants, parabolic dishes have been well tested during recent decades
New type of support frame for flat faced solar concentrator is developed using a structure assembled from bars and nodes
Summary
It is possible to subdivide solar concentrators in various types. Most popular are trough concentrators, tower concentrators, and parabolic dish concentrators. Large areas of solar concentrators are needed for solar power plants For this reason it is important to make the concentrators as cheap as possible. On the base of the analysis of this prototype we develop and propose a new approach to adjust the support frame of the solar concentrator. 150 Int J Adv Robotic Sy, 2011, Vol 8, No 4, 150-157 www.intechweb.org www.intechopen.com surface we propose a gauge or several gauges for adjustment of the nut positions on the support frame. In this paper we describe the method for facilitating the process of support frame adjustment for approximating the parabolic surface
