Since the final objective of the system is very specific, the structure and solar tracking of the collector are also designed. Antecedentes paraguay tiene una economia fuerte y medianamente diversificada. Optical design of a solar parabolic concentrating collector based on trapezoidal reflective petals 715 is carried out to improve the overall performance of system. The parabola is commonly used as the curve for solar cookers because of its ability to reflect incoming light with an incoming angle of 90 degrees to a single focus point. Reforma 1, colonia palmira, cuernavaca, 62490, morelos. In this paper, two different reflective surfaces are used to increase the optical efficiency of a parabolic trough solar collector. Parabolic troughs, which are a type of linear concentrator, are the most mature csp technology with over 500 megawatts mw operating worldwide. In this case, a parabolic mirror concentrates incident solar irradiation onto a much smaller receiver area, greatly decreasing heat loss and maximizing the available energy from the sun. In this paper work the performance analysis of parabolic solar dish collector is done with the use of different reflecting materials.
