The document discusses compound parabolic concentrators (CPCs) for solar energy utilization. CPCs are concentrating solar collectors that can increase sunlight intensity without the need for tracking systems. CPCs are comprised of two parabolic mirror segments with different focal points that reflect and concentrate sunlight onto a small receiver area. They can operate at higher temperatures than non-concentrating collectors and do so in a cost-effective manner by collecting both direct and diffuse sunlight without tracking the sun's movement.

Solar collectors clasification 2 16MEOE1 SEU K.PRAKASH,ASP/MECH,SNSCT
Concentrating Collectors 3 16MEOE1 SEU K.PRAKASH,ASP/MECH,SNSCT • A solar collector that uses reflective surfaces to concentrate sunlight onto a small area • Concentrators can increase the power flux of sunlight hundreds of times • Concentrating PV modules/arrays track the sun and use concentrating devices to reflect direct sunlight • Collectors use both diffuse and beam solar radiation and do not require tracking of the sun
Need for Compound Parabolic Concentrator 4 16MEOE1 SEU K.PRAKASH,ASP/MECH,SNSCT  System operated at temperature below 100 ºC due to limited solar energy intensity on the solar panel  solar incident on a large area to a small enough area to increase solar energy intensity  parabolic trough concentrators, parabolic dish concentrators, lens concentrators, central tower concentrators, Fresnel concentrators  All the concentrators require accurate tracking systems  Compound parabolic concentrators (CPCs) collects solar energy without tracking systems.
Compound Parabolic Concentrator 5 16MEOE1 SEU K.PRAKASH,ASP/MECH,SNSCT  Compound Parabolic Concentrator comprised of two parabolic mirror segments with different focal points  The two parabolic surfaces are symmetrical with respect to reflection through the axis of the CPC  Relative high temperature operations with high cost effectiveness.
Compound Parabolic Concentrator 6 MEOE1 SEU K.PRAKASH,ASP/MECH,SNSCT  CPC consists of two pieces of reflectors, A and B  Aperture area on the top, through which the incident solar flux is accepted  Receiver area on the bottom  Reflectors A and B are two symmetric parabolas truncated and rotated around the CPC axis
