Concentrating Solar Technology

Non Imaging Concentrator ‘Accura’

Compound Parabolic Concentrators (CPC) Accura

A composite structure formed by use of parts of two parabolas arranged in such a way that both the parts share a common focus . This design insures all sun rays falling perpendicular to the aperture of CPC after one or multiple reflections from the reflecting surface of CPC finally converge at the focal area where an absorber tube holding heating media is place. The concentrated sun rays at the absorber are thus heatrays with double or more the amount of heat energy per meter square of the absorber. This results in faster heating with lesser heat loss as compared to standard collectors like flat plate or ETC tube collectors. Unlike Parabolic trough or dish these concentrators do not need daily tracking. This reduces any chance of regular maintenance.

Applications and usage of Compound parabolic concentrator (CPC)

Flat plate or ETC based standard solar collectors can deliver a temperature around 65OC at optimum efficiency. But most of the Industrial application fall in the temperature range of 60 OC  to 90 OC . Though one can achieve higher temperatures like 80OC by using Flat plate or ETC based standard solar collectors  but in the course of repeated circulations the amount of heat loss brings down the resultant efficiency of collectors making it un viable economically.

Whereas compound parabolic collectors ( CPC) deliver the temperature of 80 OC -85 OC at a optimum efficiency and even 90 OC at a little lower still economically viable efficiency.
