Compound Parabolic Concentrator

Compound Parabolic Concentrator

Compound Parabolic Concentrator

The compound parabolic reflector is constructed by using segments of two parabolas. These parabolas are arranged in such a way that the focus of both coincides at same line. Because of the Specific shape of the surface, all the incoming rays are reflected and concentrated on absorber/ receiver tube. The receiver tube is placed on the focal band. The fluid inside is heated up due to concentrating solar irradiation thus received by the surface of the tube. Receiving concentrated radiation on small area helps achieve higher temperature faster.

How to install?

CPC system installation could be done in two ways.
The choice of orientation of CPC collectors will depend on the latitude of the location.
The Orientation of the CPC and manifold will depend on the latitude of the site. For any site having latitude between 25o S to 25o N, the manifold should be oriented lengthwise north south and the CPC should be oriented lengthwise east west.
For sites having larger latitudes than these means more than S25 and N25, the manifold should be oriented lengthwise east west and the CPC should be oriented lengthwise north south. For these sites the system needs to have a tilt of 30 o to 45o facing the other hemisphere of earth. If the site is in the northern hemisphere the collector should be facing south and vice a versa. For achieving the tilt manifold stand is elevated by calculated height.

How much CPC would I require & what is the Total Foot Print of the system?

The total solar installation area is calculated on the basis of total daily energy requirement and total insolation in that particular area.
Total solar foot print is 1.5 to 2 times of solar aperture area, as we have to consider space for piping and space for provision of cleaning.
