A Review of Solar Photovoltaic Concentrators

Table 6

Comparative analysis of different CPV systems from economic aspects [49].

Primary concentrator	Secondary concentrator	Tracking system	Concentration ratio	Cost; $/Wp
Point focus Fresnel lens	No	Gimbals	36	1.48
Cylindrical paraboloid	Point-focus CPC	Polar	65	1.78
Linear Fresnel lens	Solid CPC	Gimbals	37	2.02
Curved TIR lens	No	Polar	28	1.97
Curved Fresnel lens	No	Polar	15	2.18
V-trough, screen printed	No	Polar	2	4.31

The costs given in the table are for cells, optical systems, mountings, and trackers only, including construction costs; balance of system costs are omitted as they are similar for all types of collector. The cost in $/Wp is for collectors at operating temperature and, for concentrators, is based on direct beam irradiance of 850 W/m²; the cost for the flat plate is based on a total irradiance of 1000 W/m² [49].
