concentrating solar collector
The main types of concentrating collectors are:
• parabolic dish collectors
• parabolic trough collectors
• power tower
• stationary concentrating collector
A PV concentrating module uses optical elements (Fresnel lenses) to increase the amount of sunlight incident onto a PV cell. Concentrating PV modules/arrays must track the sun and use only the direct sunlight because the diffuse portion can't be focused onto the PV cells.
Concentrating collectors for home or small business solar water heating applications are usually parabolic troughs that concentrate the sun's energy on an absorber tube (called a receiver), which contains a heat-transfer fluid.
