Solar fresnel lens for CPV
In the field of solar concentration,the Fresnel lens is one of the important optical components in the concentrating solar system(CPV),the solar Fresnel lens concentrator is that the focus of the lens just falls on the solar chip.when the lens face is perpendicular to the sun,the light will be focused on the cell.which will concentrate more energy,thus requiring a smaller cell area and greatly saving costs.
olar arrays uses Fresnel condenser lens with following benefits :
- High precision optical components
- High precision thin thread forming process
- High refractive index,
- Minimum optical losses
- High transmittance and anti-aging,
- Anti-ultraviolet radiation
The pattern of CPV is very special compared with other fresnel lens. Beacuse that's contrary. And the thickness of the PVC lens is also
higher than other lenses, it can eliminate the distortion of lens caused by solar radiation for a long time.
Ligher than SOG of glass and smaller than SOG of GLass.The spotlight is certainly better.
