What is the spectrum performance of the transparent panels?

Polysolar manufactures a standard 20% light transmission panel. This utilises the bulk of the light at the blue spectrum and lets through the light at the red end of the spectrum. The panels absorb 99% of ultraviolet (UV) light and 67% of infrared (IR) light. The panel has a g-value (heat transfer) of 44 and a u-value (insulation) of 4.9 – (in a double glazed unit this is 1.4). Overall shading coefficient 0.51.
