Panes - Solar data

Solar tab on Panes Dialog.

 

For uncoated glass, when alternative optical properties are available, such as thickness, solar index of refraction, and solar extinction coefficient, they can be converted to the equivalent solar transmittance and reflectance values using the equations given in Glass Optical Properties Conversion.

 

This data is not used in simulations when the Data type is 2-Spectral but it is still displayed because it gives a spectral-average overview of the pane's solar transmission and reflectance.

Solar transmittance

The solar transmittance for the pane at normal incidence averaged over the solar spectrum.

Solar reflectance

The inside (back-side) and outside (front-side) solar reflectance properties of the pane at normal incidence averaged over the solar spectrum.

Note: For uncoated glass, when alternative optical properties (thickness, solar index of refraction, and solar extinction coefficient) are available, they can be converted to equivalent solar transmittance and reflectance values using the equations given in the Glass Optical Properties Conversion topic.
