Solar Transmittance

Solar transmittance, also referred to as light transmittance or visible transmittance, is the measurement of visible light passing through a piece of glass. Solar transmittance can be altered by the addition of glass coatings, etchings, solar films, and more. It is measured as a percentage where 100% would be completely clear and transmit all the light, while 50% would only let half the light through.
