Analytical solution to the one-dimensional non-uniform absorption of solar radiation in uncoated and coated single glass panes

▸ Absorption-conduction problem inside glass panes exposed to solar radiation. ▸ Analytical solution found which takes into account all the relevant phenomena. ▸ New spectral quantities called direct absorptance moments are introduced. ▸ Implementation of new thermal model in existing software tools is straightforward. ▸ Improvement of accuracy by 3-4% when compared to existing approximate models.
