Thermooptical properties of various STPV (10%, 20%, and 30% VLT) and reference glazing models.

Glazing configurations	SHGC (%)	U-value (W/m^2K)	External light reflection (%)	Transmittance VLT (%)	Peak power (Wp/m^2)
Double-glazing low-E argon-filled	0.65	1.1	13	79	—
STPV DG low-E 10%	0.09	1.6	7.3	10	40
STPV DG low-E 20%	0.12	1.6	7.3	20	34
STPV DG low-E 30%	0.17	1.6	7.3	30	28
