<p>A solar collector (20) which is illuminated by the sun through a glass panel (24) wherein the glass panel (24) is constructed of glass without low-e coatings with a first surface coating (32) of a magnetron sputtered vapor deposition coating consisting primarily of titanium dioxide. The titanium dioxide achieves a hydrophilic photocatalytic surface to produce a solar collector (20) which is self-cleaning for increased solar energy transmittance with less cleaning cost.</p> |
