The solar cells are embedded between two panes of tempered safety glass. …Essentially, this is a double glazed unit that enhances thermal insulation while it collects energy.
Along with the embedded solar cells is a layer of art glass that is treated and colored to create beautiful, dramatic visual effects behind and around the solar cells. The art glass can be seen from both sides, and creates a glorious interior effect without compromising the collection of solar energy. This additional layer also enhances the insulating qualities of the installation.
