CertainTeed seems to be a distributor of SunStyle solar modules. The modules were installed on top of a Google structure in California.
The modules were designed by a European group. SunStyle is the brand name. They’re standard solar cells that go in a regular solar panel, but in a different form factor than the mass produced units. They have a highly reflective surface, last a *long time*, and are used to cover 100% of the roof, instead of just the perfect sunlight spot.
