solar facade

Japan’s Kaneka and Taisei have designed their T-Green Multi Solar system to be integrated into walls and window surfaces. The system is available in two different versions – a solid type in which PV laminates are turned into vertical exterior panels or walls, and a variant that achieves transparency through striped solar cells that are integrated into window glass.

Taiwanese manufacturer Heliartec Solutions is offering BIPV panels for building facades that can be designed to mimic different kinds of textures in conventional building materials. The panels can also work as colored laminated safety glass and replace traditional cladding in the ventilated facades of buildings. They vary in length from 60 cm to 240 cm, with widths ranging from 30 cm to 120 cm. Depending on their size, the panels can offer power outputs of 90 W to 150 W per square meter.  

The three-meter prototype consists of nine panels based on an aluminum compound. The PV elements of the facade can be tilted to capture more sunlight.

A façade including 75 glass-glass module with a total output of 15 Kw had been installed on a surface area of an office building in Lithuania. After six months of test operation the involved companies expect that the system’s yield could be up to 800 kWh/kW.
