The new panel has a nominal power of 395 W and a claimed temperature coefficient of 0.28% degrees Celsius.
Dutch startup Solar Visuals and the Netherlands Organisation for Applied Scientific Research (TNO) have developed new “mimic design” facade modules that reproduce the features of building surfaces. Lenneke Slooff-Hoek, a senior scientist for TNO, told pv magazine that the panels can be made in any size or color at 13% efficiency, adding that they have a partly transparent colored layer made of small dots.
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.
