SPHELAR® BIPV

BIPV (Building-integrated photovoltaics)

Glass curtain wall in the middle of city or see-through noise barriers on highway may become solar plant. That vision is realizable with Sphelar®.

With excellent performance in the case of horizontal installation and high see-throughness, we propose Sphelar® as innovative solution for BIPV market.

Effective in both of see-through panel and curved surface

You can enjoy the light shining through your window while generating electricity. Sphelar® see-through module has high transparency in comparison with ‘light-through’ PV products in the market.

Spheres bring more in cumulative energy

Based on crystalline silicon balls, Sphelar® module yields more in cumulative energy. Not only the photoelectric conversion efficiency, but also how much incoming light the cells can absorb during a certain period is important in practical use.
What is more, Sphelar® module is more practical solar since it is supposed to be less dependent on heat and partial shadowing than conventional solars.
