The BIPV sunroom developed by Solar First Group made a brilliant launch in Japan.

The Japanese government officials, entrepreneurs, professionals in solar PV industry were eager to visit this product’s installation site.

The R&D team of Solar First developed the new BIPV curtain wall product with vacuum and insulating Low-E glass, which perfectly integrates photovoltaic, the renewable energy, into sunroom, and form a “net-zero energy” building.

The patent information of Solar First’s BIPV technology lists as follows:

Product: A Vacuum Low E Solar Glass Used for Building Integrated Photovoltaic

Patent No.:2022101496403 (invention patent)

Product: Photovoltaic Curtain Wall

Patent No.: 2021302791041 (design patent)

Product:A Solar Photovoltaic Curtain Wall Device

Patent No.: 2021209952570 (patent for utility model)

As reported by the Japanese media Ryukyu Shimpo, the Ryukyu CO₂ Emission Reduction Promotion Association regarded Solar First’s solar glass product as “ace” solar glass. The president of Moribeni, Solar First’s agent company in Japan, Mr.  Zhu highly recognized the corporate philosophy “New Energy, New World”, and highly praised the spirit of Solar First’s hard work in innovation. Mr.  Zhu emphasized that his team will do their level best to promote “Net Zero Energy Building” in Japan.

The front-page headlines in detail is shown below:

“Power Generating Glass” Model House

Moribeni, the member (Mr.  Zhu, representative of Naha City) of Ryukyu CO₂ Emission Reduction Promotion Association, used the laminated glass with power generation function to build a power generating glass model house. According to this association, this structure was realized at the first time. This association regard the solar glass as its “ace” to promote the “Net Zero Energy Building”.

The wall can generate electricity

ZEB（Net Zero Energy Building）, means to save energy and reduce energy consumption while keeping comfortable living conditions, thereby to balance the energy of building. Under the trend of global decarbonization, the importance of ZEB will be increasing.

The top and wall of model house were covered by heat-shielding, heat-preserving, power generating, Low-E laminated glass. The light transmittance of top was 0%, while the wall 40%. The installation capacity of solar power system was 2.6KW. The model house is equipped with an air conditioner, a fridge, lamps and other devices.

The solar glass could be made with wood texture. Mr. Zhu said, such design would be good for environment and cost effective under the circumstance of increasing electric charge, while shielding and preserving heat.

This association claimed that there were 8 buildings in Okinawa Prefecture planning to be ZEBized. Zukeran Tyojin, the representatives of this association, said it’s difficult to realize ZEB by only installing solar panel on rooftop of houses in city, and it’s important to utilize the walls. He hoped everyone could visit this model house and form a good image of ZEB.
