ENEOS Holdings Inc. and Nippon Sheet Glass Co. Ltd. have begun Japan’s first installation of transparent solar panels for use as building windows. The transparent solar windows were developed and fabricated by Ubiquitous Energy and installed at NSG’s facility in Japan with funding support provided by ENEOS, according to a press release.
The statement also noted the purpose of the installation is to verify the energy savings performance (heat blocking and insulation) and power generation capabilities of Ubiquitous Energy’s transparent solar windows under Japan’s sunlight and weather conditions. ENEOS and NSG will perform quantitative evaluation together at NSG’s Chiba Plant over a one-year period (from September 1, 2021, to August 31, 2022). The companies are considering performing additional installations in buildings and the potential to connect them to solar power generation systems with a view to providing power in the future.
Ubiquitous Energy’s transparent photovoltaic coating, UE Power, generates electricity from non-visible light. The UE Power coating generates electricity on the full surface of the window glass without patterns, borders or color tints. The electricity is collected and transmitted through wiring built discreetly into the window frame and fed into the building to power various products or increase its overall energy efficiency.
