About Wellsun

The Lumiduct from Wellsun is an elegant solution for making buildings more sustainable and livable. Buildings with the Lumiduct come to life.

During the day, the facade is activated by brilliant transparent solar panels, enabling the building to generate and save energy. At night, the facade is activated by using integrated LEDs creating a beautiful atmosphere and making it possible to communicate with the surroundings. The Lumiduct generates awareness of the dedication to sustainability and makes living in buildings featuring it a unique and comfortable experience.

By selectively shielding intense, direct light from the sun, building occupants will no longer experience harsh glare or heat, resulting in up to 40% savings on cooling costs. Because the solar panels are transparent, up to 3 times as much soft, diffused daylight will enter the building, resulting in up to 30% savings on artificial lighting costs. With the Lumiduct, we no longer have to fight the sun; we can embrace it and with that, make optimal use of its power. With the Lumiduct, only the light we need enters the building, while the light we do not need, is turned into electricity.

Due to its design, the Lumiduct is not affected by dust or high temperatures, therefore the solar panel efficiency (30%) is maintained over its lifetime. The Lumiduct requires no maintenance and high performance is guaranteed. With Wellsun’s professional supply chain, any project, no matter the size or design, can be delivered successfully.
