3S was founded in 2001 in Switzerland to transform buildings from being energy consumers to become energy producers using solar building materials.
For this, 3S built its own production lines for the solar industry. With the growing international solar industry this become the main revenue driver for 3S. In 2010 3S merged with Meyer Burger to become the leading equipment supplier in the solar industry. In 2018, Patrick Hofer-Noser bought back the Energy Systems division of Meyer Burger and focused entirely on the vision of making the CO2 building free and transform the building skins to become power producing buildings and keeping the aesthetics of the buildings. MegaSlate® roof and facade produces energy reduces CO2 in building materials and is cost effective as a system.
