SOLAR DECATHLON SML 2012 · MADRID, SPAIN
PHOTOVOLTAIC FAÇADE & FLOOR · AMORPHOUS SILICON TECHNOLOGY
Onyx Solar played a key role in the integration of a photovoltaic façade and floor for the 2012 SML system solar house, a project designed by students and researchers from the architecture and engineering departments at CEU University. This innovative design earned second place for innovation in a prestigious competition. The installation is equipped with opaque laminated double-glazing, chosen to maximize energy output, generating approximately 3,500 kWh of clean energy per year. Over a 35-year period, this system is projected to produce 100,397 kWh of electricity, powering 197 lighting points that operate 4 hours a day, while preventing 67 tons of CO₂ emissions from entering the atmosphere.
Additionally, it will save 59 barrels of oil per square meter during the same period. A feasibility study for the amorphous silicon façades revealed a significant reduction in HVAC energy demands by 55%. The return on investment is evident, with a payback period of less than two years, making this a highly sustainable and efficient solution for green energy production.
