Spectral: Viennese startup builds solar facade for existing buildings

Vezetői összefoglaló (AI)

• Vienna-based Spectral presented its Structural Solar Façade, a system that replaces conventional cladding with semi-transparent photovoltaic modules and is designed for low-intervention retrofits.
• Its first pilot at the Eisfabrik in Vienna-Brigittenau has been producing electricity since September; the installation covers 24 m², uses 32 modules, delivers 1,840 Wp, and is 50% transparent.
• The façade is intended to generate electricity, shade buildings, and still let daylight through; target sites include industrial, logistics, office, public, and multi-storey residential buildings.
• Architects Zsuzsa Péter and Anna Gulinska founded Spectral in early 2024. The City of Vienna supports the pilot in principle but provides no direct funding.
• The pilot yields about 77 Wp/m², compared with more than 200 Wp/m² for conventional rooftop modules; Spectral has not disclosed prices.
