A collaboration between Saint-Gobain Glassolutions, Onyx Solar and Comenza has integrated photovoltaic glass into a railing system of an apartment building in Spain.
Glass processing specialist Saint-Gobain Glassolutions has developed its first integrated solar power project utilizing solar railings.
The solar railings have been implemented on a residential building located in the port city of Cádiz, southwestern Spain. The building, built in 1966, exhibited deficiencies including a lack of thermal insulation in the façade and roof, low-energy-performance window frames and numerous thermal bridges that negatively affected its energy efficiency.
The solar railing installation is known as the Conecta Solar solution, jointly developed by Saint-Gobain Glassolutions, Soria-based building-integrated photovoltaic company Onyx Solar and Comenza, a Galician company specializing in the manufacture of glass and stainless-steel railings.
The Conecta Solar solution received an award at the NAN Architecture Awards 2025 for best photovoltaic material. The range is available in both crystalline silicon and amorphous silicon, with different configurations, power outputs, and design options.
