Balcony modules for Parapet installation are already known. The Finnish glazing specialist Lumon goes one step further. With its EAIL system, the glass parapet itself becomes a PV system.
The solution transforms the glass wall, attached to the balcony as autumn protection, into a current generator.
According to the manufacturer, the PV modules are almost invisibly integrated between two glass windows. Cables and connections are hidden under a lid in the handrail. This creates an aesthetically pleasant solution without visible technical components. Lumon wants to use this argument to address architects and planners.
The system meets the current standards for structural stability, wind loads and safety, according to the company, and is just as stable as conventional Balkonglazing, parapets and handrails. Parapetel elements can be combined to create different balcony dimensions. Further design options are available in black and gray.
In Finland, Erailing was used for the first time in a building renovation. According to the manufacturer, an element of six meters long with an optimal southern orientation and Northern European conditions should generate around 622 kWh of solar energy per year. This corresponds to a module output from approximately 800 W to 900 W. The solution contains no inverter, which must be provided separately by the builder.
