MB-SR50N PV

The MB-SR50N PV façade is a state-of-the-art architectural system developed to meet the growing demands placed on modern curtain-wall construction. By integrating photovoltaic (PV) panels, it represents the sustainable evolution of the well-established MB-SR50N mullion-and-transom façade. Its clear environmental advantage lies in its ability to improve a building’s overall energy balance by generating renewable electricity on site.

The MB-SR50N PV system is designed for zero-energy façades using both transparent and opaque PV panels. Owing to its excellent thermal performance, it enables the design of buildings with very high energy efficiency.

A distinctive feature of this façade is its specially designed profiles with internal chambers that accommodate cabling and connect the entire electrical installation. The system also includes a single-sided open transom that allows convenient inspection and maintenance of the wiring and connected devices. A purpose-designed installation gland enables the sealed passage of electrical cables from the exterior to the interior of the façade. To maintain neat cable management, electrical wiring routed through the mullion and transom chambers is secured in dedicated clips.

The MB-SR50N PV façade is fully compatible with the MB-SR50N system, meaning that both solutions can be combined within a single project. This allows designers to achieve a uniform appearance from inside and out. The façade construction not only ensures reliable performance and the benefits of photovoltaic technology but also enables fast, non-invasive diagnostics without mechanical intervention from the exterior. All these characteristics make the MB-SR50N PV façade an ideal choice for projects aligned with the principles of sustainable development and energy-efficient architecture.

Benefits of the MB-SR50N PV façade

• for architects: design flexibility for curtain-wall layouts using mullion-and-transom construction; identical appearance of façades with or without PV panels.
• for fabricators: simple processing and installation of PV panels from various manufacturers.
• for users and developers: on-site energy generation for building systems; lower energy costs; reduced building emissions and improved energy balance; identical interior and exterior appearance to a traditional mullion-and-transom façade.

Features and advantages of the system

• profile dimensions: mullions 105 – 145 mm, basic and half transoms 109.5 – 149.5 mm.
• option for additional profile reinforcement.
• optimised profile geometry designed to accommodate electrical installations within the façade structure.
• compatibility with photovoltaic modules from different manufacturers.
• mullion and transom chambers adapted to standard PV electrical connectors and closed with the same cover cap.
• possibility of inspecting the installation through mullions or transoms, from either the interior or exterior.
• full integration with the MB-SR50N façade system: shared cover caps, load-bearing profiles, and system accessories; the PV façade can be combined with the standard mullion-and-transom version and glazed using the same methods.
• high airtightness and watertightness parameters identical to those of MB-SR50N.
• structural solutions enabling easy diagnosis and replacement of a damaged PV cell without interfering with the façade assembly.
