The Trina Solar Solar Facade series redefines the approach to modern architecture, combining clean energy generation with the aesthetics of building facades. This solution effectively eliminates the problem of limited roof space, transforming external walls into active power sources. These panels utilize advanced Building Integrated Photovoltaics (BIPV) technology, allowing for their full integration with the building structure without compromising on design. Thanks to the use of glass-glass construction, this series ensures the highest fire resistance class and exceptional mechanical durability, which is crucial in demanding urban environments. Architects and investors appreciate the wide range of available finishes, which turn the modules into a prestigious visual element rather than just a technical component. The use of high-efficiency silicon cells guarantees stable energy production even with vertical mounting and diffused light. It is an ideal choice for projects aiming for LEED or BREEAM green certification, offering excellent thermal and acoustic insulation at the same time. Trina Solar Solar Facade stands out from the competition with its precision craftsmanship and ability to adapt to the most ambitious architectural visions, where functionality must go hand in hand with a luxurious appearance.

About the Solar Facade series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

How does the Trina Solar Solar Facade series differ from standard rooftop panels?
Solar Facade modules are BIPV (Building Integrated Photovoltaics) products designed for mounting on building facades rather than rooftops. Their glass-glass construction allows them to serve as building cladding while generating electricity. Unlike standard rooftop panels, they come in a wide range of aesthetic finishes and provide additional thermal and acoustic insulation for the building.
What warranty comes with Trina Solar Solar Facade panels?
The manufacturer provides a 2-year product warranty and a 25-year power output warranty. The shorter product warranty compared to standard rooftop modules reflects the specific nature of facade installations, so it's worth confirming additional service terms with your installer for this type of mounting.
Are Solar Facade panels suitable for LEED or BREEAM certification projects?
Yes, the Solar Facade series is designed for projects pursuing LEED or BREEAM green building certification. Integrating photovoltaics into the facade helps earn points in renewable energy and building efficiency categories while reducing the need for additional cladding materials.
Do Solar Facade panels generate enough energy when mounted vertically?
Yes, the modules use high-efficiency TOPCon silicon cells that maintain stable energy production even in vertical mounting and diffuse light conditions typical of building facades. With up to 400 Wp maximum power, they effectively utilize large wall surfaces despite the less favorable sun angle compared to a roof.
Are Solar Facade panels bifacial?
No, the Solar Facade series uses monofacial modules. The glass-glass construction is primarily used for its high fire resistance rating and mechanical durability rather than for capturing reflected light on the rear side, which is typical of bifacial ground-mount installations.
Does installing Solar Facade panels require special facade construction?
Yes, Solar Facade panels require a dedicated BIPV mounting system integrated into the building's structure rather than standard roof rails. Due to the fire resistance class and finish requirements, the installation should be planned during the architectural design phase in collaboration with an architect and a certified BIPV installer.
