TEG Solar Facade (for C&I buildings) is a BIPV system designed to replace traditional facade cladding in commercial and industrial facilities-from production halls to warehouses and logistics centers. Its main advantage is integration with the building structure: the modules become part of the facade, not an add-on mounted on the structure, simplifying the design and enabling better use of vertical space, especially when the roof is occupied by installations or has limited structural capacity. The series is based on N-type TOPCon cell technology, supporting high energy output and stable performance in demanding operating conditions. From an execution standpoint, prefabrication and modular installation are key-this solution is designed for quick assembly on-site and adaptability to standard wall frame spacings. Another highlight is its industrial aesthetics with customizable color, texture, and frame options, making it easier to meet the architect's requirements without compromising on PV functionality. For C&I investors, it represents a way to achieve a durable, weather-resistant facade that simultaneously reduces energy costs and supports decarbonization goals.

About the TEG Solar Facade (for C&I building) series

7 answered

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

How does TEG Solar Facade differ from standard rooftop-mounted panels?
TEG Solar Facade is a BIPV system, meaning the modules form part of the building envelope itself rather than sitting as add-on panels on an existing roof structure. They replace conventional facade cladding on industrial halls, warehouses, and logistics centers, so energy production doesn't compete for roof space already occupied by ventilation, skylights, or other equipment. It's engineered from the ground up for vertical facade mounting, not a roof panel adapted for another use.
What warranty comes with TEG Solar Facade modules?
Trina Solar provides a 25-year power output warranty, ensuring the modules maintain their rated energy performance over the facade's long service life. The product warranty covering material and workmanship defects is 2 years. This gap is worth factoring into contractor negotiations and considering additional contractual safeguards during the facade installation phase.
Can TEG Solar Facade replace metal cladding on an industrial production hall?
Yes, that's the primary use case for this series. The system is prefabricated and sized to match typical wall girt spacing used in industrial buildings, so it installs like standard facade cladding while also generating power. It's especially useful where the roof is already loaded with ventilation equipment or has limited load capacity, letting the owner still capture PV yield from the building's vertical surfaces.
What is N-type TOPCon cell technology in TEG Solar Facade, and does it actually matter?
TOPCon is an N-type cell technology with an additional passivation layer that reduces surface recombination losses. In practice, this delivers higher efficiency and more stable output than older P-type cells, particularly at elevated temperatures - which matters on a sun-exposed, dark facade where modules run hotter than on a pitched roof.
Are TEG Solar Facade modules bifacial, generating power from both sides?
No, the TEG Solar Facade series uses monofacial modules, not bifacial ones. This makes structural sense - the module is integrated into the building envelope and its rear side sits against the wall structure, so it has no access to reflected light the way bifacial panels do when mounted on the ground or flat roofs with an exposed underside.
What is the maximum power rating per module, and how many panels does a typical hall need?
Modules reach up to 400 Wp maximum power. The exact number of panels needed for a given facade depends on the available surface area, its orientation, and the target system capacity, so it's worth having the contractor size the layout based on the building's technical documentation.
Can the TEG Solar Facade appearance be customized?
Yes, the series offers a choice of colors, textures, and frame variants, allowing the PV facade to match a project's architectural requirements without sacrificing its energy function. This is a meaningful advantage over conventional PV panels, which have limited aesthetic options and are rarely designed with a building's visual impression in mind.
